Objective: To compare the aesthetic perception of different anterior visible occlusions in different facial and dental views (frontal view, lower facial third view and dental view) by lay persons.

Design: Cross-sectional survey, Lima, Perú, 2002.

Subjects: The different views were rated by 91 randomly selected adult lay persons.

Main outcome measurement: Visual Analogue Scale (VAS) ratings of aesthetic perception of the views.

Results: Anterior visible occlusion, photographed subject and view (p<0.001) had a significant effect on the aesthetic ratings. Also gender (p=0.001) and the interaction between gender and level of education (p=0.046) had a significant effect over the aesthetic rating.

Conclusions: A lay panel perceived that the aesthetic impact of the visible anterior occlusion was greater in a dental view compared with a full facial view. The anterior visible occlusion, photographed subject, view type are factors, which influence the aesthetic perception of smiles. In addition, gender and level of education had an influence.

Key words: Facial aesthetics, dental aesthetics, smiling, photography, lay persons
