Abstract

: The focus of this study was to test the hypothesis that the amount of buccal corridor associated with dolicofacial, mesofacial and brachyfacial facial patterns has no influence on smile evaluations by laypersons of different age groups. A photograph was constructed of a woman displaying a broad smile. Buccal corridors were modified digitally in increments of 5% and 10%, displaying from 0% to 30% buccal corridor compared with the inner commissural width. Using a visual analog scale(VAS), 150 laypersons divided into 3 groups(n=50) of age-ranges from 15-19, 35-44 and 65-74 years of age rated the attractiveness of five smiles with altered buccal corridors. Differences in the median esthetic scores were analyzed using the Kruskal-Wallis test (P<0.05). Laypersons over the age of 65 years made a less critical judgment as regards attractiveness of the smile. In the comparison between groups of individuals of different age-ranges for the size of the buccal corridor at 0%, 10% and 15% there was no significant difference for any of the facial types(P>0.05). There was significant difference between the groups from 15-19 and 65-74 years of age in evaluating the attractiveness of the smile with the size of the buccal corridor at 20% and 30% for the short(P=0.045, and P=0.035) and long (P=0.029, and P=0.038) facial types, respectively. The hypothesis was rejected. Laypersons over the age of 65 years attributed higher scores. Irrespective of age, laypersons preferred broader smiles with a smaller buccal corridor, with 15% being the limit between the most and least attractive smile.
