摘要：In Korea,fluoride was first introduced into the drinking water of residents of Jinhae. KyungNam in 1981 for the prevention of dental caries. Ever since,growing numbers of communities favor fluoridation. The mechanism of F prevention of tooth decay is well knomwn: fluoride ions suhstitute for hydroxyl ions in hydroxyapatite of hard tissues,which result in crystal perfection,with consequent reduction in dental caries. Soluble fluorides such as sodium fluoride are almost completely absorbed from the gastrointestinal tract. Hnwever,the presence of dlivalent or trivalent cations such as aluminum,magnesium. and calcium that can complex with F can reduce the degree of absorption. In U.S.A. over 70H0 communities are nuw adding F to their drinking water. However. some portion of population oppuse fluoridation. vwoicing hoth concern about the safety of fluoridation as well as for personall choice. Thus. This paper reviews the interaction of fluoride and cation;as well asfluoride and supxests jxissible problems associated with fluoridation. a controwersial issue.
