Abstract

This study aimed to determine the characteristics of maxillary anterior tooth shape selection in esthetic smile design among young adults in 2025 in Hanoi. A cross-sectional study was conducted on 535 students aged 18 - 30 years old at VNU University of Medicine and Pharmacy, who were divided into two groups: first- and second-year students, and fifth- and sixth-year students. Participants scored each designed image using a VAS 0-10 scale through an online survey based on image sets generated from the Exocad smile design library. The results showed that the selection of maxillary anterior tooth shapes in esthetic smile design differed significantly between males and females, as well as between student groups with different levels of background knowledge in esthetics. The shape of the maxillary central incisors and the prominence and height of the canine cusps played a decisive role in overall smile perception. Manually crafted, personalized designs were associated with higher satisfaction levels, and their integration with 3D digital models is recommended to achieve more accurate esthetic decision-making.
