Debris and Friction of Self-Ligating and Conventional Orthodontic Brackets After Clinical Use
Objective: to compare the degree of debris and friction of conventional and self-ligating orthodontic
brackets before and after clinical use. Methods: two sets of three conventional ligated (n=16) and selfligating brackets (n=16) were bonded from the first molar to the first premolar, on 8 individuals, after
a passive segment of 0.019’ x 0.025’ – inch stainless steel archwire was inserted into each group of
brackets. Frictional force and debris level (via magnifying lens) was evaluated as-received and after 8
weeks of intraoral exposure. Two-way Anova, Wilcoxon signed-rank, and Spearman correlation were
applied to statistical analysis at 0.05 level of significance. Results: friction level in conventional brackets was significantly higher when compared to self-ligating brackets before clinical use (p<0.001).
Clinical exposure for 8 weeks provided a significant increase of friction (p<0.001) and the debris score
( p< 0.05) on both systems. To self-ligating brackets, friction raised in average 0.21 N (191%) while
for conventional ones, this values was 0.52 N (47.2%). Micorscopic analisys showed a 50% gain in
slots dirtiness from self-ligating brackets compared to conventionals. Conclusion: Self-ligating and
conventional brackets when exposed to the oral environment for 8 weeks showed a significant increase of friction during the sliding mechanics and in superficial slots debris. Quests about the effect
of this on orthodontic treatment time should be investigated.

Evaluation of buccal and lingual alveolar bone crest level of mandibular second molars pre and
posttreatment by Cone-Beam Computed Tomography: Preliminary results
Objectives: The purpose of this study was to evaluate and to compare, by means of Cone-Beam
Computed Tomography, the buccal and lingual bony dehiscences of mandibular second molars before and after molar uprighting and also to compare the alveolar bone morphology between groups.
Methodology: Nine CBCT exams were taken of patients without first molar with voxel dimensions
of 0.2 mm and field of view of 6cm using the i-CAT Cone-Beam 3-D Dental Imaging System. Images of CBCT were divided into two groups: Group 1 (9 uprighting second molars) and Group 2 (7
non-uprighting molars). Linear measurements were performed using the i-CAT vision on crossectional sections between cement-enamel junction of second molar and upper area of the alveolar bone
crest. Dependent t tests were used to evaluate the alveolar bone crest level pre and posttreatment within group. T tests were used to evaluate intergroup differences regarding the periodontal morphology.
Results: There was no significant difference between alveolar bone height pre and posttreatment in
both groups, however bone dehiscences were significantly higher in Group 1. Conclusions: Although,
uprighting second molars have bone crest level reduced, it is possible to control the dehiscences during the orthodontic treatment.

Force decay between intermaxillary elastics with and without Latex: in situ study
Objective: To evaluate force decay between intermaxillary orthodontic elastics with and without latex, in the oral medium in different time intervals. Materials and Methods: Intermaxillary orthodontic
elastics with and without latex, of 1/8, 1/4 and 5/16 in diameter were evaluated in an in situ study. For
this purpose, 26 patients served as hosts for the elastics during the evaluation period. Initially, on the
molds of these patients, 52 thermoplasticized plates 1 mm thick were made, onto which the orthodontic accessories were bonded, and these served to maintain the elastics distended (30 mm) throughout the experimentation period. The force released by the elastics at this distance was evaluated in the
time intervals of0, 12 and 24 hours. Statistical analysis of the results obtained was performed using the
Friedman, Wilcoxon and Mann-Whitney tests, adopting a 5% level of significance. Results: elastics
with and without latex presented permanent deformation and increase in internal diameter throughout the entire period. Elastics with latex, 1/8 in diameter maintained higher levels of force than those
without latex. Elastics measuring 1/4 and 5/16 without latex presented a higher level of force in time
intervals of 0 and 12h compared with those with latex, but at the end of the experiment (24h) no
significant difference was observed between them (p>0.05). Conclusion: Intermaxillary elastics with
latex presented a higher level of force and underwent less degradation than those without latex.

Tooth wear as an estimator of chronological age in amazon indigenous
The age in indigenous populations is estimated based on family structure and physical examination
performed by a medical and dental staff, as well as anthropologists. However, the accuracy of existing
methods is questionable because the main criteria used to limit its precision in children. The aim of
this study is to evaluate the occlusal tooth wear, as an estimator of age in indigenous populations of the
Xingu. We examined 263 individuals on permanent dentition. Forty individuals living in an urban
area, Belém – PA (Brazil), were used as control group, and 223 were Indigenous from the Middle Valley of Xingu. In the indigenous population 126 belonged to ethnic Arara, 62 Xicrin-Kayapó and 46
Assurini. A modifief ooth wear index was used according to Mockers, Mafart and Aubry (2004). Data
were statistically examined by linear regression analysis at 95% confidence. We observed a strong association between tooth wear and chronological age in indigenous populations. The wear was able to
explain 86% of the variation in age at Arara ethnicity, 69% among Xicrin-Kaiapó and 64% in group
Assurini. In the urban population only 10% of age could have determined by tooth wear. Tooth wear
can be used as a helpful reliable index to determine chronological age in indigenous populations from
Xingu River.
Keywords: Age Determination by Teeth, Tooth Wear, Indigenous Population.

Effectiveness of varnish with CPP-ACP in Prevention of Caries Lesions around Orthodontic
Brackets: An OCT Evaluation
Objective: To evaluate the in vitro efficiency of applying varnish containing Casein Phosphopeptide
(CPP) and Amorphous Calcium Phosphate (ACP) in prevention of caries lesions around orthodontic
brackets. Materials and Methods: For this purpose, brackets were bonded to the vestibular surface
of bovine incisors, and eight groups were formed (n=15) according to exposure of oral hygiene substances and enamel varnish: 1 (control) brushing only performed, 2 (control) brushing + use of mouth
wash with fluoride, 3 Duraphat varnish application only (Colgate-Palmolive Ind. E Com. Ltda, São
Paulo, SP, Brazil), 4 Duraphat + brushing, 5 Duraphat + brushing + mouth wash, 6 MI varnish application (GC America, United States, USA), 7 MI + brushing and 8 MI+ brushing + mouth wash.
The experimental groups alternated between pH cycling and the procedures described, and were
kept in an oven at temperature of 37°C. Both brushing and immersion in solutions was performed
in a time interval of 1 minute, followed by washing in deionized water three times a day for 28 days
of experimentation. Afterwards evaluation by Optical Coherence Tomography (OCT) of the special
type (Ganymede OCT/Thorlabs, Newton, USA) was performed. In each group a scanning exam of
the white spot lesion area (around the region where brackets were bonded) and depth measurement of
caries lesions were performed. Results: Groups 1 and 3 were shown to differ statistically from Groups
5, 6, 7, and 8 (p=.000). MI varnish was shown to be more effective in diminishing caries lesion depth,
when compared with Duraphat, irrespective of being associated with brushing and mouth wash,
or not. Conclusion: Application CPP-ACP-containing varnish irrespective of being associated with
brushing and mouthwash, or not, reduced depth of caries lesions around orthodontic brackets.

Primary palatoplasty impact on maxillomandibular sagittal relationship of UCLP patients: A
systematic review and meta-analysis.
Objective: To evaluate through a meta-analysis isolated effects of lip and palate primary surgery on
sagittal maxillary and mandibular relationship among unilateral cleft lip and palate (UCLP) patients.
Methods: This meta-analysis was registered at PROSPERO. A search on electronic databases was
done using the terms “cleft lip palate”, “growth”, “surgery” and “repair”. Hand search and “grey
literature” was also performed. Only controlled clinical trials, retrospective or prospective, with nonsyndromic unilateral UCLP, published between 1960 and 2012 were included. Selected papers were
assessed by two researchers and must include one group of UCLP operated on lip and palate compared
to operated only on the lip. Data heterogeneity was tested and then individual means, SD and sample
size were collected and summarized using a random effects model meta-analysis. Results: Six articles
were selected for the systematic review, but just 4 were included in the meta-analysis. Although all
studies performed lateral cephalometric analysis, just SNA, SNB and ANB were common between
them. Statistical analysis didn’t show significant differences for SNA and SNB between patients operated only on lip from lip and palate surgery. ANB evaluation showed a small, but statistical difference.
Conclusions: Impaired sagittal growth of the maxilla observed in patients with unilateral cleft lip and
palate, is a basic consequence of lip surgical repair. Changes produced by palatal repair on maxilla and
mandible are insignificant. Palatoplasty seems to cause a minor, but statistically significant, change on
intermaxillary relationship.

Perception of severity of malocclusion index in the primary dentition (PSMI): development and
validation
Aim: To develop and validate a perception of severity of malocclusion index (PSMI) for the primary
dentition. Methods: The sample consisted of 294 children 3-5 years of age. A calibrated professional
examined children for the presence and severity of malocclusion. The severity was indicated by a
visual scale of 10 points (less severe 1 - 10 most severe). Descriptive analysis, linear regression uni /
multivariate and post hoc Mann-Whitney tests were used. Results: The types of malocclusion independently associated with perception of the severity of malocclusion were: lip coverage (p˂0.001),
crowding (p˂0.001), diastema in millimeters (p=0.002), open bite in millimeters (p˂0.001), overbite
in millimeters (p=0.010) and anterior crossbite in millimeters (p ˂ 0001). The linear regression equation allowed the construction of the index as follows: IPSM = (lip coverage X 3) + (crowding X 2) +
(diastema X 0.5) + (overbite X 0.5) + (anterior open bite X 1) + (anterior crossbite X 2) + 3. The sum
of the PSMI scores will indicate whether the child has malocclusion absent (3.0 to 4.0), mild (4.1 to
5.4), moderate (5.5 to 8.9) and severe (≥ 9). Conclusion: The classification of malocclusion severity
(absent, mild, moderate and severe) according to the IPSM demonstrates the applicability of the instrument in epidemiological surveys and clinical.

The undergraduate orthodontics teaching and general practice under the student perception
The purpose of this paper is to identify if the undergraduate orthodontics contributes to form general
practice besides the national curricular guidelines (NCG) established by the Ministry of Education
and Culture (MEC) from Brazil. This is a transversal, investigative and quantitative study with 225
senior undergraduate students of five different dentistry schools from Minas Gerais, Brazil. It was applied a questionnaire of 37 questions, 36 closed questions and one open question. All questions were
related to personal data, content taught, teaching methodology, orthodontics skills (measured by diagnoses and treatment decision) and the intention of to realize preventive and interceptive procedures,
nominated in this paper as autonomy. From all 232 undergraduate students, only 225 questionnaires
were able to the study, with a 3,02% of non-response questionnaires. Just 37,5% of undergraduate students answered that would do orthodontics procedures after college. The orthodontics skills
showed up association with to do orthodontics procedures option in their professional career as well
to discuss clinical events with the professors as teaching methodology (p≤0,05). This paper concludes,
inspire of the NCG demands, that undergraduate orthodontics of researched dentistry school didn’t
contribute on all the way on the general practice formation until now.

The effect of CCL3 and CCR1 in bone remodeling induced by mechanical loading during
orthodontic tooth movement in mice
Objective: Bone remodeling (BR) is affected by mechanical loading and inflammatory mediators,
including chemokines. The chemokine CCL3 is involved in BR by binding to chemokine receptors
CCR1 and CCR5 expressed on osteoclasts and osteoblasts. Our group has previously demonstrated
that CCR5 down-regulates mechanical loading-induced bone resorption. In this study we investigated the role of CCR1 and CCL3 in BR induced by mechanical loading during orthodontic tooth
movement (OTM) in mice. Methods: A coil spring was placed in C57BL6/J, CCL3-/-, CCR1-/, vehicle and Met-RANTES (an antagonist of CCR5 and CCR1) treated mice. Histopathologic
analysis revealed the amount of OTM and osteoclasts. The expression of mediators involved in BR
was evaluated by RT-PCR. Results: BR was significantly decreased in CCL3-/- and CCR1-/- mice
and in animals treated with Met-RANTES. mRNA levels of RANK, its ligand RANKL, tumor
necrosis factor alpha (TNF-α) and RANKL/osteoprotegerin (OPG) ratio were diminished in the
periodontium of CCL3-/- and Met-RANTES-treated mice. Met-RANTES treatment also reduced
the levels of cathepsin K and metalloproteinase 13 (MMP13). The expression of the osteoblast markers RUNX2 and periostin was decreased, while osteocalcin (OCN) was augmented in CCL3-/- and
Met-RANTES-treated mice. Conclusion: Altogether, these findings show that CCR1 is pivotal for
BR induced by mechanical loading during OTM and these actions depend, at least in part, on CCL3.

The influence of components of the PAR Index on patient satisfaction after adult orthodontic
treatment.
Objective: To evaluate if any single factor of the PAR Index influences on the degree of adult patient
satisfaction after orthodontic treatment in the long term. Methods: Were analyzed, through the PAR
index, occlusal changes occurring after the orthodontic treatment in the long term (5 to 25 years - an
average of 8.5 years) using plaster models of 208 adult patients treated with straight-wire orthodontic
fixed appliance. The index questionnaire of Dental Impact Daily Living (DI DL) was used to assess
patient satisfaction with the outcome of orthodontic treatment in the long term and see which components of the PAR Index were more relevant to the patient. Multiple linear regression analysis and
step by step were used to evaluate the influence of the dependent variables, satisfaction and appearance, with the independent variable, PAR Index components. Results: The components of the PAR
Index show a determination in 17.2% (p <0.0001) on the total satisfaction of the patient regarding
their dental occlusion in at least 5 years after treatment (p <0.0001). The DIDL shows the appearance
as the most relevant category to the patient, being influenced by the PAR index in 31.8% (p <0.0001).
The PAR Index measures that had more determination on satisfaction were the anterior superior
17.79% (p <0.0001), anterior inferior 12.07% (p <0.0001) and overjet 1.99% (p = 0.0148). Conclusions: The factors of the PAR index had weak association with satisfaction and moderate association
with appearance of adult patients after orthodontic treatment in the long term. The PAR Index measures that had more significance were those related to the esthetic area.

Spontaneous dimensional changes of the lower arch for young adults with orthodontic treatment.
This study evaluates the changes of spontaneous alignment of the lower dental arch and its dimensions, using a longitudinal study in young adults without orthodontic treatment. Twenty pairs of
plaster’s models of the lower arch were obtained in two stages. In the first test, subjects had an average
age of 20.25 years, while in the second test, the average age was 31.2 years. The results indicate a significant reduction of the dimensions of the arc, in the inter-canine width (P = 0.0089), in the length
of the right (P = 0.001) and left arch (P <0.001), in the inter-molars width (P = 0.022), which resulted
in an increase Little irregularity index (P <0.0010). Changes in the Little Index showed no statistically
significant association with changes in arch dimensions, and cannot be predicted from the severity by
the end of the second life decade (P = 0.5051). The results suggest that the post-growth maturation
process of the lower arch leads to a reduction of the dimensions of the arch and a mild significant increase of the crowding, even in individuals without orthodontic treatment.

The ability of maxillofacial surgeons and orthodontists to predict the eruption of mandibular third
molars.
Aim: The aim of this paper was to evaluate the ability of maxillofacial surgeons and orthodontists to
predict the eruption of mandibular third molars. Materials and methods: seventeen panoramic radiographs of orthodontically treated patients, nonextraction cases, ranging from 11 to 17 years old. The
radiographs were digitalized and presented along with a questionnaire to 56 professionals, who were
28 orthodontists and 28 oral and maxillofacial surgeons. Then they were requested to express their
opinions on how to proceed toward the right and left mandibular third molars. In a follow up clinic
and radiographic evaluation, when the patients were over 18, the total eruption of all third molars
(n=34) included in the sample was attested. A radiograph was doubled in order to evaluate the error
of the method. Findings: An excellent reliability was observed between maxillofacial surgeons and
orthodontists (Kappa= 0.76; p<0.0001). The intra-group reliability was also excellent to orthodontists
(Kappa= 0.96) and surgeons (Kappa= 0.83). Extraction was the decision for 49,6% of the surgeons
and 61,6% for orthodontists (p<0.0001). Nevertheless, both experts suggested a considerable number
of extractions, proving to be unable to predict the eruption of the mandibular third molar. Conclusion: Orthodontists and maxillofacial surgeons are not able to predict the eruption of mandibular
third molars. Consequently, they tend to indicate unnecessary extractions.

Facial morphology analysis of indigenous people from middle xingu valley
Objective: To evaluate comparatively the characteristics of indigenous face morphology from the
Middle Xingu Valley. Methods: The sample was composed of 106 indigenous, in permanent dentition, belonging to villages Arara-Laranjal (n=35), Arara-Iriri (n=20), Xicrin-Kaiapó (n=24) and Assurini (n=27). We analyzed 14 facial measurements obtained from standardized frontal and profile
photographs. The comparison between groups was performed using ANOVA or Kruskal-Wallis test
and the sexual dimorphism for each village was analyzed by Student´s t test or Mann-Whitney at
p<0.05. The homogeneity within and between groups was examined throug the discriminan analysis. Results: Significant diferences were found among the males and females indigenous in all villages.
Through the discriminant analysis was observed a large intertribal heterogeneity of face features, at
the same time that na intratribal homogeneity was found, mainly for females individuals. Some morphological characteristics of the face are specific to certain groups, regardless the ethnicity. Conclusion: Indigenous populations have morphological characteristics of the face that allow to discriminate
each investigated group. These findings gives support to the role of genetics determining craniofacial
growth.

Objective: to compare the survival of bonding and banding molar attachements in adult orthodontic
patients. Methodology: The survival analysis was examined through a split-mouth design carried out
on 32 patients, in which one molar was bonded in one side and the contraleral molar was banded. At
the opposite arch the bonded and banded molars were crossed. A total of 59 banded and 59 bonded
molars were followed-up for 12 months. The operators were nineteen students of Orthodontics course
in Brazilian Odontology Association - Pará section. Log Rank survival analysis (Rosner’s method)
was used at P<0.05. Results: Survival of bonded molars was not statistically different of banded molars
(p = 0,97). Bonded upper molars presented a survival of 81,25% while banded upper molars survival
was 71,87% (p=0,70). Survival rate was of 66,66% for banded lower molars and 59,25% for bonded
lower molars (p=0,69). Conclusion: in adult patients, bonded molars present a failure rate similar to
banded molars.

Arch dimensional changes produced by primary molar proximal caries, according to the tooth
decayed.
With the aim of evaluating dimensional arch changes, measured by DE space and diagonal arch length
(DAL), in patients that presented proximal carie on lower or upper primary molar, a sample composed
by 52 chidreen, 30 (57.7 %) girls and 22 (42.3 %) boys, was selected to this investigation. Mean age
during the arch impression was 7 years and 3 months (3.4 y - 9.8 y). Every children was in the primary
or mixed dentition stage and showed one hemi-arch with proximal carie (experimental side) and the
contralateral arch was carie free (control side). In one individual both arches were examined, totalizing 53 hemi-arches included in the sample. Student’s paired t test was used to evaluate the differences
between carie hemi-arch and the control side while Student’s t test for independent samples was used
to examine differences between changes observed in 1st primary molar against 2nd molar and alterations observed on the upper versus lower arch. Findings showed that there is a significant decrease on
the DE space and DAL in the proximal carie side. No difference was observed if the proximal carie is
placed on the 1st or 2nd primary molars or on the upper or lower arch.

Cephalometric Evaluation of Naso and Oropharyngeal Space in Patients with Different Types of
Atypical Swallowing
Knowing the importance of the upper airway for a normal breath and hence for the skull and face
growth development, it’s important to know how and how much the pharyngeal space grows. Thus,
this study was developed to evaluate the growth of the upper airways through radiographs. This study
aimed to evaluate the growth of the upper airways through radiographs as to verify whether changes
would occur in the pharyngeal space in patients with different atypical swallowing patterns, which
is defined by the position of the tongue in the oral cavity, which may be high, medium or low. This
study involved lateral cranial radiography (45 images: 15 for each type of atypical deglutition) taken
from patients aged 6 to 10 years, both genders. Cephalometrically was measured in four linear measurements: Pa-Pp and Su-In, order to evaluate the nasopharyngeal space, and Oa-Op and Ma-Mp, to
the oropharynx. After collecting the data, they were statistically evaluated by means of average values
in order to verify possible differences between different atypical swallowing patterns. By checking the
mean values for each variable, one can see change more expressive of oropharyngeal space in patients
with atypical swallowing low.
Keywords: Cephalometry, oropharynx, nasopharynx, atypical swallowing.

Assessment of the effectiveness of mouthwashes in reducing cariogenic biofilm in orthodontic
patients: A systematic review.
Objective: to evaluate the effectiveness of mouthwashes to reduce the cariogenic biofilm in orthodontic patients. Materials and methods: a systematic literature search was conducted in the following
electronic databases Scopus, PubMed, Web of science, Medline, Embase and Cochrane, Grey literature and Controlled Trials without limitations of year of publication or language. We included clinical studies in patients with fixed orthodontic appliances you were using mouthwashes to reduce the
cariogenic biofilm. Articles with systemic drug users, patients of jaw, in use of shampoo with other
purposes eou in use of different hygiene techniques as well as clinical cases were excluded. After selection by title and abstract, potentially eligible articles were read in their entirety. The methodological
quality and the risk of bias of the articles included were evaluated according to the characteristic of
the study, measurements of the study and statistical analysis. The methodological quality was classified
as high, moderate or low. Results: the survey identified 2,716 articles, 22 of which met the inclusion
criteria. Of these, 8 have analyzed enxaguantes chlorhexidine base, while article 1 the use of cetilpiridinio, 1 analyzed the rinse aid with bloodthirsty, 1 using NaF, 2 articles from AmFSnF2, 2 the use
of Listerine ®, 1 still analyzed the association between enxaguantes with octenidina and PVP-I. The
articles analyzed 10 were classified with high and 5 as moderate methodological quality. In the studies
reviewed here using the mouthwash was effective in reducing the cariogenic biofilm in orthodontic
patients. Conclusions: the evidence of the effectiveness of the use of mouthwash in the control cavity producing biofilm in patients with fixed orthodontic appliances are high. So, Orthodontists may
suggest the use of rinse aid in the oral hygiene of their patients as an adjunct to reduce the cariogenic
biofilm.

Longitudinal evaluation of retromolar space of the dentition in 4-8 year children by cephalometric
radiography.
The aim of this evaluation was to measure longitudinally the retromolar space in lateral cephalometric
radiographs using the method of Merrifield, adapted for the primary dentition in order to observe the
amount of subsequent growth of the lower arch, the space for the first and second permanent molars
and determine sexual dimorphism. A sample of the file area of Orthodontics, FOP / UNICAMP,
which consist of 40 patients, 17 male and 23 female, with characteristics of normal occlusion between
the ages of four to eight years, who underwent annual examinations of buccal health, occlusion and
the integrity of the stomatognathic system, panoramic radiography and lateral radiograph and examination of models. The results showed that there was an increase in ramus height of 5.75 mm at 11.75
mm of mandibular body and across the jaw of 11.52 mm. There was a higher increase for females at
6 and 7 years many of 100.52 mm and 96.88 mm respectively in the overall growth of the jaw. Based
on these results it was concluded that the space for first and second permanent molars is reduced over
the years are very similar in females and males, the growth of the mandible and the mandibular body
were positive, slightly larger in females, the total length of the jaw also had increased over the years,
being significantly higher in females than in males, total length of the jaw also had increased over
the years,being significantly higher in females than in males; in general, females grew larger than the
structures studied in males and greater distance between the molars and the mandible.

Do metal brackets suffer physicochemical changes by the action of different toothpastes?
Objective: To evaluate the in vitro ionic degradation and slot base corrosion of metallic brackets subjected to brushing with dentifrices, through analysis of chemical composition by Energy Dispersive
Spectroscopy (EDS) and qualitative analysis by Scanning Electron Microscopy (SEM).Methods: 38
brackets were selected and randomly divided into 4 groups (n = 7). Two groups (n = 5) worked as
positive and negative controls. Simulated orthodontic braces were assembled using 0.019 x 0.025-in
stainless steel wires and elastomeric rings. The groups were divided according to surface treatment:
G1 (Máxima Proteção Anticáries®); G2 (Total 12®); G3 (Sensitive®); G4 (Branqueador®); Positive
control (artificial saliva) and Negative control (no treatment). 28 brushing cycles were performed and
evaluations were made before (T0) and after (T1) experiment. Results: The Wilcoxon test showed
no difference of Ti, Cr, Fe and Ni between groups. G2 presented reduction (p < 0.05) in Al. G3 and
G4 presented increase (p < 0.05) in Al. The SEM analysis showed increased characteristics indicative
of corrosion on groups G2, G3 and G4. Conclusion: The EDS analysis revealed that control groups
and G1 did not suffer chemical change. G2 presented degradation of Al. G3 and G4 suffered increase
of Al. The immersion in artificial saliva and the dentifrice Máxima Proteção Anticáries® did not alter
the surface polishing. The dentifrices Total 12®, Sensitive ® and Branqueador® altered the surface
polishing.

Craniofacial Features of Patients with Sickle Cell Anemia and Sickle Cell Trait
Objective: To identify the craniofacial characteristics of patients with sickle cell trait (SCT) and sickle
cell anemia (SCA) and to compare these measurements with normal subjects. Materials and Methods:
patients were evaluated in this study, which were divided into three groups, normal, SCA and SCT
(n=45). Lateral cephalometric radiographs were carried out, that were used to obtain angular and linear measurements of anatomical structures displayed. All markings and measurements were performed
by a single examiner. Results: The average ANB was increased in groups with SCA (5.47°) and SCT
(3.80°), indicating a tendency to class II. The mean SNA angle was 83° and 82.1° for SCA and SCT,
indicating a proper positioning of the jaw from the skull base. There was an interaction between the
factors group and sex for the variable SN.GoGn, with higher measures for men in the group SCA.
Conclusion: Patients with SCA and ACT exhibit characteristics of class II skeletal pattern, due to
mandibular retrusion. Most patients showed no compensatory maxillary expansion, which was determined by the normal jaw length and absence of maxillary protrusion.

Occlusal and Facial Features in Amerindians: Revisiting the role of genetics and environment.
Objective: To analyze facial and occlusal characteristics of three villages from the middle valley of
the Xingu River and compare them with two other villages previously published. The hypothesis
of genetic versus dietary influence on dentition and facial features was tested, through the analysis of
these populations. Methodology: The sample examined was composed of 351 individuals from villages Arara-Iriri (n=46), Arara-Laranjal (n=130), Assurini (n=87), Pat-krô (n=57) e Pikayaká (n=31).
Prevalence and descriptive differences in the outcomes frequency were compared using the chi-square
test or Fisher’s exact statistic. All the statistics were performed using two-tailed distribution at p≤
0.05. Results: We found a striking difference in occlusal patterns and face morphology between the
villages. The prevalence of malocclusion ranged from 66.7% to 33.8%. The malocclusion was more
prevalent in villages Pat-Kro (66.7%), Arara-Iriri (63%) and Assurini (60.9%), while the normal occlusion was more prevalent in villages Arara-Laranjal (66.2%, p <0.001). Conclusion: Ameridindias
do not present a unique dentofacial pattern, since the intergroups variability seems to be the rule, even
in groups from the same ethnicity. Our findings, supported in studies in the field of genetics, tooth
wear and feeding habits of these populations, refute the role of the environment as the primary etiological factor of dental malocclusion and facial morphology discrepancies.

Selective Alveolar Corticotomy In Intrusion Of Molars: Analysis Of Periodontal Clinical Parameters
Objective: To evaluate the impact of selective alveolar corticotomy associated with orthodontic intrusion on periodontal clinical parameters of extruded maxillary first molars. Materials and Methods: 14
individuals with extruded maxillary molars were randomly selected to undergo corticotomy as coadjuvant therapy for intrusion. Before and after intrusion the following periodontal clinical parameters
were evaluated: Probing depth, periodontal recession, clinical attachment level, keratinized mucosa
strip and gingival margin thickness. In addition, the quantity of intrusion obtained was measured.
The data obtained were statistically analyzed (Wilcoxon or Student’s-t test for paired samples). Results: after intrusion, a significant increase was observed in palatine periodontal recession (p = 0.034),
significant reduction in vestibular periodontal recession (p = 0.016), and in gain of attachment in the
vestibular region (p = 0.041) of the intruded molars. The remaining clinical parameters evaluated
underwent no statistically significant changes (p>0.05). In addition, intrusion of all the teeth was
obtained (mean 2.26 ± 0.52 mm). Conclusions: In the present study the absence of clinical compromise of the periodontal parameters could be observed, bearing in mind that the increase in palatine
periodontal recession does not lead to loss of attachment in this region; in addition to reduction in
vestibular periodontal recession for gain of attachment in this region, and obtainment of adequate
intrusion in a short period of time.

Effect of myofunctional therapy in the oral functions after orthognathic surgery
Objective: To investigate the effect of miofuncional therapy (MT) in orofacial functions of subjects
undergoing Orthognathic Surgery (OS). Methods: Twenty-two subjects were selected, 14 women
and 8 men, between 18-40 years old, 8 with Class II and 14 Class III skeletal malocclusion. The
subjects were divided into two groups, with MT (n = 12) and without MT (n = 10). The MT started
30 days after OS procedures weekly, totaling 10 sessions. The TM through exercices approched to
improve the sensitivity, tone and mobilitty orofacial thus starndards training of normal physiological breathing, chewing, swallowing and speaking. After three months of OS orofacial functions were
evaluated by Myofunctional Orofacial Protocol-MBGR, using the scores specified in the protocol
itself: respiration (scores 0-9), chewing (scores 0-10), swallowing (scores 0-50) and speech (scores
0-32); a higher value means a higher degree of modification. Comparisons between groups were performed using the Mann-Whitney test (α=0.05). Results: The group treated with MT showed lower
mean scores, in other words, best fit for the functions of breathing (p = 0.02) and swallowing (p <
0.01). Conclusion: MT improved the functions of breathing and swallowing for individuals undergoing OS, showing efficacy of speech therapy in these cases.

The effect of home bleaching on adhesion of orthodontic brackets
Objective: To evaluate the effect of at-home bleaching on shear bond strength (SBS) of brackets
bonded to enamel at 4 different time intervals after bleaching. Materials and Methods: Ninety extracted human premolars were randomly divided into 9 groups (n=10) according to the storage time
in artificial saliva (30 minutes, 24 hours, 14 and 21 days) before bonding brackets to bleached enamel.
Control group (unbleached) was stored in artificial saliva for 7 days. At-home bleaching was performed with 7.5% hydrogen peroxide which was applied to enamel for 1 hour daily for 21 days.
Brackets were bonded with conventional adhesive system and SBS testing was performed. The adhesive remnant index (ARI) was used to assess the amount of resin remaining on enamel surfaces after
debonding. SBS data were subjected to ANOVA and Tukey’s test. For the ARI, the Kruskal Wallis test was performed. Significance for all statistical tests was predetermined to be p<0.05. Results:
The SBS of unbleached group was significantly higher (p<0.05) than bleached groups (except group
bonding 30 minutes after at-home bleaching). Conclusions: The at-home bleaching decreased shear
bond strength (SBS) of brackets to enamel, except for group bonding 30 minutes after bleaching. SBS
returned to values close to those of unbleached enamel within 3 weeks following bleaching.

Factors related to orthodontic treatment time in adult patients
Orthodontic treatment of adult patients has a great variability in the time required for its completion.
Objective and methods: In order to evaluate factors influencing the duration of treatment in adults,
were examined 70 clinical cases with class I or II malocclusion, obtained from the initial examination
of 4700 records, collected in three experienced orthodontists clinics. The influence of the variables
collected in the documentation of patients on treatment time - dependent variable, was assessed by
multiple linear regression analysis, followed by the stepwise method at p <0.05. Results: The number
of months without being accompanied by faults (R2 = 14.4%, P = 0.0037) and the number of appliance breakages (R2 29.71%, p = 0.0001) had a significant influence on the variation of treatment
time. Other factors, such as initial canine relationship, the use of metal or ceramic brackets, orthodontic extractions included in the planning, age at start of treatment, the PAR index at the beginning
of treatment, the patient’s sex and facial pattern had no significant influence on treatment time (p>
0.05). The analysis of all factors allowed the prediction of only 54.33% of the variation in treatment
time. Conclusion: We conclude, therefore, that the duration of orthodontic treatment in adults, when
performed by experienced orthodontists, is mainly influenced by factors associated with the patient’s
collaboration. However, several factors not included in this study may contribute to variation in the
duration of orthodontic treatment.

Early intervention of anterior crossbite.
The anterior dental crossbite is defined as a malocclusion, resultant of a lingual position of the upper
anterior teeth relative to lower. The objective of this work is to report a clinical case of unitary anterior crossbite in 3 years old patient, in which was used an inclined plan to early intervention and bite
correction. It emphasize the importance of the study of etiological factors, allowing professionals to
act with the possibility of preventing a certain irregularity, outlining their treatment prognosis and
the stability of correction. Early treatment prevents future dentoalveolar’s complications, and fixed
appliances are preferred because they are independent of patient compliance to, treatment, and among
them, the inclined plane has proven clinically effective, as demonstrated in this case report.

Aim: To evaluate the in vivo color change of esthetic elastomers of four trademark. Material and
Methods: The brands Morelli, GAC, 3M Unitek and American Orthodontics were assessed in 20
adult patients. The elastomers were evaluated by patient and orthodontist, on the day of installation
and 30 days after exposition in the oral environment. A scoring staining system was compared by
Friedman test at the level of p<0.05. Results: there was a significant difference in the evaluation of the
elastomers pigmentation, after exposition to the oral cavity in all of the brands examined. Morelli elastomers showed the highest degree of staining, with median reaching the maximum value (3), while
the other brands median were 1.0 (p<0.01). It was noticed a great individual variability in the degree
of staining for all brands. Orthodontists and patients reported similar scores of staining. Conclusion:
Analysis of the four commercial brands of esthetic elastomers investigated showed an unpleasant staining perceived similarly by laypersons and orthodontists to all brands investigated. The staining was
more pronunced for Morelli elastomers.

Polypropylene membrane for alveolar ridge preservation in cases of dental extractions in
orthodontics: case report
Techniques and maneuvers for alveolar ridge preservation after tooth extraction become more common in dentistry in orthodontic treatment with extractions especially in patients with bone and gingival unfavorable characteristics, preserve tissue can determine aesthetic conditions favorable for orthodontic treatment. In this context the polypropylene membrane for preservation of alveolar ridge,
developed in Brazil, presents advantages over particulate bone grafts and / or collagen membranes as
reduced cost, simple surgical technique may be exposed in the oral environment. In the presented
case the patient was referred to the orthodontist for teeth removal 14 (I premolar right) and 24 (I left
premolar). The removal was done with the least possible trauma polypropylene membrane was placed
on the socket 2 mm by 2 mm by buccal and palatal suture held in the flaps without perforating the
membrane. After 7 days the suture and the membrane were removed and the patient was referred to
the orthodontist to continue orthodontic movement. Preserving vertically and horizontally alveolar
ridge provides more favorable conditions for orthodontic movement, thus it becomes important to
know the orthodontist techniques and resources for this purpose, and the polypropylene membrane
with all its advantages a great alternative.

children with hearing. 84 boys and girls 7-10 year old were examined in a school designed to treat
people with this deficiency. Results: 94.08% of schoolchildren showed any kind of malocclusion.
The sagittal relationship prevalence was: 59.5% class II; 29,8% class I; 10.7% class III. Overjet was
normal in 34.5% of the sample; 52.4% increased and 9.5% had top occlusion. Overbite was normal
in 23.3% of the sample; increased in 57.1% and and on top 9.5%. Transversal analysis showed 41.7%
with normal arches, 51.2% with atresia, 3.6% unilateral functional crossbite, 2.4% with true unilateral crossbite and 1.4% with dental crossbite. The presence of diastema was 23.8% and 54.8% dental
crowding. Conclusion: students with hearing impairment assessed had a high prevalence of malocclusion.

Lingual Orthodontics: Case report
Objective: To describe a case of lingual orthodontics and compare results of the final leveling phase
with those planned at setup model before the beginning of the treatment. Description of clinical
case: The patient characteristics were: permanent dentition, mesofacial biotype, Class I malocclusion, moderate crowding, tooth # 12 crossbite, mandibular incisors mildly tipped buccally and soft
tissue harmony. The treatment plan included interproximal reduction to align teeth and avoid buccal
tipping, so as to prevent any possible negative effect on soft tissue harmony. Plaster models were obtained, and the setup was built manually to evaluate whether planning was adequate. After plan confirmation, indirect bonding and customization of the brackets were prepared on the setup model. The
first phase of the treatment comprised interproximal teeth reduction and leveling with individualized
arch wires, both according to planned setup model. When the leveling phase was completed, dental
results were compared with the ideal setup model by intermolar and intercanine distances, overbite,
overjet, arch depth and occlusion analysis. Conclusions: Teeth position and occlusion at the end of
leveling phase were similar to those planned at setup model, which suggests that this may be a useful
tool for planning, indirect bonding and customization of both brackets and leveling arch wire in cases
of lingual orthodontics.

Esthetic perception of black spaces between maxillary central incisors by individuals of different
age groups
Objective: To evaluate the degree of perception of laypersons of different age groups with respect to
smile esthetics in cases involving black spaces between maxillary incisors. Materials and Methods:
Changes were made in a photograph of a smiling female patient, simulating various configurations of
black spaces between maxillary incisors. For this purpose an image manipulation Photoshop CS3 was
used. For evaluation black spaces of 0.5, 1.0, 1.5, 2.0, and 2.5 mm in size were created. After digital
manipulation, the photographs were printed on photographic paper, attached to a questionnaire, and
distributed among laypersons in the age groups of 15-19; 35-44, and 65-74. To evaluate the degree of
esthetics, a scale of attractiveness was used, in which a score of 0 would represent ‘’hardly attractive’’,
5 ‘’attractive’’ and 10 ‘’very attractive’’. Results: Results showed that the photographs without black
space and with black space of 2.5 mm were scored as the most and least attractive, respectively, by all
the age groups. The degree of perception of black spaces between maxillary incisors gradually diminished as the age of the groups increased (p<0.05). Conclusions: Black spaces have a negative repercussion on smile esthetics. The larger the black space, the less attractive the smile.

spring to incisors teeth verticalization (11/21). In the following session, a orthodontic round caliber
0.018” was adapted and the spring was removed. After space closure, the brackets were removed and a
upper removable device was adapted with a palatal expander and teeth stock - functional and aesthetic
space maintainer. The patient is in a preservation phase for subsequent exchange of removable appliance until the proper time for corrective treatment (orthodontic/implant/dentistry). In conclusion,
this case was considered successful in pediatric-orthodontic dentistry integrated treatment because
it allowed the restoration aesthetic- functional patient, improving self-esteem just preparing dental
arches for future rehabilitation.

Orthodontic traction of Impacted Upper Central Incisors: Case Report.
The impaction of permanent teeth is highly prevalent in our population. Its etiology is associated
with general and local factors. The eruption of these teeth there are consequences when occlusion
and involves anterior teeth also causes great disfigurement, which end up being related to psychological problems such as low self-esteem. Among the etiologic factors include: changes embryological
development of the tooth germ; pathologies such as supernumerary teeth and odontoma; mechanical factors, such as lack of space and alkalosis, chewing less intense and traumas. In these cases, early
diagnosis and appropriate treatment are important for better resolution of the problem from the point
of view of functional and aesthetic. Orthodontics associated with surgical procedures has achieved
satisfactory results in the treatment of impacted teeth. The purpose of this study is to report the case
of a nine year old with two incisors withheld because of odontoma in the anterior -superior maxilla.
We conducted rapid maxillary expansion, with subsequent surgical procedure for exposure and traction of impacted teeth, through the technique of collage button associated with a palatal bar modified
for traction and fixed orthodontic appliance.

Integrated treatment between dentistry and speech therapist in a clinical case of malocclusion
Objective: To describe the integrated dental treatment and speech therapy of a child presenting occlusal and functional alterations. Case Description: Patient YLC, female, 5-year-old, sought treatment because of diastema attributed to labial frenulum. On clinical examination, there was absence of
ischemia of the incisive papilla, 6 mm of diastema, open bite, tongue interposition and left posterior
cross bite. It was observed in radiographic images advanced rizolisis of 51/61 teeth and favorable positioning of the 11/21. Orofacial functions, tone, mobility and posture of the phonetic-articulators structures were evaluated following the Protocol Myofunctional Orofacial MBGR. It was found decreased
tone tongue, deviation in mouth closing, speech, chewing and swallowing alteration. Treatment plan:
Removable palatal expander and diastema monitoring. The cross bite was corrected after six months,
but in clenching the patient presented right deviation, interfering with mastication. Speech therapy
was instituted. Isotonic exercises was applied to correct the mouth opening and closing standard,
isometric exercises to adjust the tone of language, strategies for awareness tongue posture, and appropriate exercises for speech, mastication and swallowing. After two months there was improvement in
those aspects. Conclusion: The integrated care for the child promoted the reestablishment of occlusion and appropriate oral functions.

Uprighting second molars with the aid of mini-implants for prosthetic rehabilitation: Case report
The objective of this work was to evaluate the movement of molar uprighting in adult patient with
help of mini-implants for anchoring. The patient required prosthetic space recovery for installation of
implants on tooth 45, 46 and 36. The treatment plan was dental extraction of the tooth 48, followed
by installation of mini-implants in the region of the retromolar trigone and uprighting bilateral 37 and
47. The activation occurred every 15 days and the force employed was of 150 g. After seven months,
occurred the uprighting of 37 and 47 teeth and these were stabilized by a metal strap wire docked at
mini-implant until the respective buttons of the bands. It was concluded that the uprighting of molar
with the methodology described provided a faster and more efficient orthodontic treatment and can
reestablish enough space for prosthetic rehabilitation.

Comparative analysis of Scale of oral health outcomes for 5-year-old children (SOHO-5) and Early
Childhood Oral Health Impact Scale instruments
Objective: The aim of the present study was compare SOHO-5 and ECOHIS instruments for
evaluation of dental caries impact on 5-year-old children quality of life. The sample was comprised
by 121 children/parents randomly selected in Diamantina-MG. Children were submitted to oral
examination for caries assessment. Parents answered the ECOHIS and SOHO - 5p and children
answered the children’s version of the SOHO-5c. The comparative analysis was performed between
ECOHIS x SOHO-5p, SOHO-5c x SOHO-5p and ECOHIS x SOHO-5c for each item of the
instruments (pain, difficulty eating, talking, playing, sleeping, avoid smiling). Each instrument was
associated with caries. Statistical analyzes involved Kruskal -Wallis test, Mann -Whitney test and
Spearman correlation and the analysis of the area under the receiver operating curve. There was
significant correlation between SOHO-5p and ECOHIS (p<0.001). No significant correlation
was observed between SOHO-5c x SOHO-5p and SOHO-5c x ECOHIS (p>0.05). Significant
association was found between the instruments ECOHIS and SOHO-5p with caries (p<0.05). No
association was found between the SOHO-5c and caries (p>0.05). The analysis of the area under the
ROC curve showed that SOHO-5c, SOHO-5p and the ECOHIS discriminate children with and
without caries with a precision of 52%, 68% and 72% respectively. ECOHIS and SOHO-5p were
similar to each other and were associated with caries. The account of the children was different from
parents’ reports and was not able to discriminate between children with and without caries.

Assessment of Oral Health Care in Children with Diabetes Mellitus Type 1
Objective: This study evaluated the oral health care offered to children with diabetes mellitus type 1
(DM1) in the primary dentition. For that, it was selected at the Ambulatory of Diabetes from IPPMG/
UFRJ children with DM1 who were in the primary dentition. The guardians were interviewed
about oral hygiene, diet habits and dental treatment offered to the children. Oral examination was
performed to determine the dfm-t index. A total of 23 children aging between 2 and 6 (3.83±1.11)
years old composed the sample. In spite of 87% of the guardians have affirmed that the children’s oral
hygiene is performed and 61% have been oriented by the doctor to search for dental care, 40% of the
children has never been to dentist. From those who have visited the dentist, tooth pain and presence
of dental cavities were the most common reasons to look for treatment. The restorative treatment was
the dental procedure performed in the major of the children, reflecting on the dmf-t which varied
from 3 to 20 (11±5.8). Even with the possibility of free dental treatment next to place the children
have appointments regularly to the DM1 treatment, 40% of the guardians did not accept the dental
treatment offered. The oral health influences positively the general health of children with DM1 but
little attention has been given to promotion of oral health. It is necessary greater elucidation to the
guardians about the importance of oral care to promote oral health and improve the quality of life of
these children.

Performance of methods for detection of proximal caries lesions in primary molars - In vivo.
Objective: The aim of this clinical study was evaluate the performance of the visual method coded with
the Nyvad criteria, radiographic examination (BW) and laser induced fluorescence DIAGNOdent Pen
in detection of approximal caries lesions in primary molars. Forty-five children aged between 5 and 9
years who had primary molars with signs suggestive of the presence of caries or sound. The surfaces
(n=59) were evaluated clinically and coded according to Nyvad criteria, and DDPen. The radiographic
examination was performed only in those teeth scored with Nyvad criteria 2, 3, 5 or 6. Caries active
and/or discontinued surface were restored, and the lesions’s depth after cavity preparation was used
for validation. Sensitivity, specificity, accuracy and area under the ROC curve were calculated for
each method, considering lesions in enamel and dentin ( D1 ) and only dentin lesions ( D2 ). Visual
examination with the Nyvad criteria showed the highest specificity (0.95 in D1 and D2 in 0.93 ),
accuracy ( 0.94 in D1 and D2 ), and area under the ROC curve ( 0.90 and 0.95 in D1 to D2 ), while
DDPen showed the highest sensitivity ( 0.97 and 0.96 in D1 to D2). Although the performance of
radiographic examination and DDpen have been good, the use of visual examination with NYVAD
criteria was sufficient for the diagnosis of interproximal caries lesions in primary molars.

Effect of nanosized sodium trimetaphosphate added to low-fluoride dentifrices on enamel
demineralization in vitro
Objective: To assess the effect of the concentration and particle size of sodium trimetaphosphate
(TMP) on enamel demineralization when associated to low-fluoride dentifrices in vitro. Methodology:
Bovine enamel blocks (4x4 mm) were analyzed by surface hardness (SH) and randomly divided into
12 groups (n=12/group) according to the dentifrices tested: Placebo (P), 500 µg F/g (500), 500 µg F/g
associated to TMP at concentrations of 0.25, 0.5 and 3.0% with particles of conventional size (TMPc),
or crushed in a ball mill for 24h (TMP24) or 48h (TMP48), besides a positive control (1,100 µg F/g).
Blocks were submitted to 5 pH cycles (37 ºC) and treated twice/day (1 min) with slurries of the
above-mentioned dentifrices. After the determination of final SH, the percentage of SH loss (%SHL)
was calculated and data were submitted to ANOVA and Student-Newman-Keuls’ test (p<0.05).
Results: A dose-response relationship was observed between %SHL and fluoride concentration in
the dentifrices without TMP. However, the lowest values of %SHL were observed for 500/TMPc
3.0%, 500/TMP24 0.5% and 500/TMP 48 0.25%, without significant differences among them.
Conclusions: The supplementation of dentifrices containing 500 µg F/g with TMP leads to a more
effective reduction of %SHL when compared with a 1,100 µg F/g dentifrice. Thiseffectisenhancedbythe

In situ effect of Recaldent® containing chewing gum at different stages of human enamel erosion
Objective: This study evaluated the in situ effect of an chewing gum containing Recaldent® in
different stages of dental erosion. Methods: Studied groups: GWR Trident Total® (with Recaldent®)
GNR Trident Fresh® (no Recaldent®) and GC control (no gum). In the 1st step 72 human enamel
blocks were selected by the hardness and were eroded in vitro (Coke®, 3 min - hardness evaluation).
Twelve volunteers wore intraoral palatal devices for 24h in 3 crossover phases. In GWR and GNR
volunteers chewed the gum for 30 minutes, 4 times in 24h. The hardness was assessed after 2 and 24h
to calculate the percentage of surface hardness recovery. In the 2nd step (3 crossover phases of 7 days)
48 healthy blocks were randomized between groups and eight volunteers wore palatal devices which
were immersed in 150ml of Coke® for 5 min, followed by a chewing gum for 30 min in GWR and
GNR, 4x/day. Enamel alterations were measured by profilometry and analyzed by ANOVA/Tukey.
Results: In the 1st step GWR (2h/50.0%; 24h/95.9%) showed higher hardness recovery compared to
GNR (2h/30.0%; 24h/71.1%) and GC (2h/15.7%; 24h/40.9%) (p<0.05). In the 2nd step GWR (5.2
± 2.8 µm) and CNR (3.8 ± 1.5 µm) significantly reduced tooth wear compared to GC (6.8 ± 3.5 µm),
with no differences between the chewing gums (p>0.05). Conclusions: Recaldent® chewing gum
increases remineralization of erosive lesions, but it is not able to enhance enamel protection against
the erosive challenge.

Integration of Pediatric Dentistry and Orthodontics in Dentistry courses in Brazil
Objective: The present study aimed to diagnose the existence or not of integration between
Orthodontics and Pediatric Dentistry in the 203 undergraduate courses in dentistry throughout
Brazil, as well as the opinion and importance given by the professors and coordinators concerning the
integration of the two disciplines, by means of a semi-structured questionnaire sent by both email and
Survey Monkey. The response rate was of 30.54% in relation to the total number of undergraduate
courses. The dentistry disciplines were integrated in 75.8% of the undergraduate courses, whether at
public or private universities, and were offered mostly during the seventh and eighth periods of the
course. This study showed that 80.6% of the surveyed individuals considered the integration possible
and advantageous for the students’ education, while 95.2% of the surveyed individuals considered this
integration to be important at children’s dental clinics; 47.05% of the surveyed individuals considered
the major hindrance to integration to be related to the professors, while 27.45% considered this
hindrance to be related to the institutions themselves; 86.67% of the institutions from the Southeast
region of Brazil reported no integration between the disciplines. This finding was statistically
significant when compared to integrated education in the other surveyed regions throughout Brazil.

Crescer Sorrindo/UERJ Project: integrating teaching, research and extension for 12 years
Abstract: Children can be affected by various dental problems such as dental caries, malocclusion
and dental trauma. These dental problems can have a negative impact on children’s lives and on their
families’. For that reason, it is important to prevent them. Nevertheless, when they occur, they need to
be promptly addressed in order to limit impairment on children´s quality of life. “Crescer Sorrindo”
project is an excellent opportunity for integrating theory and practice within pediatric dentistry. Due
to its multidisciplinary focus, the project enables students and teachers to obtain a holistic view of the
pediatric patient. “Crescer Sorrindo” has been developed by the School of Dentistry/UERJ, at Piquet
Carneiro Polyclinic, since 2001. The aim of the project is to promote the oral health of children up
to 11 years of age through educational, preventive and restorative activities and to emphasize dental
care for preschoolers. In 12 years, approximately 530 preschoolers have received dental care and more
than 750 undergraduate and 150 graduate pediatric dentistry students have been involved. In addition,
the project carries out scientific research in the field of children’s oral health. Thus, the “Crescer
Sorrindo” project has been promoting children´s oral health, for the last 12 years, by integrating
teaching, research and extension.

aspects about the children dental caries experience. A sample of 465 children were assigned into three
groups: Babies whose mothers joined the program when still pregnant (n=50); Babies that joined the
program during the first year of life (n=230); and Children that joined the program between 13 and 18
months (n=185). The Chi-Square and Kruskal-Walis tests (IC95%) assessed the relationship between
the variables. It was observed that there was an association between group and dental caries (p<0.001),
being the smaller prevalence for G0 and G1. Similarly, it was found association between the children’s
age when joining the program with assiduity, cariogenic diet, oral night hygiene, duration of night
feeding and parents’ educational level, children’s behavior through out the treatment, at home or at
the office (p<0.001). Low socio-economic background (p>0.05) and day oral hygiene (p=0.214) were
common variables in the groups with 99% of occurrence. Assiduity, night oral hygiene presence
and parents’ level of education variables were protection factors for dental caries. Cariogenic diet and
night feeding were determinant factors for dental caries. It was concluded that in order to promote
children’s oral health it is essential that children join the program earlier in life, assiduity and the
children and parents’ positive behavior.

Pulpal response after using the low-level laser therapy on pulpotomy of human primary teeth
Objective: The aim of this study was to evaluate through clinical, radiographic and histological
analyses the effects ofLow-Level Laser therapy (LLLT)on pulpal response of human primary teeth
after pulpotomy. Twenty mandibular primary molars of children aged between 6 and 9 years were
selected. The teeth were randomly divided into the following groups: Buckley’s Formocresol
(diluted 1: 5) (GI), Calcium Hydroxide (GII), LLLT + Zinc Oxide and (GIII), and LLLT + Calcium
Hydroxide (GIV), and treated by the pulpotomy technique. The clinical and radiographic evaluations
were performed at 3 and 6 post-operative months. The teeth in the normal exfoliation period were
extracted and processed for histological analysis and assessed through a score system. The clinical
and radiographic results did not show statistically significant difference among groups (p>0.05). The
statistical analysis of the histological assessment revealed statistically significant difference for pulpal
inflammation, with the least degree of pulpal inflammation for group GIV. The group GII showed a
higher rate of formation of mineralized tissue barrier, odontoblastic layer and dense collagen fibers.
The group GI showed higher incidence of internal resorption. The results obtained indicated that the
group GIV showed more satisfactory effects compared to other groups. Therefore, it is suggested that
Low-Level Laser therapy with Calcium Hydroxide can be considered as an alternative technique for
the pulpotomy of human primary teeth.

Bottle feeding and malocclusion in permanent dentition: systematic review and meta-analysis
Objective: To search for scientific evidence on the association between a history of breastfeeding
compared to bottle feeding and risk of malocclusion in the permanent dentition. Methods: An
electronic search was performed in seven databases with no restrictions regarding language or year
of publication. Data were extracted on type of feeding habits (breastfeeding vs. bottle feeding) and
duration of breastfeeding (< 6 months vs. ≥ 6 months). Relative risk measures and confidence intervals
were described. Results: The systematic review included four studies (3 cross-sectional and 1 casecontrol). When malocclusion was evaluated using clinical data, bottle feeding was associated to
increased mean protrusion of the maxillary and mandibular incisors as well as mean inclination of the
maxillary incisors (OR: 1.464; 95% CI: 1.091-1.965). However, facial profile was not associated with
the duration of breast feeding (OR: 0.885; 95% CI: 0.462-1.695). However, there were few studies
and substantial heterogeneity among them. Conclusions: The scientific evidence suggests a weak
association between bottle feeding and malocclusion in the permanent dentition. More prospective
cohort studies are needed to confirm the evidence.

Marginal adaptation between glass fiber post and primary root dentin after 6 month degradation
Objective: The aim of this study was to evaluate the influence of filling materials andcleaning agents
in marginal adaptation between glass fiber post and root canaldentin after 6 month degradation. Roots
of primary bovine teeth wereendodontically treated and assigned into groups: Control (no material
- C);Calen® + Zinc Oxide (CZO); Vitapex® (V); Calcipex II® (CP). After 7 days, fillingmaterials
were removed and the roots were subdivided according the groups(n=10): No cleaning (NC); 70%
Ethanol (E); Tergenform® (T). Glass fiber posts were luted using resin cement RelyXTMARC after
acid etching, rinsing and application of adhesive system. Specimens were sectioned (±1 mm) and
water storage for 6 month. After this period, they were polished and replicas were made. Images
obtained by scanning electron microscopy were measured usingthe software Image J 1.45 to calculate
the gap formation percentage (%G). Thedata were submitted to two-way ANOVA and Tukey’s test
(α=5%). Interaction was not observed between the studied factors (p<0.05). Significant difference
was observed for filling materials (p<0.01) and cleaning agents (p<0.05). COZ showed the lowest
%G (41.90±21.45), significantly different from C(62.23±19.59). E showed %G (60.04±26.71)
significantly different from T(46.84±22.77). It could be concluded that filling materials and cleaning
agents influenced the marginal adaptation of glass fiber post to root dentin after 6 month degradation.

Bond strenght of hight-viscosity glass ionomer cement with clorhexidine diacetate according to
substrate and time.
Objective: This study evaluated the long-term influence of the addition of chlorhexidinediacetate
(CHX) at different concentrations to a high-viscosity GIC on its adhesion to sound and cariesaffected dentin. Sixty third molars were divided into 6 groups (n = 10) according to the condition of
the substrate (sound and caries-affected dentine) and concentration of CHX added to the GIC (GIC
+ CHX 1% and 2% CHX), and GIC without CHX was used as control. Dentin flat surfaces were
produced and half of them was subjected to artificial induction of caries. In each dentin surface of two
specimens of the same material (1 mm in diameter and 1 mm in height) was made. They were kept
at 37 °C with 100% humidity for 24 hours or immersed in distilled water for 6 months and tested
for microshear. Bond strength data were submitted to ANOVA and Tukey’s test (α= 0.05). In sound
dentin, GIC and GIC + CHX 1 % bond strength was statistically similar and higher than the GIC
+ CHX 2 % and there was no significant difference between immediate and six months analysis. In
caries-affected dentin, GIC and GIC + CHX 1% showed bond strength statistically superior to GIC
+ CHX 2% in the immediate analysis. At six months analysis there was no difference between the
groups, and GIC + CHX 2% was the only group in which bond strength didn’t reduce. The addition
of CHX at 2% decreased GIC/dentin bond strenght, but was able to prevent bond degradation after
six months.

Association between iron deficiency anaemia and severe early childhood caries - a case report
Objective: The aim of this study was to present a clinical case of a 3 years and 10 months old patient
with severe anemia associated with severe early childhood caries. The patient had low hemoglobin
levels (7.70 g / dl), ferritin (10.5 ng / dl) and serum iron (16 mg / dl), low hematocrit (25.9 %), and
impaired growth and delayed neuro-psycho-motor development. He was admitted to the University
Hospital of the Federal University of Santa Catarina, which received blood transfusion, antibiotics
and iron supplements. It was performed the extraction of all 20 root fragments on 4 different days,
under intravenous sedation with a combination of midazolam and ketamine. The discharge from the
hospital occurred after 20 days of hospitalization, when hemoglobin levels (10.80 g / dl), ferritin (44.5
ng / dl) and serum iron (30 mg / dl) were normal and the hematocrit equal to 34.2%. Treatment of
severe early childhood caries should occur as soon as possible, because the consequences of this disease
can affect significantly the overall health of the patient.

Carbonic anhydrase VI in saliva and plaque: a literature review
Abstract: Carbonic anhydrase VI (CA VI) is the only way of isoenzyme which can be secreted into
the saliva in order to provide a higher buffering capacity, and promote the retention of HCO3- level
in salivary glands. The high pH of the saliva would be required to maintain the appropriate medium
for the multiplicity of enzymes that are present, playing a remarkable role in protecting teeth against
tooth decay. This literature review aimed to discuss the mechanisms by which the CA VI in saliva and
biofilm acts in the buffering of acids present in the oral environment as well as the scientific evidence
on the relationship between the expression/activity of CA VI in saliva or plaque and caries experience.
The buffer effect of isoenzyme derives from the fact that CA VI catalyze the reversible reaction of
carbon dioxide in the reaction CO2 + H2O ↔ H + + HCO3-. Furthermore, the CA VI is adsorbed
on the tooth surface remaining enzymatically active. The analysis of the literature shows conflicting
results between the concentration of CA VI in saliva/plaque and caries experience. Furthermore,
there is evidence that a high concentration of CA VI saliva/biofilm may not necessarily mean that all
isoenzyme is active and thus capable of neutralizing the acid after a cariogenic challenge. There are
no reports on the possible relationship between the concentration and activity of AC VI in saliva and
dental plaque.

Appliance space maintainer glued: an alternative to early loss of deciduous teeth - Clinical Case
Report
Abstract: The early loss of primary teeth can cause a lot of harm, leaving sequelae that unbalance physiology of the oral cavity.The space maintainers are devices that can be used when a primary
tooth is lost prematurely in order to preserve the integrity of the occlusion, keep teeth involved in
their respective positions, to preserve space resulting from the premature loss of deciduous teeth and
allow the permanent tooth erupcione in normal position. The following work aims to present the
case of a 7 year old, male white, convex profile, mixed dentition, Class I molar relationship, whose
chief complaint was “stuck tooth” (according to information gathered). On clinical examination,
there was an open cavity in the second lower right deciduous molar (85) and fistula. The element
has undergone endodontic treatment, having unsatisfactory biological response. We opted for the
element extraction and subsequent installation of a space maintainer appliance glued (AMEC), to
wait for the eruption of permanent fixture. The maintainer of this selection was made on the basis
of their properties, because it has advantages such as low cost, ease of preparation, good resistance,
easy to clean and does not require laboratory phase and is indicated in cases of early loss of a single
element dental later. According to the established schedule for the case in question, was performed
prior to extraction molding for obtaining model and fabrication of orthodontic wire loop with 0.7.
To install the maintainer etching was done with 37% phosphoric acid in the vestibular region 46 of
the element 84 and, after 15 seconds acid was removed by washing with water while application of the
product, then application was made Single Bond and curing light for 20 seconds, then by inserting the
composite Filtek Z250 buccal teeth mentioned above, and subsequently positioning the bent wire on
the resin and curing for 40 seconds. The unit should be kept until the eruption of the tooth successor.
Thus, it can be concluded that the AMEC can be a viable option for cases of early loss of deciduous
molars and can obtain satisfactory results and success.

Application of resin-based materials as a preventive measure for eroded enamel, subjected to
erosive challenge - in vitro study.
Objective: The aim of this study was to evaluate the effect of resin-based materials application on
enamel with initial erosion lesion on the prevention of dental wear. The application of materials was
performed with and without prior enamel surface conditioning. The bovine enamel blocks were
immersed in HCl 0. 01 M, pH 2.3 per 30 seconds for formation of the initial erosion lesion. Then
the blocks were random divided in 9 groups according to the material applied (n=12): EC-control
without treatment, EH-sealant Helioseal Clear®, EA-self-etch adhesive Adhese®, ET-conventional
adhesive Tetric N-bond®, EI-infiltrant Icon®, EHs, EAs, ETs groups received the same materials
without surface conditioning. After the treatments the specimens were immersed in HCl for 2 min,
followed by immersion in artificial saliva for 120 min, 4xdays, during 5 days (erosive cycling). Analysis
of enamel wear and material thickness were conducted using perfilometry and the results submitted
to Kruskal-Wallis and Dunn test (p>0.05). The groups EH, EA, EI, ETs and EIs did not show enamel
alterations, being effective in inhibiting erosion progression. Based on the results of this study, it
is concluded that the application of pits and fissure sealant and infiltrant (regardless of the surface
condition) on eroded enamel was effective in inhibit the progression of dental erosion.

Arthrogryposis multiplex congenita associated to Multiple Pterygium Syndrome: case report
Abstract: Arthrogryposis multiplex congenita associated to Multiple Pterygium Syndrome is a rare,
autosomal recessive disease characterized by nonprogressive articular contractures and skinfolds. It
causes movement limitation, stiffness and periarticular thickening. The aim of this study is to describe a
case report of a patient with this condition assisted at Araraquara Dental School – UNESP. D.R.S.N.,
male, 10 years old showed joints distortion of upper and lower limbs and of the hip, limitation of
secondary movement, muscle weakness, postural problems and short stature. The facial characteristics
include: convex profile, vertical growth, elongation of the lower third, retruded chin and smile line
inverted. During clinical exam, it was observed interincisaldiastema, anterior open bite, atypical
swallowing with lingual inter- position, severe maxillary atresia, mouth breathing, limited mouth
opening and teeth crowding. The observed modifications in face and in oral cavity may hamper
oral hygiene and dental treatment. The extensive esthetic and functional committed emphasize the
importance of an early transdisciplinary approach in order to improve life quality of this patients. Very
little is known about facial-cranium-dental peculiarities of this condition, which justifies its study.

Association between different types of malocclusion and impact in quality of life of preschool
children
Objective: The aim of the present study was to evaluate the association between different types of
malocclusion and impact in quality of life among preschool children and their families. Methods: A
population-based cross-sectional study was carried out with 451 children between three and five years
of age. A clinical exam was performed for the evaluation of malocclusion: anterior and posterior open
bite, anterior and posterior crossbite and increased overjet and overbite (>3 mm). Dental caries and
traumatic dental injury was evaluated as possible confounding variables. Parents/caregivers answered
the Child Impact Section and Family Impact Section of the Early Childhood Oral Health Impact Scale
(ECOHIS) for the assessment of Oral Health-Related Quality of Life (OHRQoL) and a questionnaire
on socioeconomic and demographic characteristics. Data analysis involved descriptive statistics, the
chi-square test, Mann-Whitney test and hierarchically adjusted Poisson regression models. Results:
The prevalence of malocclusion was 28.4%. The most frequent conditions were posterior crossbite
(20.4%), anterior open bite (9.5%) and increased overjet (8.4%). A significant association was found
between the anterior open bite and OHRQoL in terms of impact on both the children and family
(p<.001). The adjusted analysis confirmed the association between anterior open bite and a negative
impact on quality of life (RR = 2.55; 95% CI: 1.87 to 3.47; p <.001). Conclusion: Anterior open bite
was associated with a negative impact in the quality of life of preschoolers.

Evaluation of tubular density and hardness in primary dentin
Objective: Based on the difficulty for acquisition human teeth for research, the possibility of using
more fragments of the same specimen would be an option to reduce the total number of teeth. The
aim of the present study was to evaluate properties of surface hardness and tubule density contiguous
surfaces of primary molars, in order to enable the use of parts of the same tooth for in vitro studies.
Ten first primary molar were sectioned perpendicular to the long axis, with double face diamond disc,
in occlusal third. Resulting in a top and bottom substrates. The surface hardness was measured with
Knoop (25g/5sec) indenter and the density of dentinal tubules was evaluated at 100x magnification
in confocal laser microscopy. Two trained examiners had analyzed the images. The mean (± standard
deviation) of superficial hardness were 49.63 (± 5.65) and 51.11 (± 9.04) for the upper and lower
portions, respectively. The mean tubular density (± standard deviation) of dentinal tubules in the
contiguous surfaces were 33,181.71 (± 7,022.85) for the superior portion and 27,664.22 (± 6,620.83)
for the inferior. It can be concluded that there is no difference between the values of surface hardness
and tubule density and thus contiguous surfaces of the same tooth could be used in in vitro studies.

Evaluation of masticatory performance and bite force in children and adolescents with
temporomandibular dysfunction
Objective: Temporomandibular dysfunction (TMD) involves changes in the structure and function
of the masticatory muscles and temporomandibular joints. Thus, the aim of this study was to evaluate
the masticatory performance (MP) and bite force (BF) in TMD subjects. TMD group comprised 50
subjects (age 10.94 ±2.02 years) and 50 subjects comprised the control group (10.8 ±2.13), matched for
gender, stage of dentition and orthodontic treatment need. MP was evaluated by the individual’s ability
to comminute an artificial test food in order to determine median particle size (X50) and distribution
of particles in the different sieves (“b”). BF was determined using a digital gnatodynamometer with
fork strength of 10 mm. TMD was evaluated using the Research Diagnosis Criteria. The results were
submitted to descriptive statistics, Shapiro Wilk test, “t” test, Mann Whitney and Wilcoxon. TMD
group median values (interquartile range) for X50 and “b” were 4.68 (2.09) and 2.20 (0.44); control
group values were 4.96 (2.16) and 2.10 (0.53), with no statistical difference between the groups. The
mean values (±SD) for BF were 355.60N (±86.12) and 345.18N (±111.42) for TMD and control
groups, respectively. There was also no significant difference between groups for BF. In conclusion,
the presence of TMD did not alter the masticatory parameters evaluated in the sample studied.

Evaluation of the relationship between the bite force and body mass index in young children: a
preliminary study
Objective: Little is known about the influence of masticatory function on nutritional status in children,
but it is assumed to be of importance. Thus, the aim of this preliminary study was to evaluate the
relationship between maximum bite force (BF) and body mass index (BMI) in 39 children aged 7-8
years (7.42 y ± 0.49), in the early mixed dentition. BF was measured using a gnathodynamometer digital
fork 10mm thick, in the left and right sides. Occlusion was evaluated using the Index of Orthodontic
Treatment Need (IOTN). Data were analyzed using descriptive statistics, Komolgorov-Smirnov test
and multiple linear regression to determine the relationship between BMI and the studied independent
variables: age, gender, IOTN scores and right and left BF. The mean right BF was 291.65 N (±99.62)
and mean left BF was 295.26 N (±109.01), with no significant difference between them. There was
no significant relationship between BMI and the variables under study. It was concluded that there
was no relationship between maximum BF and body mass index in the studied sample, and future
studies in a larger number of subjects are needed to determine the influence of masticatory function
on nutritional status in children.

Roughness evaluation of resin-based materials after polishing and chemical degradation
Objective: This study evaluated the influence of polishing systems and chemical degradation on
surface roughness (SR) of composites. 72 samples (7 mm diameter x 2 mm thick) were prepared
and randomly divided into 8 groups (n=9) in accordance with polishers Soflex (3M/ESPE) and Jiffy
(Ultradent); composites (Filtek Z350XT and Vitalescense); and degradation solution (coffee (CF) and
artificial saliva (AS)-control). After 24h at 37°C, samples were polished and initial SR was measured
(Ra). Then, each sample was immersed in 4 mL of staining solution (CF: for 15 min, three times a
day for 14 days). After that, final SR was measured and obtained ΔRa values. Data normality was
verified by Kolmogorov-Smirnov test (p>0.05) and submitted to tree way ANOVA and Tukey test
(5%). There were significant interaction between composites and polishers (p<0.001) and CF and
AS showed no effect on RS. Independent of solutions, Vitalescence showed no significant change in
RS when polished with Soflex (ΔRa=-0.05) and Jiffy (ΔRa=-0.09). However, Z350 showed greater
variation in RS for Jiffy (ΔRa=-0.25) compared with SofLex (ΔRa=-0.01). After degradation, SofLex
did not promote variations in SR for composites. However, Jiffy promoted smaller variations in SR for
Vitlescence (ΔRa=-0.09) than Z350 (ΔRa=-0.25). In conclusion, the solutions did not affect the SR
of composites. After degradation, Z350 polished with Jiffy showed decrease in SR, and composites
polished with SofLex showed SR maintenance.

apices and removing the root and coronal pulp, an orifice of 1.5 mm diameter x 2 mm depth was
made in the buccal face of the teeth for insertion of the cements and later application of ultrasound.
After filling the space left in coronal and root pulp with a thermo-conductor paste, a thermistor was
inserted through the root canal to the pulp chamber for temperature rise. Ultrasound was applied
to the cements for 45 seconds and photopolymerisation, if needed, for 40 seconds. Data were found
to be normal, and linear regression tests, Pearson’s correlation, ANOVA and Student t-test were
used for analysis. Results: The results showed that application of ultrasound to conventional and
resin-modified glass Ionomer cements for 45 seconds increases the pulp chamber temperature by
0.07oC/s and 0.06oC/s, respectively, at a 95% confidence interval. Conclusion: One can conclude
that the increased temperature found in the pulp chamber as a result of ultrasound application is safe
for clinical use.

Evaluation of oral functions of children with asthma using the Nordic Orofacial Test-Screening
Objective: This study aimed to evaluate the oral functions of children with asthma using the
NordicOrofacial Test- Screening ( NOT- S ) protocol.Methods: Forty children with asthma (19
♂, 21♀) and forty-two without asthma (19 ♂, 23♀), aged 7-9 yr-old, were selected from specialized
clinic and public schools of Piracicaba/SP, respectively. The Brazilian Portuguese version of NOT-S
was applied by a trained examiner by interview and clinical evaluation. The signs and symptoms
of sleep bruxism and malocclusion (Index of Orthodontic Treatment Need) were also evaluated.
Descriptive statistics, bivariate and multivariate analysis were used for data analysis, considering the
level of significance of α = 0.05.Results: The NOT-S total scores ranged from 0 to 8; scores 3 and
2 were the most frequent observed in groups with (30.0%) and without asthma (33.3%). Group
with asthma presented higher NOT-S total and NOT-S interview scores than those without asthma
(p<0.05). Asthmatic children were approximately three times more likely to report impaired sensory
function than children without asthma (p<0.05).Conclusion: The presence of asthma was associated
with reports of impairment of sensory functions and presence of oral habits, as well as with clinical
signs of respiratory dysfunction.

Evaluation of physico-chemical properties of filling materials used in primary teeth
Objective: The aim of the study was to evaluate the OH- release and flow of filling materials used
in primary teeth. For the first analysis, 60 bovine primary teeth were endodontically prepared and
filled according to the groups (n=10): Control (without material) (C), Zinc Oxide Eugenol (ZOE),
CalenÒ (CA), CA+OZ (CAOZ), CA+Iodofórmio (CAI), VitapexÒ (V). Teeth were immersed in
deionized water and the pH was measured at 1 hour, 1, 7, 15 and 30 days. For flow analysis was used
0.05 ml of the materials placed on glass plates and pressed by another plate associated with 100g
weight (ISO 6786, ANSI/ADA, nº57). The diameters were measured with a digital caliper. Data were
analyzed by factorial ANOVA, ANOVA and Tukey tests (α=0.05). It was observed that OH- release
in 1 hour showed no significant difference among groups (p>0.05). In one day, CA released more
OH- and remained constant for 7, 15 and 30 days (p>0.05). The OH- release of CAOZ remained
constant for all times and lower than all other materials. V released more OH- in 30 days. For the flow
analysis, it was observed significant difference among materials studied (p<0.0001). Higher flow rate
was observed for CA (21.28 ± 0.83), V (13.13 ± 0.19), CAI (10.57 ± 0.56), OZE (9.06 ± 0.49) and
CAOZ (6.97 ±.26). It was concluded that among the materials studied, CalenÒ showed the greatest
OH- release and higher flow ability compared to other materials.

Evaluation of brightness composites submitted to different polishing systems after chemical
degradation
Objective: To evaluate the influence of staining in the glow of composites after polishing. Methodology:
Seventy-two cylindrical samples (7x2mm) were made from Filtek Z350XT and Vitlescense composites.
After 24h at 37 ° C, there were polished with Soflex systems (3M) and Jiffy (Ultradent) and randomly
assigned into 8 groups (n = 9) according to the composite, polishing and staining solution [Coffee (CF)
and saliva artificial (SA)]. Initial brightness measurements were performed. Then, each sample was
immersed in 4 mL of CF for 15 min, 3x daily for 14 days. After, the brightness was measured again,
allowing the calculation of variation (Δbrightness). The data were submitted to Kolmogorov-Smirnov
tests, ANOVA factors 3 and Holmom-Sidak test (p<0,05). Results: There was significant interaction
between restorative material and polishing system (p=0.007). Regardless of the solutions presented
no significant ΔbrightnessVitlescence when polished with SL (3.80) and Jiffy (4.68). However, for
Δbrightness Z350 was higher with SL (10.32) than with Jiffy (5.85). After degradation, regardless of
polishers, Vitlescence showed no significant Δbrightness in CF and SA; already Z350 Δbrightness
in SA showed lower (6.14) than in CF (10.03). Conclusion: After degradation in CF, Z350 showed
higher Δbrightness when polished by SL; Vitlescence hasn’t presented Δbrightness. Therefore, in this
study the brightness of the composite was dependent on the solution, the material and the polishing
system.

In vitro fluoride release analysis of fluoride varnishes in different solutions
Objective: The aim of this study was to analyze the fluoride ions (F) release in vitro of 3 fluoride
varnishes submitted to demineralization (DES) and remineralization (RE) solutions, as a function
of time. For this, it was used polyester strips that received a standardized thin layer of varnishes.
The procedure was performed by a trained and calibrated researcher. The specimens were randomly
divided into three groups (n=5): Va (Vanish™-NaF varnish with 5% Tri-Calcium Phosphate), DR
(Duraflur -varnish 5% NaF) and DP (Duraphat®-varnish 5% NaF) and 2 solutions: DES and RE. The
specimens were individually immersed in 10 mL of each solution for 1, 3, 7, 24, 48, 72 and 120 hours,
and changed in pre-established times. The determination of F release in the solutions was performed
in duplicate, using a potentiometer (Orion Expandable Ion Analyzer 940 EA), which was expressed
in mV and converted into ppm F. Data were submitted to ANOVA factorial and Tukey tests (α=0.05).
It was not observed significant interaction among the studied factors: material, time and solutions
(p>0.05). VA (0.693) released more F when compared to DR (0.624) and DP (0.565) (p<0.05). The
highest concentration of F was observed in 72 (0.955) hours, with a significant difference for all times
(p<0.05). Regarding solutions, the highest fluoride release it was observed for DES compared to
RE. It could be concluded that the fluoride varnishes showed different fluoride release patterns, with
highest release in 72 hours and for demineralization solution.

Early Childhood Caries and Systemic Health
Objective: To discuss about early childhood caries (ECC) and systemic health, presenting data analysis
from two studies in children under 71 months that showed association of markers of nutritional deficits
and markers of chronic diseases with ECC. The first study was a retrospective cohort study with 625
children in Sao Luis, which showed through a hierarchical approach that low height/age ( p = 0.019 ),
and lower levels of hemoglobin ( p < 0.000 ), albumin ( p = 0.016 ) and zinc (p =.052 ) were associated
with ECC. In the second study, using data from NHANES III (1988-1994), through Poisson
regression analysis adjusting for confounders (ethnicity, gender, body mass index and Health Eating
Index ), it was showed that a greater number of caries in children seems associated with markers of
chronic diseases such as elevated C-reactive protein levels (PR 2: 09 IC 1.3, 3.2) and insulin resistance
(PR 1.7 CI 1.1, 3.1), which are markers of cardiovascular diseases and type II diabetes, respectively.
The results of these studies suggest that caries severity in childhood may be a predictor of the presence
of more serious systemic conditions.

Bullying, Pediatric Dentistry and Orthodontics: case report
Objective: The term bullying can be defined by the act of assaulting, stalking, or exclude someone
for a time and began to be researched in the 1990s, because the intensity of events related. This study
aims to report the clinical case of a patient 6 years old, male, reporting episode of bullying in school,
attributed to the positioning of the anterior teeth. The diagnosis and treatment plan were developed by
professional pediatric dentistry and orthodontics together. After the clinical pediatric dentistry, began
orthodontic treatment, with monitoring conducted by booth professionals. After the first results,
the patient reported changes in the behavior of classmates without the involvement of “mocking “
regarding their appearance and smile. Parents emphasized the positive change in school and daily life
of the child. After these initial changes, the patient began to smile more often and express himself
more naturally. Observing the positive reactions, we conclude that a child’s behavior may be related
to the appearance of their teeth and their personal relationships, especially in the school environment.
This case draws attention to the importance of pediatric dentistry and orthodontists, acting together,
to provide a broader treatment to the child, allowing a better quality of life.

Comparison of enamel microhardness of primary teeth of cerebral palsy and normorreactive
children
Objective: To compare in vitro the enamel microhardness of anterior and posterior primary teeth of
normorreactive children (NR) and children with cerebral palsy (CP). Methodology: The sample was
consisted of 58 exfoliated/extracted primary teeth of NR and CP children, aged between 5 and 12
years, which were distributed into 4 groups: (A) anterior teeth of CP (n= 14), (B) anterior teeth of
NR (n=16),(C) posterior teeth of CP (n=14) and (D) posterior teeth of NR (n=14). These teeth were
hemisectioned, embedded in acrylic resin, grounded and polished. The longitudinal microhardness
analysis was carried out in a microdurometer with a Knoop indenter with a 25-gram load for 5 seconds.
Three rows of 12 indentations were made from the outer surface at 10, 20, 30, 40, 50, 60, 80, 100,
120, 140, 160 and 180 µm. The rows were spaced 100 µm from each other. The values of the three
measurements at each distance were averaged for each tooth and, afterwards, for each group. The
non-parametric statistical test used was the Mann-Whitney U (α=5%). Results: The microhardness
means data were 253.5 ± 55.3 (A), 247.6 ± 45.7 (B), 284.4 ± 68.7 (C) and 252.2 ± 53.8 (D).There was
no significant difference between the groups A and B, as well as groups C and D for each distance and
global average (p>0.05).Conclusion: This study showed that the enamel microhardness of anterior
and posterior primary teeth of cerebral palsy children was similar to the normorreactive children.

Comparison of masticatory function parameters between overweight/obese and normal-weight
children
Objective: The influence of masticatory function on nutritional status of children is important, but
it has been little studied. The objective was to evaluate the association between overweight/obesity
and masticatory performance (MP) and salivary amylase and total protein (TP) concentrations in
81 children, 6-10 years, divided into two groups: overweight/obese (n=35) and normal-weight
(n=46). On clinical examination, the absence of dental caries and the need for orthodontic treatment
were verified. MP was evaluated by the individual’s ability to comminute a chewable test material
for determining the median particle size (X50) and distribution of particles in the different sieves
(“b”). Salivary samples were collected over two days, 4 times/day, for the determination of amylase
and TP area under the curve (AUC). Data were analyzed using descriptive statistics and “t” test/
Mann-Whitney test. A multiple logistic regression model was used to verify the association between
overweight/obesity and the studied variables, controlling for confounders. X50, amylase-ASC and
TP-ASC did not differ between groups. An association between overweight/obesity with highest “b”
was observed, that is, their particles were retained in the larger aperture sieves (OR=2.59, CI=1.036.51, p=0.027). Overweight/obesesubjects were more likely to present chewed particles retained in
the larger aperture sieves, consequently requiring more chewing cycles to break down the test material
in smaller particles.

Wooden foreign body in the orbit of children : report of two cases with different patterns of
tomographic images.
Objective: Wooden foreign bodies in the orbit can lead to a host of complications, from local infections,
facial deformities, to visual problems, for this, the importance of identifying and radiographic location
for correct handling. The aim of this study was to report two cases of foreign bodies in the orbit of wood
two male children, that because of the trauma conditions, showed different patterns of tomographic
image. In the first case, a 11 year old suffered a fall tree and presented an injury infra -orbital on the
right side. When performing CT scan was been a hypodensity in the region. In the second case, the
patient 3 years fell from a wooden bridge over a mangrove area, and injured the medial left orbit. The
computed tomography (CT ) performed hyperdense, which may be due to contamination with other
materials such as sand, mangrove, which were on the wooden splinter that hit the child. Both patients
were treated surgically with removal of foreign body. There were no injuries to bone structures and
both had postoperative infection, treated with antibiotics. The postoperative course was satisfactory
and without visual deficits. A careful clinical examination and also the CT images are essential for
proper planning and execution of surgical treatment.

Green teeth-What is the clinical significance?
Abstract: Green teeth are an uncommon condition. This anomaly usually represents systemic disorders
in pediatric patients. Objective: Presentto the pediatric dentist the systemic disorder that lies behind
the green teeth.Case report: we describe a form of tooth pigmentation caused by serum bilirubin
deposition during dental calcification and present the levels of bilirubin during the three months
after birth when the crown of the deciduous teeth are still forming. Such anomaly does not have
symptoms, but it causes a displeasing aspect and great anxiety within the family. Conclusions: The
case here reported reassure the relevance of the past medical history and of the exams of prolonged
conjugated hyperbilirubinemia to confirm the diagnosis. For this case, no aesthetic treatment had
been undertaken because the child was still too young and not yet conditioned. The treatment plan
included returns every 3 months for maintaining oral health with no caries.

Near infrared-based technology in early occlusal caries detection
Objective: This study aimed to evaluate in vitro the performance of near infrared laser transillumination
(NIR-TI), for detecting early occlusal caries in permanent teeth and compare it with the Quantitative
light-induced fluorescence (QLF) and DIAGNOdent (DDPen). Ninety-four occlusal surfaces
presenting ICDAS scores ranging from 0 to 3 were selected. For the NIR-TI examination, images
were captured using the NIR-TI prototype, which consists of a laser beam (808 nm) and an infrared
CCD camera. One occlusal site on each tooth was assessed twice by two examiners. The teeth were
histologically prepared and assessed for early caries presence. Sensitivity, specificity, accuracy and Az
were calculated and McNemar test was applied to compare the values among the methods. Intra and
inter examiners repeatability was analyzed using Cohen’s Kappa coefficient. The NIR-TI showed
values of sensitivity (0.68), specificity (0.85), accuracy (0.73) and area under ROC curve (0.76),
similar those achieved by the fluorescence methods (p>0.05). A high intra examiner repeatability
was obtained for the three tested devices. For inter examiners repeatability, the highest values were
obtained by DDPen and QLF (0.81 and 0.73 respectively) whereas the NIR-TI system obtained
0.58. The results showed that the performance of the NIR-TI system was similar to DDPen and
QLF, and can be a viable technology to aid in early occlusal caries detection.

Genetic determinants of Molar-Incisor Hypomineralization
Objective: To evaluate the association between variation in enamel formation genes and susceptibility
to Molar-Incisor Hypomineralization (MIH).Method: DNA samples from 71 cases with MIH and
89 unaffected controls were studied. Eleven markers in five genes [ameloblastin (AMBN), amelogenin
(AMELX), enamelin (ENAM), tuftelin (TUFT1), and tuftelin-interacting protein 11 (TFIP11)]
were genotyped by the TaqMan method. Chi-square was used to compare allele and genotype
frequencies between cases and controls. Results: The markers rs3796704 (ENAM), rs4694075
(AMBN); rs5997096/rs134136 (TFIP11), were associated to MIH (p<0.05). Conclusion: This study
demonstrates that genes involved in enamel formation are associated with enamel hypomineralization.

Different bacterial models to induce in vitro formation of non-cavitated caries lesions
Objective: To compare different bacterial models to induce in vitro formation of non-cavitated caries
lesions. Methodology: A total of 240 autoclaved bovine enamel blocks with microhardness 310.5
± 42.8 KHN were used. The blocks were randomly divided into 4 groups (n = 60) in accordance
with the bacterial model: (A) S. mutans, (B) S. mutans and L. acidophilus, (C) S. mutans and L. casei
and (D) S. mutans, L. acidophilus and L. casei. The microorganisms were inoculated in a cariogenic
solution containing the enamel blocks, which was changed every 48 h. For each group, the blocks
were randomly divided into 12 subgroups (n = 5) according to the caries induction period (4 to 44
days). Results: The superficial microhardness analysis showed statistically lower values for groups C
and D than groups A and B (p<0.05). The integrated loss of subsurface hardness (ΔKHN) was lower
for groups A and B compared to groups C and D (p<0.05). Regarding the depth of caries lesion by
means of polarized light microscopy, it was observed that group A showed statistically lower values a​​ nd
groups C and D the highest values. Group B showed higher values than group A (p<0.05), justifying
the bacteria interaction. The period of 8 days for group B was the most appropriate for the induction
of non-cavitated caries lesions. Conclusion: The bacterial model using S. mutans and L. acidophilus was
less aggressive and may be used to induce the formation of non-cavitated caries lesions.

Effect of fluoride products on salivary parameters involved in the process of demineralization and
remineralization (DES-RE)
Objective: To evaluate salivary parameters involved in the process of demineralization and
remineralization after application of fluoride varnish NaF 5% and solution for mounth rinse NaF
0.05%. Methodology: The study included 50 young adult volunteers aged between 20 and 30 years
of which 25 individuals used the solution NaF 0.05% for mouth rinse and 25 individuals received a
fluoride varnish application NaF 5%. The collection of saliva stimulated mechanically with parafilm
were performed in 3 stages: before using the product fluoridated (control), immediately and 1 hour
after application of the respective product. The salivary parameters evaluated were salivary flow
rate, pH, buffer capacity and concentration of calcium and phosphate. The data were submitted to
ANOVA and Tukey post-test (p ≤ 0.05). Results: The fluoride rinse with NaF 0.05% stimulated
salivary flow rate (33%) and the concentration of calcium (23%) up to one hour after application
of the product (p ≤ 0.05). The application of fluoride varnish stimulated salivary buffer capacity in
pH ranges considered critical for the demineralization of hydroxyapatite (23%) (pH 5.9 to 5.0) (p
≤.05). There were no significant differences in other parameters. Conclusion: The use of fluoridated
products as a solution 0.05% NaF indicated for daily mouth rinse and varnish NaF 5% stimulates
salivary parameters involved in the process DES-RE, as salivary flow rate, buffer capacity and calcium
concentration.

Effect of breastfeeding on the biochemical composition of the saliva of babies
Objective: The breastfeeding is essential for nutrition and development of the newborn, having great
value in improving the immature immune system, due to the maturation of IgA, the main antibody
found in breast milk. The aim of the study was to evaluate the effect of breastfeeding on salivary
parameters defense babies. Participated 53 children of both genders, aged 4 and 18 months of life. The
groups were formed by babies who breastfeed chest (n=25) and infants who are fed only infant formula
(n =28). Samples of unstimulated saliva were collected through a gentle suction using a plastic catheter.
The parameters assessed were salivary salivary flow, pH, buffer capacity, amylase activity, total protein
concentration and immunoglobulin A ( IgA ). Statistical comparisons between groups were made by
paired “t Student” (two- tail), with a significance level of 5 %. The results indicated that breastfeeding
increases the rate of secretion of IgA in saliva of infants (p=0,02). There were no statistically significant
differences between the two groups in other salivary parameters studied. Conclusion: Breastfeeding
helps with oral immunity in infants by increasing the secretion of salivary antibodies.

Effect of CO2 laser and fluoride dentifrice on demineralization around orthodontic
brackets - an in situ study.
Objective: Verify whether the irradiationof CO2 laser with an energy density of 20.0J/cm2 combined
with the use of an orthodontic adhesive could reduce enamel demineralization around orthodontic
brackets. Methods: 160 specimens of human enamel were divided into the groups. During two
phases of 14 days each, 20 volunteers used a device intra oral palatal containing four specimens of
human enamel, which were randomly divided into 4 groups: 1- Adhesive +NonFluorideToothpaste
(NFT)(control), 2- CO2Laser + Adhesive + NFT, 3- Adhesive + Fluoride Toothpaste (FT) and 4CO2Laser + Adhesive + FT. Volunteers dripped ont he slabs a 20% sucrose solution eight times a day
at predetermined times. After each phase, the biofilm was collected and the fluoride concentration was
analyzed. The mineral loss around orthodontic brackets was determined by micro hardness analysis.
The results of the fluoride concentration in dried biofilm were analyzed by Lilliefors and KruskalWallis test followed by theStudent Newman-Keuls test (α= 0.05) and the results of the mineral loss
were analyzed by Lilliefors test followed by ANOVA.Results: Higher fluoride concentrations in the
biofilm were found for groups 3 and 4 than for groups 1 and 2. Conclusion: The adhesive system
showed to be effective in reducing demineralization in situ around orthodontic brackets and the
presence or absence of CO2 laser and fluoride tooth paste had no influence on the enamel mineral loss
around orthodontic brackets.

Effect of CO2 laser(ƛ=10,6 µm) and acidulated phosphate fluoride on CaF2 formation and in the
inhibition of lesion progression of demineralized dental enamel – In vitro study.
Objective: We investigated if CO2 laser irradiation with two energy densities combined with
acidulated phosphated fluoride gel (APF-gel) enhances the formation of calcium fluoride and reduces
the mineral loss of demineralized enamel specimens (DES). Methods: 300 DES were used in this
research. 100 DES were divided into 10 groups: control group and in 09 groups CO2 laser with
two energy densities(11,3 J/cm2 ou 20,0 J/cm2) was used before, during or after APF-gel application
and CaF2 was determined in these specimens. Following, 50 specimens submitted to the same
treatments were evaluated for CaF2 formation before and after CaF2 extraction by scanning electron
microscopy microscopy(SEM) analysis. Moreover, 150 specimens were dived into 10 groups, treated
in the same way and submitted to a pH cycling. Lesion depth and enamel mineral loss(ΔS) were
determined. Results were analised by ANOVA followed by Tukey test. Results: CaF2 concentration
varied from 0,15 (laser 20,0 J/cm2) to 5,87 (Laser 11,3 J/cm2+ during APF application). The mean of
ΔS ranged from12.242,9±2.605,0b(control) to 7.398,5±1.593,0a (APF). Lesion depth ranged from
138,35 μmb (control) to 54,40 μma (laser 20,0 J/cm2 + APF). SEM images showed spherical deposits
which morphologically resemble CaF2. Conclusion: The use of CO2 laser irradiation at 11.3 J/cm2
during APF-gel application enhanced CaF2 formation. However, regarding inhibition of enamel
demineralization, no synergistic effect was found with the combined therapy.

Formation of CaF2 on demineralized bovine enamel subjected to APF application associated with
immersion in milk
Abstract: The formation of calcium fluoride(CaF2) after acidulated phosphate fluoride (APF)
application does not deliberately increases with the concentration or time of application. Could the
availability of calcium ions from the milk increase the formation of CaF2? Objective: To evaluate
in vitro quantitative and morphological the formation of CaF2 after APF application associated with
immersion of demineralized bovine enamel in milk. Methods: Blocks of bovine enamel (n =14/
group), selected by surface hardness were subjected to demineralization, and randomized into the
following groups: (I) APF, (II) milk, (III) milk+APF, (IV) APF+milk. The specimens were kept
in human saliva for 2 hours for formation of salivary pellicle. Later treatment was performed, and
after the specimens was kept for 30 minutes in artificial saliva. The content of CaF2 was determined
in 12 specimens. In the 2 remaining was performed morphological analysis by SEM. Results: Group
IV showed statistically higher concentration (p=0.036) than in group I, respectively 41.91±5.25 and
33.29±6.37 mgF/cm2. All groups had ATF were statistically different from the control group II (0.23
± 0.10). Group III showed statistically different from groups I and IV, obtaining an intermediate value
(4.96±37.75). In the SEM images was observed the CaF2 formed. Conclusion: It can be concluded
that the immersion of the enamel in milk after APF application increased the amount of CaF2 formed
under these conditions.

Pyogenic granuloma on the tongue: a case report on pediatric patient
Objective: The objective of this study is to describe the surgical removal of Pyogenic Granuloma on
the tongue, and its recurrence. Patient, 4 years and 5 months old, male, sought to UFSC Dentistry
Clinic reporting difficulty in speech and eating because of injury to the tongue. Clinically there was
a presence of an exophytic lesion, located on the right side of the tongue, with lobulated surface, a
sessile base with well-defined limits. The parents reported that the child had the habit of nibbling and
suck his tongue. The child was submitted to surgical removal of the lesion, and guidance on removing
the habit. After the removal of the lesion, the collected material was sent for pathology analysis, where
it was confirmed the diagnosis of Pyogenic Granuloma. Due to habit persistence, the lesion recurred
after a month and the patient underwent a new surgery with the same histopathological diagnosis.
After 12 months follow-up no recurrence of the lesion was found. It was concluded that success of
the treatment depends on the surgical removal of Pyogenic granuloma associated with psychological
support and cooperation of the patient to remove the habit.

Molar-incisor hypomineralization associated to deciduous molar-hipomineralization: clinic study
in children
Objective: This study investigated the presence and relationship between molar-incisor
hypomineralization (MIH) and deciduous molar hypomineralization (DMH). Material and Methods:
One single trained and calibrated examiner examined 379 children with ages ranging from 6 to 10
years old. Full mouth inspection was conducted following the EAPD 2003 criteria for MIH and
DMH diagnosis, including canines’ tips in the investigation. Statistical analysis was performed by the
use of the Mann-Whitney Rank Sum Test, chi-square test and odds ratio. Results and Discussion:
The prevalence was 24.2% for MIH and 12.4% for DMH. The most commonly permanent teeth
affected by hypomineralized enamel had been, in descending order: 36, 46, 16 and 26; the least
affected had been, also in descending order: 11, 21, 22 and 12. The 4 index deciduous teeth were
statistically equally affected. All permanent first molars were affected in 18.4% of the 92 MIH cases,
three first molars in 11.9%, two first molars in 28.2% and only one first molar in 15.2% of cases. No
teeth had been extracted due to MIH or DMH. Children with DMH had an odds ratio of 4.18 for
MIH in comparison to children without DMH. Conclusion: Children with DMH are four times
more vulnerable to MIH.

Impact of traumatic dental injuries and malocclusions on quality of life of preschool children
Objective: Assess the impact of traumatic dental injuries (LDT) and malocclusions on quality of life
related to oral health (OHRQoL) in preschool children in Diadema, Brazil. Methods: 1215 children 1-4
years of both genders were systematically selected during the National Day of Children’s Vaccination
in Diadema, SP in 2012. Parents or guardians answered the Brazilian version of the questionnaire
ECOHIS (B-ECOHIS) to assess the impact of OHRQoL. Clinical assessments were performed by
19 dentists trained and calibrated by adopting the criteria Glendor (2008) for the diagnosis of LDT
and to malocclusion was considered the presence of anterior open bite, anterior crossbite, increased
overjet (> 3mm) and posterior crossbite. Poisson regression models adjusted for dental caries (CI 95%)
were used to assess the association between LDT, malocclusion, socioeconomic factors considering
each domains and the total score of the B-ECOHIS. Results: The multivariate adjusted model of
Poisson regression showed an association between some domains of the B-ECOHIS and clinical
conditions (p <.05). No association was observed with the presence of LDT and malocclusion in the
total score. Only the severity of the LDT (Complicated LDT) showed a negative impact on OHRQoL
(RR = 2.10; p = 0.048). Conclusion: The presence of LDT and Malocclusion no showed impact on
OHRQoL, but the complicated LDT has a negative impact on OHRQoL in this population.

Impact on the quality of life and esthetic recovery after dental traumatic injury
Objective: The aim of this study was to relate the clinical management in two cases of pediatric patients
who suffered dental traumatic injuries and the influence of the dental procedureon the quality of life
related to oral health of the patients and their families. After the trauma, the patients were referred
to the Dental Traumatology SurveillanceCenter- UFRJ with esthetic complaint and difficulty in
socializing due to coronal fracture in the upper central incisors. In the first case, a 12-year-old boy was
already 6 month without treatment and it was performed pulpectomy and bonding of the fragment.
In the second case, a 8-year-old searched treatment 2 days later the trauma and it was performed
pulpotomy with MTA and bonding of the fragment. The assessment on the quality of life was done
trough questionnaires (CPQ, P-CPQ and FIS) before and one week later the treatment. The indexes
varied in the first case from 32 to 9 in the CPQ (11-14), 42 to 12 in the P-CPQ and 24 to 4 in the
FIS, before and after the treatment, respectively. In the second case, from 38 to 20 in the CPQ(0810), 94 to 28 in the P-CPQ and 39 to 10 in the FIS. We concluded that the esthetic recovery through
fragment bonding is a rapid and practical solution, especially in children. Beyond that, dental trauma
causes impact in the quality of life of the child and the family and the reduction of this impact is
already observed one week after the treatment improving welfare of the children.

Implant and prosthesis in child with ectodermal dysplasia
Objective: The objective of this study is to report a case of oral rehabilitation in a child with Ectodermal
Dysplasia. Patient VPS, female, 8 years, sought treatment at the Clinic of Pediatric Dentistry, UFSC,
with the chief complaint of “multiple dental absences”. On physical examination, there were observe
changes in the development of hair, eyebrows and eyelashes, dry skin, lips were prominent, and the
child had a senile appearance. The clinical and radiographic examination showed congenital absence of
several primary and permanent teeth. The teeth in the oral cavity had microdontia with high mobility,
incomplete root development, and wide pulp chamber. The upper labial frenulum was hypertrophic
and showed up with low insertion. The child was with phonetic changes and difficulty of chewing. The
oral rehabilitation was accomplished through the installation of an upper dentures and a mandibular
implant-supported denture. It can be concluded that the installation of dental implants and dentures
in children with Ectodermal dysplasia is a viable alternative for rehabilitative treatment because it is
able to improve the masticatory and phonetic functions, rescues self - esteem and enables a better
social contacts for the patient. It is worth mentioning the importance of performance monitoring
and multidisciplinary professional in order to preserve and restore maximum functional balance and
aesthetic before oral conditions imposed by the syndrome.

Incorporation of gluconate or chlorhexidinediacetate to a Glass Ionomer Cement: porosity and
surface roughness.
Abstract: Among the antibacterial chlorhexidine (CHX) is considered one of the most effective
substances and safe. The objective was to evaluate the porosity and surface roughness of a GIC after
addition of gluconate or diacetate CHX. Were prepared 10 specimens (n = 10) and randomly assigned
into two groups: control C: CIV; G1: GIC and CHX gluconate 0.5%, G2: GIC and CHX gluconate
1.0%, G3: GIC and CHX gluconate 2.0 % D1: GIC and 0.5% CHX diacetate, D2: GIC and 1.0%
CHX diacetate and D3: GIC and 2.0% CHX diacetate. The surface roughness was obtained by
the arithmetic mean of three readings taken on each specimen and the surface porosity by analysis
of photomicrographs in the Image J program Analyses of variance of two factors and Tukey’s test,
with significance level of 5%. We observed a significant effect only the square CHX diacetate at
all concentrations (p <0.001) on the percentage of area occupied by the pores, increasing it. For the
number of pores, a significant decrease was observed in the same CHX diacetate and 1% CHX
gluconate 0.5%. There was no significant effect on any of the concentrations for the surface roughness
(p> 0,05). It can be concluded that to associate the CHX to the GIC, the best option is to CHX
gluconate 1% or 2% because no effect on surface roughness and presented number of pores and the
area occupied by them similar GIC in its original form.

Influence of attentional and executive functions in the development of caries in individuals with
cerebral palsy
Objective: The aim of the present study was to evaluate the existence of an association between
attention/executive functions and the development of dental caries in individuals with cerebral
palsy (CP). Seventy-six children with CP were selected from a physical rehabilitation center and a
school serving children with disabilities. The control group was made up of 89 children without
neurological impairment. Socioeconomic status, presence of teeth with cavities due to caries, degree
of motor impairment and intellectual, executive and attentional functions were assessed. Mean
age of participants was 8.9 years (SD=3.56). The CP group had a significantly lower performance
(p<0.05, Mann-Whitney test) on the intelligence, attentional function and executive function tests
in comparison to the control group. Controlling for the clinical diagnosis (CP or control group),
motor impairment and intellectual function, the significant explanatory variables for the presence
of teeth with cavities were performance on the Complex Rey figure test (OR=0.941) and the Digit
Span subtest of the Wechsler Intelligence Scale for Children in backward order (OR=0.581). After
controlling for intellectual function, clinical diagnosis and motor impairment, deficits in executive
and attentional functions increased the odds of developing dental caries in children with cerebral palsy.

Influence of polishing systems and staining solution on the color stability of the composite resins
Objective: To evaluate the influence of different polishing systems and staining solution on composites
color stability. Cylindrical samples (7mm diameter x 2mm thick) were prepared with Filtek Z350XT
and Vitalescense composite resins. After 24h at 37°C, the samples were polished with Soflex or Jiffy
polishing systems. They were divided into 8 groups (n=9) in accordance with composite, polishing
system and staining solution (coffee/CF and artificial saliva/SA control). Initial color measurements
were made using CIEL*a*b* system. Then, each sample was immersed in 4 mL of solution for 15
min, 3x/day for 14 days. After that, color was measured again and variations of color were calculated
(ΔE). The normal distribution of data was verified and submitted to three way ANOVA (p<0.05).
Both composites exhibited some staining after degradation in CF and SA. Statistically significant
differences were observed in triple interaction (p=0.001). Irrespective of the polishing systems, the
both composites showed higher staining in CF than SA. Z350, in both solutions, exhibited similar
staining for SofLex and Jiffy. However, Vitlescence in SA showed higher staining with Jiffy; and in
CF, exhibited higher staining with SofLex. The staining was influenced by the solution, composite
and polishing system. The Vitlescence showed less staining with SA and SofLex.

Influence of socioeconomic and clinical factors in the occurrence of dental trauma in preschool
children
Objective: To evaluate the prevalence of trauma in primary dentition and to investigate its association
with sociodemographic and clinical factors. Methods: A population-based cross-sectional study was
conducted with a random sample of 301 children aged between one and five years seen at Children’s
Vaccine Campaign. Data were collected through examination of primary incisors, evaluation of lip
coverage and size of incisal overjet. Parents were interviewed about socioeconomic factors (maternal
education, monthly family income, number of children) and identification of the child. Data
were analyzed using the chi-square test and Poisson regression with robust variance. Results: The
prevalence of dental trauma was 33.9%. The dental trauma was more frequent among children with
overjet> 3 mm (p <0.001), inadequate lip coverage (p <0.001) and higher family income (p = 0.024).
In the Poisson regression model adjusted for sex, maternal education and number of children, it was
observed that children with severe overjet (PR: 1.53, 95% CI, 1: 05 to 2: 22), inadequate lip coverage
(PR: 2.00, 95% CI, 1.41-2.84) and whose family had monthly income ≥ 2 minimum wages (PR:
1.52, 95% CI, 1: 10 to 2: 12) had a higher prevalence of TDI. Conclusions: The prevalence of dental
trauma was high and increased with household income, size of incisal overjet and inadequate lip
coverage.

Traumatic intrusion of permanent tooth with 02 years follow-up: Relate of Case
Abstract: Intrusive luxation is represented by a axial displacement of the tooth toward the alveolar
bone and is considered one of the most severe types of dental trauma and a rare injury. This paper
aimed to report a 02 years follow-up of one patient, 8-year-old with class II malocclusion, that
suffered traumatic intrusion type I of her central incisor. The patient was assisted at emergency room
Mário Pinotti, Belém, few hours after trauma in 2011. The patient had fallen and hit her permanent
upper central incisor on the ground. Her face and upper lip were injured. Upon clinical examination,
swelling could be detected and intrusion of tooth 11, and a small incisal fracture of tooth 12 could
also be observed. No alterations were observed in the radiographic exam, but immature radicular
development was detected. The treatment chosen was to watch and wait for spontaneous re-eruption.
After 1 year and 4 months, complete eruption of the tooth was detected. Radiographic examination
showed typical radicular formation and almost completely pulp canal and crown obliteration, without
apical lesion. In tooth with immature root development, no active treatment appears to result in fewer
complications and conserve vital pulp.

Regional odontodysplasia: case report
Abstract: This case report describes a longitudinal evaluation and rehabilitation of a pediatric patient
with regional odontodysplasia. Female patient presenting caries lesions, looked forpediatric dentistry
department of college with complaining of changes in primary dentition development. Medical
history and clinical examination showed that patient had lost vertical dimension and, in addition, a
history of poorly treated lingual hemangioma. Radiographic examination detected presence of some
primary and permanent dysplastic teeth which confirmed diagnosis of odontodysplasia regional. Were
made restorations of decayed primary teeth and follow-up. Over time, we opted for the extraction of
decayed and dysplastic primary teeth and ulectomy in first permanent molars region as they showed
delayed eruption. During monitoring period, oral rehabilitation partially reinstated occlusion and
vertical dimension of the patient. It can be concluded that the causes of regional odontodysplasia
remain unknown and no known etiologic factor may be associated with the occurrence in this
case, a multidisciplinary involvement is necessary for evaluation and resolution of consequences of
odontodysplasia.

Professional prophylaxis optimization in infants by using previous dental plaque disclosure
Objective: Given the difficulty of controlling dental plaque at home in infants, the professional
prophylaxis becomes an important method. Prophylaxis is usually performed with direct visualization
of the dental plaque, however looking toward the baby’s negative behavior in attendance, the
procedure is liable to failure. It was evaluated the effectiveness of dental plaquedisclosure to optimize
prophylaxis in infants. Methodology: The sample was composed of smooth surfaces (SS) and occlusal
surfaces (OS) of teeth of 25 infants. The randomized crossover clinical study, had GI-with disclosure
prior to prophylaxis,and GII-withoutdisclosure (washout/1month). The plaque disclosure agent
was 1% malachite greenand the dental plaque was assessed by Greene; Vermillion Index for SS and
Mestrinho et al. for OS. The prophylaxis was performed by a single professional that was different
from the evaluator(Kappa-87%). Results: Dental plaque removal was more efficient and faster for GI
(Wilcoxon/p<0.05) and there was an inverse correlation between plaque index and the duration of
prophylaxis (Spearman/p<0.05).The child behavior did not result in difference of plaque index (MannWhitney/p>0.05). There was a positive correlation between difficulty in performing the prophylaxis
and plaque index in OS for both groups (Spearman/p<0.05). Conclusions: Dental plaquedisclosure
prior to prophylaxis is an effective method, which reduceswork time and improves the quality of the
procedure.

Parents as predictors of the impact of oral health on quality of life in children suffering from sickle
cell anemia
Objective: To analyze the correlation between the impact of oral conditions on quality of life in
children suffering from sickle cell anemia through the children’s and parents’ statement and the
impact on their families reported by their parents. Methodology: It is a cross sectional study including
a hospital sample. The instruments used were: CPQ8-10, P-CPQ and FIS. We analyzed the results
using the Mann Whitney test and Spearman correlation coefficient. Results: We interviewed 56
children and their parents. The Mann-Whitney test indicated that children felt more impact on the
actual conditions of the mouth which were perceived by their parents (p = 0.0169), with significant
differences in subscale regarding oral symptoms (p = 0.0003). There was evidence of a low median
correlation between the results obtained in the group of parents and children in sub-scales: oral
symptoms and functional limitations (rs = 0.362 and rs = 0.342, respectively). However there was
a high correlation between the parents’ report about this impact on quality of life concerning their
children’s life and their family (rs = 0.641). Conclusions: The children showed greater feeling of oral
health impacts on their quality of life than their parents reported. There is a high degree of coherence
of parental perception related to the impact of oral health of their children in the same quality of life
and the impact that this condition represents on the family of those children.

Parents feel guilty for oral health problems in preschool children?
Objective: The aim of this study was to assess the presence of parental guilt and its association with
early childhood caries (ECC), traumatic dental injuries (TDI), anterior malocclusion traits (AMT)
and oral mucosal lesions in preschool children. Metodology: A transversal study was carried out with
a randomic representative sample of 382 children with age between 2 and 5 years old of Serro, MG,
Brazil.Data collection involved oral examinations of children, carried out by calibrated examiners,
and their parents answered a socioeconomic questionnaire and the Early Childhood Oral Health
Impact Scale (ECOHIS). The question of ECOHIS related with guilt was used as the dependent
variable. Data analysis involved descriptive statistics and Poisson regression (α=5%).Results: A total
of 12.3% of parents felt guilty because of the child’s oral condition.Parents of children with 3 years of
age [PR: 3.33; CI=1.01-10.96; p=0.048], of male gender [PR: 1.83; CI=1.08-3.11; p=0.024], whose
children had low severity [PR: 3.58; CI=1.69-7.55; p=0.001] or high severity of ECC [PR: 4.60;
CI=2.14-9.90; p <0.001] had a higher prevalence of guilt. No association was found between parent´s
guilt and TDI, AMT, oral mucosal lesions and socioeconomic factors. Conclusion: The parent´s guilt
was associated with children with 3 years old, male gender and with low or high severity of ECC.

Treatment Profile at Urgent Dental Care Service for Children and Teenagers from Faculdade de
Odontologia de Araraquara (FOAr) – UNESP
Objective: The Urgency Dental Treatment for Children and Teenagersat FOAr offers dental
treatment for patients with acute pain. The objective of this study was to evaluate the treatment profile
of patients between 0-13 years treated at the Urgent Dental Care service offered by FOAr. All reports
of emergency treatment provided by an integrated system were evaluated. The data analyzed were:
numbers of patients, treatments and type of procedure performed. These data were tabulated and
submitted to descriptive analysis. From 1997 to 2012, a total of 13,849 patients were treated; 25,786
visits and 86,279 procedures were conducted. It was observed that the most common procedure
done was those related to the disease´s diagnosis, followed by preventive procedures. The operative
procedure performed most frequently was restorative, followed by endodontic treatment. The large
number of preventive procedures performed together with operative procedures collaborated to
caries risk reversal and to the maintenanceof patient’s oral health. The fast referral of patients for
elective treatment, together with the preventive procedures performed also contributed to a decrease
in demand for urgent dental care over the years.

Living Without Caries Program
Objective: The aim of this study was to present the results of 12 years of the project Dentistry for
Babies from ICT / SJC - UNESP, Living Without Caries Program. The dental education of the
mother occurs before the baby’s first appointment. The treatment protocol is characterized by three
stages: educational lecture for pregnant between the 6th and the 8th gestational month, the first dental
appointment of the baby between the 4th and 6th month of life; dental appointment (return every 4
months) until the child reaches 48 months of age. The service is conducted by dentists and coordinated
by professors of the program. The results (period between 2001 to 2012) showed that of 235 children
who joined the program, 120 were followed until they are 12 months, 42 to 24 months, 18 to 36
months and 56 to 48 months. 57 children followed up to 36 months and 48 months completed the
development of the primary dentition without caries establishment and 17 developed carious lesions.
The failure factors were the lack or neglect hygiene habits at home; uncontrolled eating habits and
not attendance to the program. We conclude that the consolidation program was obtained due to the
non-development of caries in children who used rational sugars, instituted early oral hygiene habits
and were assiduous to the dental appointments.

What is the preventive effect of dentifrices on non-cavitated caries lesions?A systematic review
Background: Although dental caries have been declining, initials caries lesions may be underestimated
and it is not known whether the use of dentifrices in different concentrations is effective in preventing
the progression of these lesions. Aim: To determine the efficacy of fluoride dentifrices with different
concentrations in the prevention of initial caries lesions in children and adolescents. Methods: Two
independent reviewers searched PubMed until 06/2013 to identify papers published in English. The
eligibility criteria were: (1) to be a randomised controlled trial or a cluster-randomised trial; (2) to
compare standard fluoride toothpaste with placebo or fluoride toothpaste of a lower concentration
with regard of caries prevention (3) in subjects until 16 years old (4) a follow up of at least 1 year (5)
data about non-cavitated or initial caries lesions. Descriptive and qualitative analysis of the included
studies were performed and also the evaluation of individual risk of bias. Results: Only one study was
included from the 268 articles initially searched. This study showed results of initial or non-cavitated
caries lesions threshold and compared low F and standard F dentifrices. However, it did not show
allocation concealment and random sequence generation. Conclusion: There is still no evidence that
toothpastes with different fluoride concentrations have the same efficacy in preventing progression of
non-cavitated lesions.

Dental rehabilitation with occlusal replica technique in Pediatric Dentistry
Objective: The objective of this clinical case was to demonstrate the occlusal replica technique with
acrylic resin in a first permanent molar, aiming to preserve the occlusal aesthetic and the original
anatomic characteristics of the dental element. Clinical Case Description: Patient, female, 8 years old,
presented clinically caries lesion on tooth 46, pigmentation and microcavitation, with the occlusal
anatomic characteristics preserved. Radiographically, the caries lesion was extended into deep dentin.
After regional anesthesia, under absolute isolation, the matrix was made using a translucid acrylic resin.
The cavity preparation was performed with a dental round diamond drillon a high-speed rotating
instrument, and then the carious tissue was removed with dental round drillon low-speed rotating
instrument and dental excavators. Glass ionomer cement provided pulp complex protection, and
then the adhesive technique was performed with incremental resin restoration. After being internally
covered with glycerin, the matrix was repositioned on the last layer of the composite resin and then it
was light-cured. After the procedure, the need of occlusal adjustment was checked. Conclusion: The
occlusal replica technique optimized the clinical time, simplifying the sculpture, occlusal adjustment,
finishing and polishing procedures and allowing a better aesthetic restoration.

A esthetic and functional rehabilitation of a child 5 years with early childhood caries: a case report
Abstract: Despite the decline in caries, economically disadvantaged families have difficult access to
guidance on oral health, as well as preventive and restorative dental treatments. The objective of this
study was to describe the clinical case of oral rehabilitation of a patient with early childhood caries.
On clinical examination, there was extensive caries lesions with no clinical crown of upper deciduous
teeth and caries in teeth 73, 74, 75, 83, 84 and 85. After clinical and radiographic examination was
indicated for extraction of upper teeth and pulpectomy teeth 75, 84 and 85. The treatment plan was
prepared following the criterion of urgency: adequacy of the oral cavity, removal of foci of infection
with dental extractions, endodontic and restorative treatments. Were made of fluoride varnish
applications in direct restorations and lower teeth with composite resin teeth 73, 75, 83 and 85. After
completion of the pulpectomy, the teeth 74 and 84 receiving steel crowns. Orientation educationalpreventive oral care was given to the child and the person responsible for the treatment. Following
the procedures described above was made dentures. The patient received speech therapy speech to
readjust to the new oral condition. It can be concluded that the treatment was successful, as with oral
rehabilitation was the restoration of masticatory function and aesthetics, promoting better quality of
life for the patient.

Replantation of avulsed primary teeth: a systematic review
Background: There is little evidence regarding the risks and benefits of replantation of avulsed primary
teeth. Aim: To perform a systematic review of the literature about the replantation of avulsed primary
teeth, analysing the risks and benefits to help guide dentists regarding the best clinical decision making
in such cases. Methods: Medline/Pubmed, LILACS and SciELO databases were surveyed for articles
on the replantation of avulsed primary teeth published in English, Portuguese or Spanish in dental
journals dating from the inceptions of the databases until May, 2013. Results: Of the 882 studies
identified in the search, seventeen fulfilled the inclusion criteria. All 17 studies were case reports
involving a total of 31 replanted primary teeth. In 11 cases there were no negative consequences in
either the primary teeth and the permanent successors. Among the other 20 cases, there were negative
consequences to: only the replanted primary teeth in 10 cases, only the permanent successor in 3
cases; both replanted primary teeth and the permanent successors in 7 cases. Conclusion: There is
a lack of high-quality studies that can help guide clinicians regarding the best approach in cases of
primary tooth avulsion. However, if performed only in optimal conditions, reimplantation may be a
feasible and effective treatment.

Relationship among insoluble polysaccharide, sugar exposure, cariogenic microorganisms and
early childhood caries - A longitudinal study
Objective: We aimed to assess the relationship between early childhood caries(ECC) and extracellular
insoluble polysaccharides (IP) in dental plaque, sugar exposure and cariogenic microorganisms. We
also performed a screening of the ability of S. mutans strains to synthesize glucan in vitro. Methods:
Clinically visible plaque on maxillary incisors was recorded, followed by caries diagnosis in sixty-five
3-4 year-old children at baseline and after one year. Plaque was collected for mutans streptococci
(MS), total microorganism (TM) and lactobacilli (LB) enumerations in selective media, as well as
for IP analysis which was later assessed by colorimetry. In vitro glucan synthesis was assessed by a
zymographic assay and sugar/sucrose exposure by a diet chart respectively. Results: Positive correlations
were found among caries prevalence and MS, TM, LB, solid sucrose and dental plaque. Children with
IP concentrations in dental plaque higher than 2.36 μg/mg, with visible plaque on maxillary incisors,
harboring LB and exposed to solid sugar more than twice/day showed higher risk of developing caries.
(p<0.05). We found no correlation between IP concentrations in dental plaque and the ability of S.
mutans strains to synthesize glucan. Conclusion: Extracellular IP, solid sugar/sucrose, visible dental
plaque and cariogenic microorganisms predicted ECC. The ability of S. mutans strains to synthesize
glucan in vitro did not reflect the IP level in dental plaque of children with ECC.

Oral Health of Children with Cystic Fibrosis Patient
Abstract: Cystic fibrosis is an autosomal recessive disease that brings complications for the respiratory
and digestive systems, and can compromise the quality of life of patients and their families. This
study aimed to investigate the impact of dental caries and periodontal changes on the quality of life of
parents responsible for CF patients, 5-12 years of age ( mean = 8.8) and both genres (33.3 % boys),
in the Ambulatory Child ISCMSP, São Paulo - SP. A cross sectional study was planned analytical
methodology followed the WHO (1997): indicesdmft and DMFT (tooth decay); IPCNT index
(periodontal changes) and WHOQOL (quality of life). Data were analyzed by SPSS version 14.0
using the Spearman test and Mann - Whitney (CI = 95 %, p =.05). Observed mean dmft= 1.3 and
mean DMFT = 0.37; IPCNT = 2, with the presence of dental calculus yellowish predominant in the
inferior incisors, and WHOQOL average = 13.45. There was no statistically significant difference in
the distribution of dental caries and periodontal changes on the quality of life of those responsible (p
> 0.5). Conclusion: Despite not having been observed the impact of oral health on the quality of life
of those responsible for CF patients, it is noteworthy that the average quality of life was found below
the parameters recommended by the WHOQOL group, indicating the need for greater attention to
this particular group.

Oral health in the School of application of UFPA: Smiling School Project
Dental caries is a infectocontagious disease dependent on several factors for its origin and development
which may even lead to teeth loss. Caries´s magnitude and severity in deciduous teeth remains a
public health problem, requiring special attention and global view. Prevention and promotion have
been the target of numerous discussions on population awareness and education importance as
a fundamental instrument in health maintenance. Thus, our aim is to present the“Projeto Escola
Sorridente “(Smiling School Project) and their activities and goals, as well as, the epidemiological
profile of children assisted in th eproject. Through ludical educational and preventive activities focused
on oral health, with collective actions, the Project proposal is to introduce oral health information and
practices to children at 3-5 years, of the early childhood education School of application oft he Federal
University of Pará so then can develop correct habits and grow more healthly and citizens hipsense.
Activities focused on strategies for prevention and oral health promotion in early childhood education,
conducted by the “Projeto Escola Sorridente” has a good chance of forming citizens increasingly
aware, which will be important for them a intenance of a healthier life.

Photodynamic antimicrobial therapy mediated by curcumin on Streptococcus mutans mature
biofilms
Objective: To evaluate the photodynamic antimicrobial chemotherapy (PACT) mediated by
curcumin and a blue LED on S. mutans mature biofilm comparing with a solution of chlorhexidine at
0.12% (CHX) and the effect of a novel single source of a non-coherent light that delivers high power
intensity at a short exposure time over suspensions of S. mutans. Methodology: S. mutans biofilms
were formed on saliva-coated hydroxyapatite discs in batch culture containing sucrose and changed
daily for 5 days. The biofilms were submitted to PACT (2.5 mM of curcumin and 48J.cm2 of blue
LED – 3 min 33 sec) and CHX (1 min). Biofilms were assessed by environmental scanning electron
microscopy, confocal laser scanning microscopy and microbial viability (CFU/mg of biofilm dry
weight). Planktonic suspensions of S. mutans were standardized and submitted to PACT treatment at
low concentrations of curcumin (0.75 uM) exposed to a high power intensity of a white light for an
extra short exposure time (12.2 sec). Results: Significant differences were found to PACT groups in
comparison to controls and CHX to both studies (< 0.05). The morphology of biofilms demonstrated
a high rate of dead cells to PACT group, even though without expressive results regarding biofilm
topography. Conclusions: PACT mediated by curcumin presented antimicrobial effect against S.
mutans biofilms and superior performance when comparison to chlorhexidine. The new source of
light presented a lethal photoinactivation at an extra short exposure time.

Anterior cross-bite treatment in the primary dentition and impact on the quality of life of the child
and family
Abstract: The malocclusions may show up during the first teeth eruption. The anterior cross-bite
directly affects the facial aesthetics and chewing. The anterior cross-bite in the primary dentition does
not necessarily means a class III malocclusion. This alteration may be due to functional deviations
occurred during the deciduous incisors eruption, if this is not corrected in this phase, it may have
a negative impact on the stages of the dentition development: a functional deviation may become a
bone deviation. This case presents a 5 years and 8-months old girl that went to the Pediatric Dentistry
clinic of the FOB/USP with her mother complaining that the anterior cross-bite compromised the
child’s socialization and chewing. The case was solved through the maxilla expansion using the Haas
expansion device followed by facial mask to the anterior bite correction. The result was satisfactory,
anterior cross-bite stabilization was reached allowing the permanent incisors to erupt non-crossed. The
mother related positive changes on the child’s behavior and feeding after de malocclusion correction.
The child became more sociable and better integrated to the family’s and school’s activities and started
to eat better.

Preventive orthodontic treatmentin child
Abstract: Anterior crossbite in the primary dentition does not necessarily mean that the child has a
Class III malocclusion. This change may be due to functional deviations occurred during the early
phase of the primary incisors eruption. If not corrected at this stage, it may have a negative impact on
the later stages of the dentition development: going from functional deviation to skeletal deviation.
Case Report : Two babies, an 1 year and 8 months old girl and a 2 years and 3 months old boy, went
to the Baby Clinic at the FOB / USP. The main complaint of both parents was about their children’s
aesthetics. Additionally the boy’s parents were bothered by the fact that he did not pronounce some
words correctly. Machado & Amaral, based on the Planas principles, developed a treatment protocol
for these cases through occlusal adjustments. By using matrix celluloid crowns for primary teeth,
reanatomizations were made on the crowns of deciduous incisors, this intervention corrected he
anterior cross-bite. The result was quite satisfactory. Besides the aesthetic aspect, it was possible to
restore function and reduce chances of future orthodontic interventions. Parents were also pleased
with the results. The importance of clinical and radiographic follow-up in the later stages of dental
development is highlighted.

The use of toothpaste and tooth brushing practices by preschoolers
Abstract: Several children’s toothpaste formulations are available in Brazil. There is evidence that only
those containing at least 1,000 ppm fluoride (F) have anti-caries effect. Objectives: to estimate the
prevalence of toothpaste use, according to F concentration, in preschoolers attending a health care
center in Rio de Janeiro, and to assess aspects related to the amount of toothpaste and toothbrushing
supervision. Methods: among the 226 adults who were approached in the Pediatric clinic, 190
were interviewed by three dental students using a pre-tested questionnaire. Results: the mean age
of the interviewees was 30.2 years (SD 8.5); the majority of them was the child’s mother (87.9%)
and belonged to the medium economic level – “classe C” (83.7%). The children’s mean age was
3.9 years (SD 1.5). Tooth cleaning was performed by 178 (93.7%) children; 18 (9.5%) did not use
toothpaste, 123 (64.7%) used a pea-size amount of toothpaste or less and 49 (25.8%) used an amount
of toothpaste equivalent to the full head of the toothbrush. Most children (57.9%) brushed their
teeth under parental supervision. The prevalence of the use of non F toothpaste and low F toothpaste
was 11.6% and 2.6%, respectively. Conclusions: although the majority of the children clean their
teeth using toothbrush and a small amount of standard F toothpaste under parental supervision, some
tooth brushing practices that can negatively affect caries control and increase fluorosis risk have been
identified.
