甘肃省某有色金属工业区及非工业区儿童患龋状况比较
甘肃省某有色金属工业区及非工业区儿童患龋状况比较【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。

Comparative Study on Dental Caries Status of Children Living in Nonferrous Metal Industrial and Non-Industrial Areas/ZHANG Jing?*,ZHAO Wang-hong,WANG Zhen-quan,et al. ?* School of Stomatology,Lanzhou University,Lanzhou(730000),China
【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.
