Psychosocial Impact of Dental Esthetics on Quality of Life in Adolescents Association with Malocclusion, Self-Image, and Oral Health-Related Issues

Objective: To test the hypothesis that several dimensions of the self-perceived psychosocial impacts of dental esthetics are not associated with grades of malocclusion, oral health-related quality-of-life measures, and body self-image in adolescents. Materials and Methods: This cross-sectional study included a convenience sample of 301 adolescents (mean age 16.1 +/- 1.8 years, 58.1% female subjects). Demographic data were collected and dental conditions were assessed. The Dental Aesthetic Index (DAI) was used for assessment of malocclusion and determination of orthodontic treatment needs. The short form of the Oral Health Impact Profile (OHIP-14), the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ), and the Body Satisfaction Scale (BSS) were used to measure adolescents' self-perceived variables. Results: All variables (DAI, OHIP-14, and BSS) were correlated with PIDAQ (P <.001). Stepwise multiple regression analysis revealed significant associations (P <.001) of independent variables with the total score of PIDAQ (R-2 = 0.29) and dental self-confidence (R-2 = 0.30), social impact (R-2 = 0.14), psychological impact (R-2 = 0.23), and esthetic concern (R-2 = 0.13). Conclusion: The hypothesis is rejected. A broad range of adolescents' self-perceived impact of dental esthetics is influenced by severity of malocclusion, oral health-related quality of life, and body satisfaction.
