What is The Influence of Different Tooth Proportions Obtained Using Digital Smile Design on the Perception of Smile Esthetics about?

## Abstract ## Objective The aim of this study is to examine the effect of designs using different esthetic dental proportions made with a digital smile design program on the esthetic perception of individuals of different ages, genders and educational statuses. ## Materials and Methods Different smile designs were made on facial photos taken of a female and male model using a smile design program. Four different dental proportions (golden proportion [GPR], golden percentage [GPE]), Preston proportion [P] and recurring esthetic dental proportion [RED]) and two different tooth shapes (oval and square) were used. Images with 16 different smile designs were presented to 4th and 5th‐year students of a faculty of dentistry, dentists, specialist dentists and laypersons for scoring. ## Results The gender of the participants did not affect the scores given (__p__ > 0.05), and participants over the age of 30 and lay people had higher scores (__p__ < 0.05). The GPR design was scored lower than RED when all designs were subdivided by tooth shape and gender (__p__ < 0.001). ## Conclusions The esthetic perceptions of people of different ages and dentistry education levels may differ from each o
