Abstract
|
|
|
Objective: This study aimed to investigate the smile shapes that are considered attractive as well as smile consciousness, among women in Japan, the U.S.A., and Indonesia.
Methods: In total, 262 women completed a survey on attitudes toward smile shapes, based on posed smile photographs. The attractiveness of 12 smile patterns and smile consciousness was compared among participants from the three countries.
Results: The smile shapes that Japanese women found attractive had the corners of the mouth higher than the center of the upper lip, with the teeth and gingiva of the maxilla exposed (V shape). However, Americans and Indonesians preferred smiles with mouth corners aligned to the center of the upper lip and higher than the center of the lower lip, with the teeth and gingiva of the maxilla and mandible exposed (cup shape). A significantly higher proportion of respondents in Japan said they covered their mouth with their hand when smiling, and that they lacked confidence in their smiles. The primary reason for the lack of confidence was tooth alignment among Japanese, tooth color among Americans, and both tooth alignment and gingival exposure among Indonesians.
Conclusion: Desirable smile shapes and smile consciousness differed significantly among the three countries.
