Poubel, Denise. The comparative study of facial type determination by
facial and cephalometric analysis in subjects with normal occlusion.
Summary
The purpose of this research was to evaluate the agreement of facial
type determination (brachy, meso and dolicho) among three cephalometric
analyses: RICKETTS (VERT Index), SIRIWAT; JARABAK and JANSON;
WOODSIDE; METAXAS, and two profile
facial analyses:
LEGAN;
BURSTONE and Subjective Analysis. The sample was compounded by 60
subjects, being 24 males and 36 females. All of them were Brazilians,
leukoderms with natural normal occlusion, presenting four out of the six keys
to ANDREWS’s occlusion. As an exclusion criterion, a functional and
dynamic evaluation of the occlusion was also performed. The natural head
position (N.H.P.) and the true vertical (T.V.) were used at the moment of the
lateral cephalograms and the profile photographs taken. These made up the
methodology for the study, an indispensable requirement for the comparison
effect. After statistical analyses (Kappa), the results revealed that, among
the cephalometric analyses, there was a weak agreement between the
RICKETTS (VERT Index) and SIRIWAT; JARABAK analyses. Among the
profile analyses there was no agreement; and when we compare d the
cephalometric analys es and the profile analyses, we verified that there was
a weak agreement between the JANSON; WOODSIDE; METAXAS and
LEGAN; BURSTONE analysis, and between RICKETTS (VERT Index) and
the Profile Subjective Analyses.
