目的调查辽宁省农村20~<70岁氟牙症人群牙本质敏感的患病状况及其相关危险因素，为牙本质敏感的预防和治疗提供依据。方法2009-2010年在辽宁省新民市氟牙症病区采用随机区组抽样的方法，对800名20~<70岁居民进行牙本质敏感的临床检查和问卷调查，应用氟离子选择电极法检测居民饮水氟质量浓度，采用Logistic回归分析牙本质敏感的危险因素。结果当地居民饮水氟质量浓度为1.15~1.50 mg/L，氟牙症患病率为95.0%；800名20~<70岁成人完成了牙本质敏感的临床检查和问卷调查，79人被检出牙本质敏感，患病率为9.9%，男女之间差异无统计学意义（P>0.05）。敏感最好发牙位为下前牙，其次是第一磨牙；敏感好发牙面为唇颊侧牙颈部根面暴露处。牙刷使用时间过长是本次调查人群牙本质敏感的危险因素（OR=2.210）。在敏感人群中无人采取治疗措施或去医院、诊所咨询。结论农村人群在饮水氟质量浓度为1.15~1.50 mg/L时，氟牙症发病率高，但牙本质敏感患病率较低，此时牙刷使用时间是危险因素。

Objective To investigate the prevalence and risk factors of dentin hypersensitivity in endemic fluorosis rural area of Liaoning Province. Methods Random sampling methods were performed,and 800 adults living in the same en-demic fluorosis county in Liaoning province aged 20- <70 were selected. A structured questionnaire and a clinical ex-amination on dentin hypersensitivity were used in the survey. The relative risk factors of dentin hypersensitivity were ana-lyzed. Fluoride ion selection electrode was used to determinate fluoride content in drinking water. Results The fluoride concentration in drinking water in the county was between 1.15 mg/L and 1.50 mg/L;the prevalence of dental fluorosis was 95.0%. Totally 800 20- <70 years old subjects completed a structured interview and underwent a clinical examina-tion on dentin hypersensitivity. Among them,79 were found to have dentin hypersensitivity,the prevalence being 9.9%. There was no difference between male and female. The commonest teeth affected were the lower front teeth,followed by the first molar. The exposed root surface was the most commonly affected position. The time of using a tooth brush was the risk factor for dentin hypersensitivity(OR=2.210). Nobody in sensitive group had taken measurements or gone to see the dentist. Conclusion The prevalence of dentin hypersensitivity may be decreased and the time of using a tooth brush is the risk factor when the drinking water fluoride concentration is between 1.15 mg/L and 1.50 mg/L.
