Comparative Evaluation of Golden Proportion, Recurring Esthetic Dental Proportion and Golden Percentage in Himachal Demographic

Aim: The purpose of this study was to comparatively evaluate the validity of Golden Proportion, Recurring Esthetic Dental (RED) proportion and Golden Percentage in maxillary anterior teeth in population of Himachal Pradesh.

Methods and Materials: Dentulous stone casts of maxillary arch were made of the subjects who met the inclusion criteria. Conditions for inclusion criteria included that the individuals:

1) should be of Himachali origin with agreeable smiles

2) have well aligned anterior dentition

3) should be between age group of 20-40 years

Total of 200 students representing Himachal Pradesh population were included. Measurements were done for the spaces in the grids using the digital caliper.

Results:

The Golden Proportion ratio of 1.3 and 1.4 were more commonly observed in 27.5% and 40% respectively than 1.618 which was observed in 5.5% under study of the population.
A Paired sample t-test showed there was no significant gender based difference in Lateral/Central incisor Red Proportion. (P-value>0.05) except for the Canine/Lateral Red Proportion. (P-value<0.05).
The Golden Percentage for males in central and lateral incisors and canine was 22.48%, 15.96% and 11.08% respectively. The mean value for females in central and lateral incisors and canine was 22.72%, 16.25% and 10.97% respectively.
Conclusions: Golden percentage could be used for aesthetic correction and was found to be more applicable in the population included in this study. Golden percentage could be used for aesthetic correction and are more applicable to natural dentition in the population of Himachal Pradesh.
