PEIXOTO, Letícia Monteiro; LOURO, Renata Loureiro; GOMES, Antônio Augusto  and  NASCIMENTO, Ana Paula Camatta do. Photographic analysis of esthetic dental proportions. RGO, Rev. gaúch. odontol. (Online) [online]. 2012, vol.60, n.1, pp. 13-17. ISSN 1981-8637.

Objective The aim of this study was to analyze smiles considered to be harmonious, by observing the patterns of proportion between the width and length of the central incisor and its shape. Methods A total of 85 people with harmonious smiles were used for the sample, divided by sex and age. Two photographs were produced for each patient: smile and occlusion, using a lip retractor. The photographs were scanned and transferred to the software application Corel Draw 10, where the esthetic dental factors were measured. Results It was shown that harmonious smiles usually have a height/width ratio of between 65% and 85% and a predominance of the triangular shape, followed by the square shape. Conclusion Despite differences in tooth size and shape, they have, both individually and in conjunction, a certain proportion, as does the face and more specifically, the mouth.
