甘肃省某工业区和农业区儿童龋病情况的调查和比较研究

A comparative study on children's dental caries between industrial and agricultural areas in Gansu, China

目的通过对甘肃省某有色金属工业区和临近农业区儿童龋患状况进行流行病学调查分析,了解当地儿童龋病的发病情况和分布特点,探讨儿童龋病发病的影响因素,同时为该地今后开展牙病防治工作提供依据。方法选择某工业区和临近农业区儿童作为研究对象,采用随机抽样的方法分别在两地抽取5岁和12岁儿童各200名共800人,调查内容包括龋病患病状况、口腔卫生状况和12岁组氟牙症状况,以及问卷调查。结果该工业区和农业区5岁组儿童龋病发病差异无统计学意义,工业区12岁组儿童龋病发病显著高于农业区同组水平,且氟牙症指数处于流行边缘;工业区5岁和12岁组儿童的菌斑指数显著低于农业区同组水平;工业区SiC指数高于农业区。结论该工业区儿童龋病发病的影响因素可能不单单是社会经济状况,当地环境工业污染也许是影响因素之一。

Objective To evaluate the prevalence of children＇s dental caries in some nonferrous metal industrial and agricultural areas in Gausu province and to provide a reference for the province＇s oral health planning. Methods Two hundreds of 5 - year - old children and 200 12 - year - old in nonferrous metal industrial area and in the neighboring agricultrial area were randomly sampled to examine and complete a questionnairy survey, respectively. The oral examination was included the condition of dental caries and oral hyginene for children of both ages, and dental fluoresis for 12 - year - old children. Results （1） The prevalence and DMF index of the 5 - year - old children of both the industrial and agricultural areas showed no difference.（2）The prevalence, SiC index and DMF index of 12 year - old children in the industrial area showed markedly higher than that of the agricultural area, and the fluoresis index was on the edge of prevalence. （3）The oral plaque index of all the children in the industrial area was lower than that of the agricultural area. Conclusion The factors influencing children＇s dental caries in this nonferrous metal industrial estate may be related with the social status, economical condition and the environment pollution.
