Esthetic Smile & Its Relationship with Anterior Teeth Proportion: A Clinical Study

Abstract

The present study was conducted with the aim to evaluate the existence of golden percentage, golden proportion and red proportion in maxillary anterior teeth of students in Triveni institute of dental sciences, Hospital & Research centre. Bilaspur, Chhattisgarh. A standardized profile image of each subject’s face was taken using a digital camera (NIKON DSLR) and transfer to Adobe Photoshop. The esthetic evaluation of subjects’ smile was done using the profile image (facial midline, smile line, lip line and line between the commissures). Impressions of the Maxillary teeth will be made by perforated dentulous metallic tray with Alginate-Irreversible hydrocolloid material and casts will be poured from Type 3 gypsum product and measurement of maxillary anterior teeth is done by digital vernier caliper followed by drawing of grids for the perceived widths of maxillary anterior teeth and the data of each tooth will be recorded. Using the formula of different anterior teeth proportion, the golden percentage, golden proportion and red proportion was calculated. The data obtained were fed in SPSS software for statistical analysis. Statistical highly significant difference (p ≤ 0.001) evidenced more number of males with golden proportion in comparison to females whereas no statistical significant difference (p=0.693) for golden percentage and red proportion (p=0.795) is revealed between male and female subjects. Among all the subjects with esthetic smile, highly significant difference (p ≤ 0.001) existed for golden percentage and golden proportion. In contrary insignificant difference (p=0.054) was observed with red proportion. Clinical results showed statistical significant difference in males with esthetic smile (p ≤ 0.05) for presence of golden percentage, and golden proportion and no significant result for red proportion when compared with male subjects having unesthetic smile. The same results were obtained for females with esthetic smile in comparison to unesthetic smile. Esthetic smile was significantly higher (p=0.01) among females as compared to males.
