广州市在开展自来水加氟预防龋齿18年后,于1983年9月26日起停止自来水加氟。对今后开展龋齿防治综合措施和研究成为当前的重要对策,本文提出如下的意向,供参考。一、自来水加氟18年的回顾众所周知,龋齿是一种危害人们健康最常见的口腔疾病。1980年岳松龄氏报道,先后调查了除台湾省外69个地区共4,562,779人,平均患龋率37.3%,龋均(患龋者平均龋齿数)2.47。郭嫒珠氏1982年报告为57.9%,解婷氏报告约在50%。由此可见,龋病严重危害我国人民的健康。广州市龋病通过1960～1966年调查,发现广州市中小学生龋病率为63.82%(表1)。因此,口腔卫生专家认为,广州市饮用水含氟量较低(0.2～0.3mg/l),中小学生的龋病率高。于是,参照外国有些国家饮用水加氟的办法,提出广州市自来水加氟建议。1965年6月先在芳村区作为试点加氟,并于1965年11月中旬在全市各自来水厂投加氟硅酸。拟定观察18年为期。加氟标准是夏季为 Guangzhou municipal water fluoride in the prevention and treatment of dental caries 18 years later, in September 26, 1983 to stop tap water fluoride. To carry out the comprehensive prevention and treatment of dental caries in the future and measures to become the current important countermeasures, the paper proposed the following for your reference. First, tap water fluoride 18 years of retrospective As we all know, dental caries is one of the most common oral diseases endanger people’s health. In 1980, Yue Songling reported that it investigated 4,562,779 people in 69 districts outside Taiwan, with an average caries prevalence rate of 37.3% and an average of 2.47 caries per caries. Guo Xiang Zhu’s report in 1982 was 57.9%, Xie Ting’s report was about 50%. This shows that dental caries seriously endanger the health of our people. Guangzhou caries passed the survey from 1960 to 1966 and found that caries prevalence in primary and secondary school students in Guangzhou was 63.82% (Table 1). Therefore, oral health experts believe that drinking water in Guangzhou City, low fluoride (0.2 ~ 0.3mg / l), caries prevalence of high school students. Therefore, with reference to some countries in foreign countries fluoride approach to drinking water, put forward fluoride water fluoride advice in Guangzhou. In 1965 June Fangcun District as a pilot fluoride, and in mid-November 1965 in the city’s water plant put fluorosilicate. It is planned to observe the 18-year period. Fluoride standard is summer
