Abstract

Objective: To assess and compare the perception of Buccal Corridor (BC) spaces on the aesthetics of smile between laypeople and dental students. Materials and Method: It was a cross-sectional study conducted at Karachi Medical Dental College. A digital photograph of a girl’s posing smile using image editor (Adobe Photoshop version 7), displaying dentition from 1st molar to 1st molar with changed Buccal Corridor (BC), has been created. Buccal Corridor have been digitally modified by 5% rise, assessed with internal commissural width from 0% to 25%. Total seventy-five dental students studying in final year and 75 laypersons of age >19 years of either gender were included in the study. The rating was done using visual analog scale (VAS) to assess the esthetic of each smile. The score for esthetic was classified from 0 to 100, the lowest being 0 and the highest esthetic rating being 100. SPSS version 23 was used to analyze data. Results: The medium broad smile (15% BC) was rated highest by the dental students whereas broad smile (5% BC) was rated highest by the laypeople. There was statistically difference was observed between the rating of dental students and laypeople for narrow smile (25% BC), medium smile (15% BC), broad smile (5% BC) and medium-broad smile (10% BC) (p<0.05). Conclusions: The Buccal Corridor space is seen by laypeople and dental students as an imperative factor in shaping their esthetic assessments. Both the dental students and the dental students favored medium to wider smiles.
