THE INFLUENCE OF GENDER ON ESTHETIC PERCEPTION OF MAXILLARY LATERAL INCISOR WIDTH RATIOS IN LAYPEOPLE

Abstract

This research aimed to investigate the influence of gender on the esthetic perception of the width ratios of maxillary lateral incisors. A total of 60 participants, equally divided between males and females, participated in the study. Data collection was conducted through an online questionnaire. A standard smile was selected, and the lateral-to-central incisor ratio was adjusted to achieve a 70% RED proportion, or 7:10, to serve as the standard smile. Subsequently, only the size of the maxillary lateral incisors was modified to create seven different ratios: 5.5:10, 6:10, 6.5:10, 7:10, 7.5:10, 8:10, and 8.5:10. Participants rated the esthetic appeal using a Numerical Rating Scale. The results showed that the 7:10 ratio received the highest esthetic scores from both male and female groups, followed by the ratio 7.5:10 while the 5.5:10 ratio received the lowest scores. It could be concluded that gender did not significantly influence the esthetic perception of maxillary lateral incisor ratios in laypeople.
