Evaluation of golden proportion between anterior teeth in pakistani population

Objectives: The prevalence of the golden proportion between the widths of maxillary anterior teeth varies among different populations and ethnic groups. As few studies has evaluated this relationship in Pakistani subjects. Therefore, the purpose of this study was to investigate the prevalence of the golden proportion in a group of Pakistani subjects.
Methods: Digital vernier caliper was used to record the width on 400 subjects of both sexes in the age group of 21 – 30 years. The dental casts of the selected individuals were used for the measurements. Alginate impressions were made and were poured in the hard stone .mesiodistal widthwas measured using vernier calipers . Mesiodistal widths (actual width) of central incisors, lateral incisors and canines were measured from the labial side using a sharp beaked vernier caliper positioned between the widest points of each tooth.
Frequency distribution of the subjects were calculated.Mean and Standard Deviations (SD) of the measured tooth widths were obtained. Pearson’s Correlation Coefficient was calculated to reveal linear association among the actual (contact-contact) width .
Results: There was a statistically significant correlation between the actual width and the apparent width , and between the predicted (golden) width and the actual width for the lateral maxillary incisor, while there was no significant correlation between the Golden (predicted) and the apparent width of the same tooth
Conclusions: golden proportion should not be considered as a decisive factor of determining dental attractiveness.It should be a range rather then a single value.
