Evaluation of the determinants of facial profile aesthetics

Abstract

Objective: To evaluate the influence of age, gender, sagittal occlusal relationship, facial pattern and 8 facial profile measures on profile aesthetics. Methods: Contingency tables, chi-square test and Cramer's coefficient were used to evaluate the possible association between the scores assigned by 32 examiners (14 orthodontists, 12 laypeople and 6 artists) to the aesthetics of the profile of 100 Brazilian Caucasian adults, all patients with lip seal competence, and age, gender, sagittal occlusal relationship, facial pattern and the variables of the numerical analysis of the facial profile. Results: No association was found between age, gender and sagittal occlusal relationship and the aesthetics of facial profile. An association was observed between profile scores and facial pattern, facial convexity angle and lower face angle. Conclusions: Among the factors evaluated in this study, facial profile convexity and anterior chin projection were the key determinants of facial profile aesthetics.
