Abstract

Introduction: The aim of this study was to evaluate the psychosocial impact of dental esthetics for adults seeking orthodontic treatment.

Methods: The Chinese version of the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) was administered to 393 adults, aged 18 to 30 years. The participants were divided into 2 groups: an intervention group (received orthodontic treatment) and a control group (rejected orthodontic treatment). Baseline malocclusion severity was assessed using the Index of Orthodontic Treatment Need (IOTN).

Results: The Wilcoxon signed rank test showed no statistically significant difference between the groups for the dental health component (DHC) of the IOTN (P = 0.134). Total and subscale PIDAQ scores of the intervention group were higher than those of the control group and differed significantly in each group among the 4 IOTN-DHC grades; self-confidence scores in the control group (F = 1.802; P>0.05) were the exception. Correlations between the PIDAQ scores and the IOTN-DHC grades were strong in each group. DHC grades, psychological impact, social impact, and aesthetic concern had significant impacts on patients accepting orthodontic treatment.

Conclusions: The psychosocial impact of dental esthetics played an important role in the decision-making process of adults seeking orthodontic treatment. Importantly, participants with low self-awareness of the potential psychosocial impact rejected orthodontic treatment, despite the need for severe normative treatment.
