【摘要】 目的 了解甘肃省某有色金属工业区儿童龋患状况，探讨环境对儿童患龋的影响，为开展牙病防治工作提供依据。方法 选择有色金属基地儿童作为研究对象，以临近非工业区作为对照区，采用随机抽样的方法分别抽取有色金属工业区与非工业区5岁和12岁儿童各200名，共800名，调查儿童龋病患病状况、口腔卫生状况和12岁儿童氟牙症状况，并测定当地饮水氟质量浓度。结果 工业区和对照区5岁组儿童龋病发病率差异无统计学意义，工业区12岁组儿童龋病发病率显著高于对照区同组水平，且氟牙症指数处于流行边缘；工业区2组儿童的菌斑指数显著低于对照区；工业区SiC(显著性龋均指数)高于对照区；两地水氟质量浓度均小于1.0 mg/L。结论 有色金属工业区环境污染可能是当地儿童龋病发病的诱发因素之一。

【Abstract】 Objective To evaluate the prevalence of dental caries for children living in nonferrous metal industrial areas and non-industrial areas in Gansu province and to provide evidence for oral health promotion. Methods By use of random sampling，200 5-year-old and 200 12-year-old children from nonferrous metal industrial areas and the same number children from non-industrial areas were examined，which included conditions of dental caries，oral hygiene and dental fluorosis in 12 year-old children. Meanwhile，fluoride concentration in drinking water was measured. Results For the 5 year-old children，the prevalence and DMF index had no statistical difference between the industrial areas and non-industrial areas. For the 12 year-old children，the prevalence，SiC index and DMF index showed markedly higher in industrial areas than in non-industrial areas. Still more，the dental fluorosis index was near the epidemic.The oral plaque index demonstrated lower in the industrial areas than that in non-industrial areas.The fluoride concentration in drinking water was under the national criterion in both areas(1.0 mg/L). Conclusion Some environmental factors in nonferrous metal industry areas may contribute to dental caries in children.
