Evaluation of the Prevalence of Golden Percentage Among Dental Students Using a Digital Smile Design Approach
Abstract: Background: Smile esthetics plays a significant role in facial attractiveness and social confidence. Various mathematical concepts have been proposed to establish ideal anterior dental proportions, among which Snow?s golden percentage remains one of the most discussed concepts in esthetic dentistry. According to this theory, the visible widths of maxillary anterior teeth should follow a fixed percentage distribution to achieve an ideal smile. However, the applicability of this concept among different populations remains controversial. Aim: To evaluate the prevalence of Snow?s golden percentage among dental students with esthetically pleasing smiles using a digital smile design approach. Materials and Methods: The present observational cross-sectional study included 25 dental students of KVG Dental college and Hospital, Dakshina Kannada aged between 18 and 25 years with esthetically pleasing smiles. Subjects with missing teeth, carious lesions, crowding, spacing, restorations, or previous orthodontic treatment were excluded. Intraoral scanning of the maxillary arch was performed to obtain digital models. The apparent mesiodistal widths of maxillary anterior teeth were measured using MeshLab software. The percentage contribution of each anterior tooth relative to the total width of the six anterior teeth was calculated and compared with Snow?s proposed golden percentage values. Descriptive statistical analysis including mean and standard deviation was performed. Results: The mean percentage values for the right maxillary canine, lateral incisor, and central incisor were 8.164%, 14.314%, and 18.108%, respectively. On the left side, the mean percentage values for the central incisor, lateral incisor, and canine were 18.612%, 14.796%, and 8.34%, respectively. None of the evaluated subjects demonstrated the exact golden percentage proportions proposed by Snow. Conclusion: The present study demonstrated that Snow?s golden percentage was not consistently observed among dental students with esthetically pleasing smiles. These findings suggest that smile esthetics may not be solely dependent on strict mathematical proportions and highlight the importance of individualized smile design.
