壮族青年牙外观满意度及正畸治疗需要指数的调查研究

Studies on the satisfaction with general dental appearance and the index of orthodontic treatment need of Zhuang youths

目的:通过对广西壮族青年行问卷调查确定牙外观满意度、测量牙科美学指数(DAI)确定正畸治疗需要量,从而为口腔卫生资源的合理配置提供参考依据。方法:随机抽取77名壮族青年行牙外观满意度问卷调查,制取石膏模型并测量DAI。结果:广西壮族青年具有较高的牙外观满意度(男性80.8%,女性70.6%),较大的正畸治疗需要量(男性76.9%,女性84.3%)。错牙合畸形的主观评价均不高于50%。壮族女青年(96.1%)较男青年(73.1%)更介意牙齿被染色。部分壮族青年更愿意通过牙齿美白提高牙外观(男性50.0%,女性74.5%)。结论:广西地区部分壮族青年未能客观地认识自身牙外观、对改善牙外观的治疗方式了解不足、正畸治疗需要量较大,应增大对该群体的口腔卫生资源调配及错牙合畸形的防治力度。

Objective： To confirm the need of orthodontic treatment of Zhuang youths by conducting a satisfaction ques- tionnaire survey of general dental appearance on them and measuring their Dental Aesthetic Index （DAD in order to provide references for reasonable allocation of oral health resources. Methods： 77 Zhuang youths were selected randomly to take part in the satisfaction questionnaire survey of general dental appearance and their study plaster models were made to measure the DAI. Results： High rates of satisfaction of general dental appearance（male 80.8%, female70.6%） and great demand for orthodontic treatment（male76.9%, female 84.3%） of Zhuang youths in Guangxi were demonstrated in our survey. Subjective evaluation of malocclusion was no more than 50%. Dissatisfaction of discolored teeth was significantly higher in female （96.1%） than in male （73.1%）. Tooth whitening was the treatment most demanded by Zhuang youths （male 50.0%, female 74.5%）. Conclusions： The dental appearance could not be recognized objectively by most of Zhuang youths in Guangxi. They also lack of knowledge of the treatments that can improve the appearance of their own teeth, and their need for or- thodontic treatments was large. Therefore, we should increase the allocation of oral health resources and enhance the pre- vention of malocclusion.
