国内外大量的流行病学资料已经证实,通过限制水氟浓度来防止斑釉齿的发生,并维持一定的水氟浓度来预防龋齿,是一个极其有效的公共卫生措施。各国的水质标准都规定了氟的标准,所定浓度基本一致,但也略有差别。多数订为1.0mg/1或1.5mg/1(如世界卫生组织、美国、苏联、南斯拉夫、法国、墨西哥等), A large number of epidemiological data at home and abroad have confirmed that it is an extremely effective public health measure to prevent the occurrence of spot glaze teeth by limiting the water fluoride concentration and to maintain a certain water fluoride concentration to prevent dental caries. The water quality standards of all countries have stipulated the standard of fluorine, the concentration is basically the same, but also a little difference. Most are set at 1.0mg / 1 or 1.5mg / 1 (such as WHO, the United States, the Soviet Union, Yugoslavia, France, Mexico, etc.)
