通过在我国河北农村四个氟暴露水平不同地区，调查７－１５岁人群的总摄氟量和氟牙症患病情况，提出了在应用氟防龋工作中，除考虑饮水含氟量外，还应考虑到空气、食品等总摄氟量的问题。本次调查结果显示：７－１５岁儿童每日总摄氟量为１．５１ｍｇ时，没有出现氟牙症的流行。统计分析结果表明：儿童适宜总摄氟量为１．６０ｍｇ／日，不会出现氟牙症流行；安全总摄氟量为２．１ｍｇ／日，为正常与氟牙症流行之间的边缘，是可允许的范围。
Through surveying the total fluorine exposure and the prevalence of dental fluorosis among four fluoride exposure levels in Hebei rural areas in China, it is proposed that in addition to fluorine content in drinking water, Should also take into account the air, food, etc. total fluorine content of the issue. The survey results show that: children aged 7-15 total daily fluoride intake of 1.51mg, there is no epidemic of dental fluorosis. The results of statistical analysis showed that the suitable amount of fluorine for children was 1.60mg / day, the prevalence of dental fluorosis would not appear, the safety of total fluoride intake was 2.1mg / day, which was the edge between normal and dental fluorosis, Is the allowable range.
