骨性错[牙合]患者颌面部美观的自我评价

Self-evaluation of dentofacial esthetics in skeletal malocclusion patients

目的调查骨性错[牙合]患者以及正常人群对牙、颌面部美观的自我评价是否存在差异。方法受试者分为3组：骨性错[牙合]Ⅱ类组、骨性错[牙合]Ⅲ类组以及对照组。3组间性别、年龄比较，差异无统计学意义。通过问卷调查的方式．分别对自己牙齿和面部美观的满意度进行自我评估。使用方差分析、直线回归和Logistic回归进行统计学处理。结果骨性错[牙合]患者对自己牙、颌面外形的满意度低于对照组（P〈0．05）。骨性Ⅱ类错[牙合]患者和所有女性对她们的牙齿外形的满意度较低。其中牙齿的形状（44．5％）和前突（17．8％）是牙齿外形满意度低的最主要原因。3组受试者中女性均比男性对自己的颌面部外观满意度低。最不满意的面部外观主要集中在颏部（53％）、面部轮廓（37％）以及微笑时牙齿显露的部位（33％）。骨性Ⅲ类错[牙合]患者比骨性Ⅱ类错[牙合]患者更渴望改变他们的侧貌。结论女性和骨性错[牙合]患者村他们的颌面美观满意度低。骨性Ⅱ类错[牙合]患者对他们牙齿美观满意度低，骨性Ⅲ类错[牙合]患者更关心他们的侧貌。

Objective To investigate the difference between the self-evaluation of patients with dental and facial esthetics in skelelal malocclusion and normal persons. Methods The subjects were divided into three groups： 62 patients with skeletal Class Ⅱ , 8,1 patients with skeletal Class Ⅲ, as well as 130 persons in control group. There was no obvious difference in gender and age among the three groups. Happiness with dental and facial appearance was assessed using questionnaires. Analysis of variance, linear regression and logistic regression were used for statistical analysis. Results Skeletal malocclusion patients were less happy with their dental appearance than control group. Class Ⅱ patients and women had lower happiness scores for their dental appearance. Among skeletal malocclusion patients, the shape （44.5 %） and prominence of their teeth （17.8 %） were the most frequent causes of concern. Older subjects, women, and skeletal malocclusion patients were less happy with their facial appearance. Most of them were dissatisfied with the facial appearance focused on the chin （53 % ）, facial contours （37 % ）, and the position of the teeth when smiling （33 %）. A greater proportion of Class Ⅲ subjects tban Class Ⅱ subjects wished to change their appearance. Conclusions The findings indicate that women and skeletal malocclusion patients have lower levels of happiness with their dentofacial appearance. Although Class Ⅱ patients exhibit the lowest levels of happiness with their dental appearance, there is some evidence tbat concerns and awareness about their facial profile are more pronounced among the Class Ⅲpatients.
