Abstract
AIM: To evaluate the perception of altered smile esthetics, including buccal corridor width, gingival display, and smile arc, among general dentists and laypersons. MATERIALS AND METHODS: A total of 40 evaluators (20 dentists and 20 laypersons) assessed nine digitally modified smile images representing variations in buccal corridor, gingival display, and smile arc. Images were rated using a 5-point Visual Analog Scale, where 1 indicated the most attractive and 5 the least attractive. The Mann-Whitney U test was used for intragroup comparisons, while the Wilcoxon rank test assessed intergroup differences (P < 0.05). RESULTS: Both groups rated smiles with no buccal corridors as the most esthetic (1.60 dentists, 1.35 laypersons), while excessive buccal corridors were least favored. Gingival display of 0 mm was preferred by both groups (1.55 dentists, 1.35 laypersons), while 3-mm gingival display was least attractive. Dentists preferred a consonant smile arc (1.50), while laypersons were less critical (1.70). CONCLUSION: Although both groups shared similar esthetic preferences, dentists were more critical of smile variations than laypersons. These differences highlight the need for patient-centered esthetic treatment planning, considering professional judgment and patient expectations.
