PREVALENCE OF GOLDEN PROPORTION AND RECURRING ESTHETIC DENTAL PROPORTION IN TELANGANA POPULATION: A CROSS - SECTIONAL STUDY

Abstract

Aim: The aim of this study was to assess the prevalence of golden proportion and recurring esthetic dental proportion in Telangana population.

Materials and Methods: This study was executed in the department of Prosthodontics wherein the volunteers aged between 18 and 25 years, were selected to participate in the study. Subjects were seated comfortably and instructed to assume the Natural Head Position and Photographs were taken following the American Academy of Cosmetic Dentistry (AACD) guidelines. All images were saved in JPEG format at 300 dpi resolution and imported into Adobe Photoshop CC for digital analysis. The mesiodistal width of each tooth was then calculated in pixels. The collected data were entered into a spreadsheet and subsequently analyzed using statistical software. To evaluate the Golden Proportion, the measured width of the central incisor was multiplied by 0.618 (61.8%) and compared with the width of the adjacent lateral incisor. All data was analyses for statistical evaluation to determine the prevalence and consistency of esthetic dental proportions.

Statistical Analysis and Results: Statistical Analysis was done with Statistical Package for Social Sciences [SPSS] for Windows. The measured mean width of the right and left central incisors was 7.94±0.58 mm and 7.98±0.57 mm respectively. Paired t-test analysis revealed no statistically significant difference. When seeing the prevalence of Golden Proportion, the mean ratio was 75.4±10.7% on the right side and 74.3±9.5% on the left side, with an overall combined mean of 74.9±10.1%. When seeing the RED Proportion, Chi-square test revealed that the proportion of ratios within the RED range was significantly higher than those outside the range (p<0.001), indicating that RED proportion is more commonly observed in the study population. When seeing the gender comparison of the lateral/central incisor width ratio on the right side, the mean ratio among males was 76.2±11.3%, while among females it was 74.9±10.5%.

Conclusion: Authors concluded and expressed excellent bilateral symmetry in mesiodistal teeth dimensions, with no statistically significant differences between right and left sides. Gender-based comparison also revealed no significant variation in lateral-to-central incisor width ratios, indicating that anterior tooth proportions in the Telangana population were largely independent of side and gender.
