对确定饮水中氟化物的最大安全含量应为多少有很大争论,因为普遍认为可引起人类牙齿损害的氟化物浓度仅略高于有时甚至低于通常被认为对减小龋齿是最适宜的氟化物浓度。而且业已证明,甚至在饮水氟化物含量为所推荐的约1mg/L 时,也引起了许多确诊的氟中毒病例。迄今为止,有关公用饮水系统中氟化物对牙齿影响的调查,在极大程度上都没有评 There is considerable controversy about what the maximum level of safety of fluoride in drinking water should be because there is a general perception that the concentration of fluoride that causes tooth damage in humans is only slightly above and sometimes below the level of fluoride most commonly considered to reduce dental caries Chemical concentration. It has also been shown that many diagnosed fluorosis cases have been reported even at the recommended fluoride level of about 1 mg / L. So far, there has been very little comment on the impact of fluoride on public drinking water systems in dentistry
