Resumo
Objective: To investigate the impact of the anterior teeth display during smiling (ATDDS) on the
self-perceived psychosocial impacts of malocclusion in adolescents.
Materials and Methods: This cross-sectional study included a convenience sample of 301
adolescents (mean age 16.1 years, SD 1.8 years; 58.1% female). Two instruments were used for
data collection: (1) the Dental Aesthetic Index (DAI) and (2) the Psychosocial Impact of Dental
Aesthetics Questionnaire (PIDAQ). In addition, ATDDS was assessed in posing smiling, and
adolescents’ satisfaction with their dental appearance was investigated. Data analysis included
descriptive statistics, Kruskal-Wallis test and Mann-Whitney U-test, Spearman correlation, and
multiple linear regression analysis.
Results: Significant associations were observed between independent variables (ATDDS, DAI
scores, and satisfaction with dental appearance) and total PIDAQ score (R 2 5 0.37) and dental
self-confidence (R 2 5 0.37), psychological impact (R 2 5 0.30), esthetic concern (R 2 5 0.20), and
social impact (R 2 5 0.15).
Conclusion: The excessive anterior teeth display during smiling may potentially influence the self-
perceived psychosocial impacts of malocclusion in adolescents depending on the severity level of
malocclusion and the self-reported satisfaction with dental appearance. (Angle Orthod.
