Assessment of smile architecture and pink aesthetics: A successful methodology in cosmetic dentistry

Abstract Objective: Aesthetic restorative treatment plays a very essential role in smile appearance. The aim of this study is to assess smile architecture and periodontium outlook for aesthetic evaluation. Materials and Methods: One hundred subjects (50 women and 50 men) aged from 18 to 62 years were enrolled and photographed. Standardized digital photographs were taken to assess smile architecture and gingival biotype during regular and expanded smile. Smile was assessed on the basis of following criteria: 1) extremely high smile line; 2) high smile line; 3) moderate smile line; and 4) low smile line. Patients were also classified by age group and gender as follows: a) males aged from 18 to 30 years; b) females aged from 18 to 30 years; c) males aged 31 years and above; and d) females aged 31 years and above. Gingival biotype was analysed using visual assessment method. Statistical analysis was performed using Chi-square test to assess differences between groups. Results: Assessment revealed that subjects with regular smile had the following: Class 1, 2%; Class 2, 10%; Class 3, 45%; and Class 4, 43%. With expanded smile, subjects revealed the following: Class 1, 9%; Class 2, 13%; Class 3, 58%; and Class 4, 20%. The periodontal outlook was more prevalent in the expanded and regular smile for younger age group than the older one. Age and gender influenced the position of the smile architecture. About 80% of the subjects were concerned of aesthetics. Conclusion: Assessment of smile architecture and pink aesthetics becomes mandatory for both regular and expanded smile for both the genders.
