济宁市农村成人牙本质敏感的流行病学调查

An epidemiological survey of dentine hypersensitivity of rural adults in Ji'ning City

目的了解山东省济宁市农村成人牙本质敏感的流行状况及影响因素,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,对山东省济宁市农村1 200名成年人进行牙本质敏感的问卷调查及现场口腔检查,使用SPSS 13.0软件包对数据进行分析。结果山东省济宁市农村成人牙本质敏感依靠问卷确诊牙本质敏感的患病率为43.25%,通过临床检查为35.68%,女性患病率高于男性,有显著性差异（P〈0.01）。冷刺激是牙本质敏感最常见诱发因素（63.97%）。＂女性＂、＂经常吃煎饼＂、＂采用横刷法刷牙＂、＂存在胃肠道返酸症状者＂可能是牙本质敏感的危险因素。牙本质敏感最好发于前磨牙,其次为第一磨牙。50~59岁为牙本质敏感高发期,敏感好发牙面部位以牙颈部为主,82.44%的敏感人群牙龈存在附着丧失。结论山东省济宁市农村成人牙本质敏感广泛存在,口腔专业人员应尽快加强牙本质敏感预防和治疗措施的宣传。

Objective To investigate the prevalence and risk factors of dentine hypersensitivity of rural adults in Ji＇ning City,Shandong Province,and to provide the basis for diagnosing,preventing and treating the disease. Methods 1200 adults from the rural areas of Ji＇ning were selected by multi-stage,stratified and random sampling. The dentine hypersensitivity of all samples was surveyed with questionnaires and on-the-spot oral examinations. SPSS 13. 0 software was used for statistical analysis. Results According to the questionnaires,43. 25% of the rural adults in Ji＇ning City suffered from dentine hypersensitivity,while according to on-the-spot oral examinations,35. 68% of all suffered from dentine hypersensitivity. The prevalence rate of females was higher than of males（ P〈0. 01）. Cold was the most common stimulus for dentine hypersensitivity（ 63. 97%）. Females,high frequency of eating pancakes,horizontal toothbrushing,and acid regurgitation symptoms were probably the risk factors of dentine hypersensitivity. The premolar was the most commonly affected tooth by dentine hypersensitivity,followed by the first molar. The high-incidence age group of dentine hypersensitivity was 50-59 years old. The most common affected tooth surface was collum dentis,and 82. 44% sufferers had gingival attachment loss. Conclusions The dentine hypersensitivity of rural adults in Ji＇ning City is widespread. Therefore,the prevention and treatment for dentine hypersensitivity should be more promoted by dental professionals.
