上海市区成人牙本质敏感流行病学调查

The epidemiology of dentine hypersensitivity among adults in Shanghai municipality

目的:了解上海市区成人牙本质敏感的现状,为牙本质敏感的诊断、预防以及治疗提供依据。方法:采用多阶段分层等容量随机抽样调查,对上海市区1320名成年人进行牙本质敏感的现场检查,使用SPSS12.0软件包对数据进行分析。结果:上海市区成人牙本质敏感的检出率为32.58%,其中男173例,女257例,男女比例为1∶1.49。牙本质敏感最好发于前磨牙,其次为第一磨牙,敏感好发牙面部位以牙颈部为主。95.58%的敏感人群伴牙龈退缩,其中92.75%敏感部位在牙颈部者出现牙龈退缩。结论:上海市区成人牙本质敏感检出率与其他国家相比处于中等水平。牙龈退缩是引起牙本质敏感的主要原因。

PURPOSE： The aim of this study was to investigate the prevalence of dentine hypersensitivity among adults in Shanghai municipality, and to provide data for diagnosis and prevention of dentine hypersensitivity. METHODS： The representative samples were selected by multi-stage,stratified and random sampling,which included 1320 subjects. Clinical examination was made to confirm the diagnosis of dentine hypersensitivity. SPSS 12.0 software package was used for statistical analysis. RESULTS： The prevalence of dentine hypersensitivity was 32.58%, 173 patients were male and 257 were female, giving an overall male：female ratio of 1：1.49. The premolars were most affected, followed by the first molars. The most vulnerable surface of the teeth involved with sensitivity was the cervical area. 95.58% of the patients with dentine hypersensitivity had gingival recession. 92.75% of teeth with cervical dentine hypersensitive had gingival recession. CONCLUSIONS： A medium prevalence figure is found in the present study in comparison with other countries. Gingival recession is the most important etiological factor of dentine hypersensitive.
