Evaluating the validity of recurring esthetic dental proportion in young adults

Abstract

An important aspect of cosmetic dentistry is developing a geometric or numerical proportion to associate the consecutive width of maxillary anterior teeth. New hypotheses in this area include the Golden proportion, golden percentage, and the recurrent esthetic dental (RED) proportion. This study used digital photos and computer analysis to examine the existing RED proportion associated with the widths of maxillary anterior teeth in people with permanent dentition. Sixty young adults (28 males and 32 females) were photographed from the front. Digital measurements were taken of all maxillary anterior teeth. To determine whether the RED proportion exists in the permanent dentition, the mean width proportion of the maxillary lateral incisor to central incisor and maxillary canine to lateral incisor was established. The average lateral incisor to central incisor width proportion of the right and left side was determined to be 70% and 71%, respectively. The average canine to lateral incisor width proportion was determined to be 80% and 78%, respectively. The maxillary anterior teeth’s consecutive widths did not exhibit RED proportions in the data that were examined. People’s anterior tooth proportions differ based on their race and ethnicity. Thus, the RED ratio is not the only standard for rebuilding aesthetically acceptable smiles globally.
