Malocclusion has a psychological impact related to the patient's age. It also influences the quality of life. This research aims to test the null hypothesis that there is no association between the self-perceived psychosocial impacts of dental aesthetics with the severity of malocclusion, oral health-related quality of life (OHRQoL), and self-image of the body in young adults seeking orthodontic treatment.
A convenience sample of young adults between 19 and 30 years old was selected for the study. The severity of malocclusion and orthodontic treatment needs were evaluated using the Dental Aesthetic Index (DAI). The Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ), Oral Health Impact Profile-14 (OHIP-14), and Body Satisfaction Scale (BSS) were used to evaluate the self-perceived effects of malocclusion.
The Kruskal-Wallis test is used to analyze the distribution of components with different grades of DAI. Spearman's correlation test evaluated the correlation between independent variables and their domains. The study utilized stepwise multiple linear regression analysis to assess the predictive value of independent factors on the PIDAQ and its domains.
A total of 181 subjects with a mean age of 24.4 ± 1.5 years, 42% males and 58% females, participated in this study. There was a significant correlation (p < 0.05) between all variables (OHIP-14, DAI, and BSS) and PIDAQ. There were significant correlations between the independent variables and the total score of PIDAQ (R2 = 0.16), psychological impact (R2 = 0.09), and social impact (R2 = 0.18), as well as dental self-confidence (R2 = 0.21) and aesthetic concern (R2 = 0.16).
In young adults, the self-perceived impact of dental aesthetics is moderated by the severity of malocclusion, oral health-related quality of life, and body satisfaction. The null hypothesis is rejected.
错牙合畸形对患者心理的影响与患者年龄有关。它还会影响生活质量。本研究旨在检验零假设，即在寻求正畸治疗的年轻成年人中，牙齿美观的自我感知心理社会影响与错牙合畸形的严重程度、口腔健康相关生活质量（OHRQoL）以及身体自我形象之间不存在关联。
选取了19至30岁的年轻成年人作为便利样本进行研究。使用牙科美学指数（DAI）评估错牙合畸形的严重程度和正畸治疗需求。采用牙齿美学心理社会影响问卷（PIDAQ）、口腔健康影响量表-14（OHIP-14）和身体满意度量表（BSS）来评估错牙合畸形的自我感知影响。
采用Kruskal-Wallis检验分析不同DAI等级成分的分布情况。Spearman相关性检验评估自变量与其领域之间的相关性。本研究利用逐步多元线性回归分析来评估独立因素对PIDAQ及其领域的预测价值。
共有181名受试者参与了本研究，平均年龄为24.4±1.5岁，男性占42%，女性占58%。所有变量（OHIP-14、DAI和BSS）与PIDAQ之间均存在显著相关性（p<0.05）。自变量与PIDAQ总分（R2 = 0.16）、心理影响（R2 = 0.09）、社会影响（R2 = 0.18）以及牙齿自信心（R2 = 0.21）和美学关注度（R2 = 0.16）之间存在显著相关性。
在年轻成年人中，牙齿美观的自我感知影响受到错牙合畸形严重程度、口腔健康相关生活质量和身体满意度的调节。零假设被拒绝。
