Hard Tissue Significance to Divine Proportion.

Background: Facial proportions are of interest in orthodontics. Leonardo Da Vinci had shown the relation between harmony and proportion when he discussed about "proportional beauties of an angelic face." The purpose of this study was to assess the influence of hard tissue on facial attractiveness on young attractive North Indian women. Materials and Methods: Thirty attractive young women out of 102 were selected (of age group 18 to 26 years) representing the population of North India, by a panel of selectors from various different backgrounds. Divine proportions were evaluated by using Ricketts method of divine proportion analysis on lateral cephalogram. Results: The subjects showed golden proportions on said parameters. The "t" test is significant at t = 3.65 very highly significant for linear facial height and the width ratios. Conclusion: On hard tissue, the ratios were found to be very close to the divine proportion in vertical and transverse dimension. The soft tissue of attractive face also exhibits divine proportion.
