目的了解白银市工业区域人群口腔健康状况及恒牙氟牙症流行状况,分析流行因素,探讨防治对策,为白银市口腔卫生保健工作提供信息支持。方法采用多阶段、分层、等容量、随机抽样的方法,抽取白银市工业区域城乡12岁常住人口480人,男女各半。按照《第三次全国口腔健康流行病学调查方案》中临床氟牙症的检查方法和标准,检查全口恒牙牙冠氟牙症情况。数据采用SAS软件统计,患病率比较采用χ2检验。结果 12岁人群氟牙症患病率为31.88%,氟牙症指数为0.3,氟牙症处于流行边缘。尿和水的中氟含量均在正常范围。结论白银市工业区域氟牙症患病率和氟牙症指数均高于全国水平,处于流行边缘,推测与工业区域空气氟污染和环境氟污染有关。
Objective To understand the oral health status of population in the industrial area of Baiyin City and the epidemic situation of dental fluorosis, analyze the epidemic factors and discuss the prevention and treatment measures, and provide information support for the oral health care in Baiyin City.
