摘　　要：目的探讨不同水氟含量与儿童氟斑牙和龋齿患病关系.方法2014-2019年,选择陕西省渭南市的大荔县和合阳县、咸阳市的礼泉县、榆林市的府谷县、宝鸡市的陈仓区、西安市的阎良区共计5个市的6个县(区)作为调查点,选择不同水氟含量的村作为调查村.每个调查村采集3份末梢水,检测水氟含量.对调查村所有在校8~12周岁儿童进行氟斑牙和龋齿检查,同时采集儿童即时尿样,检测尿氟含量.结果共检测水样48份,水氟含量范围为0.23~3.70 mg/L;调查8~12周岁儿童1021名,检出氟斑牙患者372例,检出率为36.43%;检出龋齿患者198例,检出率为19.39%;检测儿童尿样868份,尿氟均值为1.47 mg/L.二次拟合曲线和相关关系方程显示,儿童龋齿检出率随着水氟的升高呈先降低后升高的趋势(F=14.470,P<0.05),水氟在1.2~<2.0 mg/L时龋齿检出率最低.儿童氟斑牙检出率随着水氟的升高而升高(F=52.215,P<0.05),水氟为1.0~<1.2 mg/L时,儿童氟斑牙检出率为31.90%(37/116),基本达到国家控制线(30%).结论水氟在1.0~<1.2 mg/L时,既能降低龋齿检出率,又能控制氟斑牙的流行.Objective To investigate the relationship between different fluorine concentrations in drinking water and dental fluorosis and caries of children.Methods In 2014-2019,5 cities and 6 counties(districts)were selected,which were Dali and Heyang counties of Weinan City,Liquan County of Xianyang City,Fugu County of Yulin City,Chencang District of Baoji City,and Yanliang District of Xi'an City,villages of different water fluorine contents were selected,3 tap water samples were collected from each village to detect the water fluoride content.The prevalence of dental fluorosis and caries in children aged 8 to 12 years old in villages was investigated,and children's urinary fluorine level was determined.Results Totally 48 water samples and 868 urine samples were tested,and the water fluorine content was from 0.23 to 3.70 mg/L,and the urinary fluorine mean was 1.47 mg/L;1021 children aged 8-12 years old were examined,372 were diagnosed with dental fluorosis,the detection rate was 36.43%;198 with caries,the detection rate was 19.39%.The detection rate of caries in children decreased and then increased with the increase of water fluorine(F=14.470,P<0.05),and the detection rate of caries was the lowest when the water fluorine was 1.2-<2.0 mg/L.The detection rate of dental fluorosis in children increased with the increase of water fluorine(F=52.215,P<0.05),when the water fluoride was 1.0-<1.2 mg/L,the detection rate of children's dental fluorosis was 31.90%(37/116),which was basically within the national control line(30%).Conclusion The content of water fluoride in 1.0-<1.2 mg/L,can not only reduce the detection rate of caries,but also control the prevalence of dental fluorosis.
