Photographic and Manual Evaluation of Golden Percentage and Recurrent Aesthetic Dental Proportion in Aesthetic Smiles

Abstract

BACKGROUND Due to increased aesthetic demands, the dentist should rely on the aesthetic principles that exist in nature so as to reproduce or integrate them in humans to mimic the essential beauty. The Golden proportion, Golden percentage and recurrent aesthetic dental proportion are some of the commonly used guidelines by the dental profession for better aesthetic proportion in dentition. AIM The aim of the present study was to investigate the existence of Golden Percentage and Recurrent Aesthetic Dental proportion between the widths of maxillary anterior teeth in individuals with natural aesthetic dentition. METHODS AND MATERIAL This study was conducted on 60 dental students with an aesthetic smile (30 males and 30 females) with ages ranging from 18 to 30 yrs. by obtaining prior consent. An impression of upper arch was made with alginate impression material and standardized facial photographs were obtained from each individual. Analysis was performed by operator on cast using Dial caliper and on photographs using Corel Draw software. The existence of Golden Percentage and Recurrent Aesthetic Dental proportion was investigated. The data was statistically analysed by student's paired 't' test. RESULTS This study has shown that golden percentage is observed only in the lateral incisors and is not applicable to central incisor which showed Golden percentage of 21.7% and canine which showed 13%. There was no evidence to support the existence of RED proportion. CONCLUSION Further studies need to be carried out on a larger population with different stereotypes to prove the existence of Golden percentage and RED proportion in the Indian population.

“…3) (Table 6). The mean width ratios recorded in this study are above the ranges described by previous authors in the right CA/LA ratios of all participants (86.86% vs 66.00-85.72%) [11,15,19,24,26,29] and of men (88.46% vs. 74.14-86.00%) [8,15,16,25,[27][28][29]. These ratios are below the range in left LA/CE of women (66.13% vs. 67.00-74.08%) and right LA/ [8,15,16,25,[27][28][29].…”

“…The results of previous works that studied GP, RED and Preston's proportion are reflected in Table 6 [8,11,15,16,[24][25][26][27][28][29]. Table 7 shows the mean width of the maxillary anterior teeth in the ICW found in previous studies [8,[15][16][17]24,25,29,30].…”
