Objective: The objective of this study is to evaluate the psychosocial impact of dental aesthetics in undergraduate students in the People’s Republic of China and to investigate the association between normal orthodontic treatment needs, psychosocial impact of dental aesthetics, and desire for orthodontic treatment.
Materials and methods: A cross-sectional study was carried out in two universities in a city of the People’s Republic of China with 374 young adults aged between 19 years and 24 years. The students answered a Chinese version of the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) and addressed their desire for orthodontic treatment. Objective malocclusion severity was assessed with the Index of Orthodontic Treatment Need (IOTN). Statistical analysis was performed by the SPSS software (Version 15.0).
Results: There was no statistical sex difference in relation to the dental health component of IOTN (P=0.893) and PIDAQ scores (P=0.06), but it was found that the desire for orthodontic treatment was significantly stronger among females. The total and subscale PIDAQ scores and malocclusion severity differed significantly among the five grades of desire (P<0.01). Significant positive correlation was found among desire for orthodontic treatment, IOTN-dental health component grades, and total or subscale PIDAQ scores (P<0.01). High correlation was found between desire and PIDAQ score (r=0.93).
Conclusion: The desire for orthodontic treatment is higher among female young adults who have the same orthodontic treatment needs compared to males. The desire for orthodontic treatment has high positive correlation with PIDAQ scores and increases with the increase in self-perceived psychosocial impacts of malocclusion and the needs for orthodontic treatment.
