Abstract
Aim: This study aimed to investigate the existence of the golden proportion, recurring esthetic
dental (RED) proportion and golden percentage between the frontal view widths of the maxillary
anterior natural dentition among students of Indian origin by the aid of digital photography.
Materials and Methods: This study was conducted with 80 dental students (41 female and
39 male), with ages ranging from 20 to 23 years. Students whose natural smile did not develop
any visual tension with regard to the study’s and their own criteria were selected as having an
esthetic smile. Photographs were taken, and the mesiodistal widths of six maxillary anterior
teeth were measured digitally using software. Once the measurements were recorded three
different theories of proportion were applied and statistical analysis was done.
Results: The golden proportion, i.e., 62% RED proportion and golden percentage were not
observed in the subjects. According to the subjects evaluated, the average width of the maxillary
lateral incisor was 72% of the frontal view width of the central incisor. The average width of
the canine was 84% of the frontal view width of the lateral incisor.
Conclusion: The golden proportion and RED proportion were not observed in the natural smiles
of subjects who were deemed to have an esthetic smile. The values proposed for the golden
percentage theory were not observed in subjects with an esthetic smile. Average frontal view
percentage widths of the maxillary anterior dentition exist and can be useful in predicting
naturally occurring widths in smiles deemed to be esthetic in a specific population.
