Frequency of Golden Proportion and Golden Percentages in Maxillary Anterior Teeth Widths

Abstract

Objective: To determine the frequency of Golden Proportion and Golden Percentages in maxillary anterior teeth widths.

Study Design: A Cross-Sectional Descriptive Study

Place and Duration of Study: This study was conducted at the Department of Prosthodontics, FMH College of Medicine and Dentistry, Lahore from October 2015 till April 2016 for a period of six months.

Materials and Methods: Standardized digital photographs of 115 participants, of both genders were captured during smile displaying maxillary anterior teeth. The apparent tooth width of maxillary anterior teeth was measured with the help of the software. The calculations were done to determine golden proportion and golden percentages. The data was subjected to statistical analysis, (descriptive statistics and chi -square test, level of significance was set at p<0.05).

Results: The golden proportion was found to be existed  only 7% of the participants between the widths of right central incisor and right lateral incisor.Among them 2.6 % male and 4.3% female. The results revealed that golden percentages existed in maxillary anterior tooth widths in natrural dentition of  our population.The value of golden percentage for each maxllary anterior tooth is 22% for central incisors,15% for lateral incisors and 12% for canines of the total canine to canine width. There was statistically significant difference existed between the ages and genders for golden proportions and golden percentages.

Conclusion: The golden percentage theory can beutilized to develop proportion and symmetry in maxillary anterior teeth widths to achieve aesthetically pleasing restorations. It can be taken as an aesthetic guideline if the percentages of tooth widths are adjusted according to the ethnicity of the population.
