本世纪30～40年代国外确定水氟是引起人类斑釉的主要因素,并且认为它的适宜浓度是1毫克/升左右以后,创立了在低氟区实行加氟预防龋齿和在高氟区实行脱氟预防地方性氟中毒的两个保健措施。长期以来,我国许多研究者也在寻找水氟适宜浓度,一些报告发现在1毫克/升左右,一些报告认为1毫克/升左右已有斑釉进行,或者某些地区食物氟会明显干扰水氟适宜浓度的确定。1978—1980年我们在广东省农村一个天然氟区进行了流行病学调查。
This century, 30 to 40 years to determine the foreign water fluoride is the main cause of human spot glaze, and that its appropriate concentration is about 1 mg / l after the creation of fluoride in the implementation of low fluoride areas to prevent tooth decay and the implementation of high fluoride area Defluoride prevention of endemic fluorosis two defensive measures. For some time now, many researchers in our country are also looking for suitable water fluoride concentrations. Some reports find that at 1 mg / l, some report that 1 mg / l has been spotted glaze, or food fluoride in some areas may significantly interfere with water fluoride Determination of appropriate concentration. From 1978 to 1980, we conducted an epidemiological survey in a natural fluorine area of rural Guangdong.
