The aim of the present study was to explore the putative relationship between dental aesthetics and oral health-related quality of life (OHRQoL), taking into consideration the potential direct and moderating influence of private and public self-consciousness. The subjects of this cross-sectional survey were 148 university students. Dental aesthetics were assessed by means of the aesthetic component (AC) of the Index of Orthodontic Treatment Need (IOTN). OHRQoL was estimated using a modification of the scales 'social appearance concern' and 'appearance disapproval', and a novel dental self-confidence scale. In addition, the private and public self-consciousness scales were used. Two-factor analyses of variance were carried out with high and low levels of dental aesthetics and private and public self-consciousness as the independent variables and the OHRQoL scales as the dependent variables. It was found that dental aesthetics had a direct effect on all OHRQoL scale values. Private self-consciousness was related to social appearance concern, while public self-consciousness was associated with both social appearance concern and appearance disapproval. An interaction effect was identified which showed that the impact of dental aesthetics on social appearance concern was stronger in respondents with high private and public self-consciousness than in low scoring subjects. The findings of the study suggest that minor differences in dental aesthetics may have a significant effect on perceived OHRQoL. This effect was more significant in subjects with high self-consciousness.
本研究的目的是探讨牙齿美观与口腔健康相关生活质量（OHRQoL）之间的假定关系，同时考虑到个人和公众自我意识的潜在直接和调节影响。这项横断面调查的对象是148名大学生。通过正畸治疗需求指数（IOTN）的美学成分（AC）评估牙齿美观。使用“社会外貌关注”和“外貌不满”量表的修改版以及一个新的牙齿自信心量表来估计OHRQoL。此外，还使用了个人和公众自我意识量表。以牙齿美观和个人及公众自我意识的高低水平作为自变量，以OHRQoL量表作为因变量进行双因素方差分析。结果发现，牙齿美观对所有OHRQoL量表值都有直接影响。个人自我意识与社会外貌关注有关，而公众自我意识与社会外貌关注和外貌不满都有关。发现了一种交互作用效应，即牙齿美观对社会外貌关注的影响在个人和公众自我意识高的受访者中比在得分低的受试者中更强。研究结果表明，牙齿美观的微小差异可能对感知到的OHRQoL有显著影响。这种影响在自我意识高的受试者中更为显著。
