一、引言对饮用水中氟浓度与龋病发病率的众所确认的反比关系进行广泛研究,目的是决定最适宜的氟摄入量,从而获得氟素的最大防护作用和产生最小的不利影响。本文复习了现有的有关氟素的摄入、代谢与斑釉发生关系的知识。二、氟化物的地球化学氟是所有化学元素中负电性最强的元素。在自然界中极少有或从未发现单独存在的氟元素。而绝大多数是以氟化物的形式存
I. INTRODUCTION Extensive research has been conducted on the well-established inverse relationship between the fluorine concentration in drinking water and the prevalence of dental caries in order to determine the most appropriate fluoride intake to maximize the protection of fluorocarbons and to produce the least adverse effects . This article reviews existing knowledge of the relationship between fluoride intake and metabolism and spot glaze. Second, fluoride geochemistry Fluorine is the most electronegative element of all chemical elements. There is little or no single element of fluorine in nature. The vast majority of fluoride in the form of deposit
