我国目前乳牙龋齿非常盛行,一般在80％以上,多的在90％以上,而且治疗率很低,正在影响儿童的生长发育和身心健康,所以乳牙龋齿的预防有它特别的意义。在幼儿,能最快地观察到自来水加氟降低龋率的全部效果,同样能最快地观察到停止自来水加氟升高龋率的全部后果。广州市芳村地区1965年开始自来水加氟,我们在1972年和1980年报告了防龋效果。1982年起加氟被部分停止,1983年被全部停止,因而我们继续观察了停止加氟对龋率的影响。
At present, deciduous tooth decay in our country is very prevalent, usually above 80%, more than 90%, and the treatment rate is very low, affecting the growth and development of children and their physical and mental health. Therefore, the prevention of deciduous deciduous teeth has its special significance. In young children, the fastest effect of tap water and fluoridation on caries reduction can be observed. All the same can be observed as soon as possible. Guangzhou Fangcun area began to tap water fluoride in 1965, we reported the anti-caries effect in 1972 and 1980. Fluoride was partially stopped in 1982 and totally stopped in 1983, so we continued to observe the impact of stopping fluoride on dental caries.
