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1.0mg/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。
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 exaniined, 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）. Condusion Some environmental factors in nonferrous metal industry, areas may contribute to dental caries in children.
