引言 10岁内摄入含氟量约为1 PPm或以上的水可使恒牙发生牙釉氟中毒。因此,只有在恒牙萌出前,牙组织仍在发育时吸收氟,才会发生斑釉。斑釉的程度不等,由表层完整、硬且有光泽的不透明白色小斑至牙面具有明显暗棕色的釉质呈麻点状的损害。氟中毒牙釉的特征是,在重度时,与明显的当矿化性表面缺损一样,釉质疏松性增加。牙氟 Introduction 10 years of age intake of fluoride is about 1 PPM or more water can cause permanent teeth tooth enamel fluorosis. Therefore, only in the eruption of permanent teeth, tooth tissue is still developing absorption of fluorine, spot glaze occurs. The extent of the spot glaze, from the surface integrity, hard and shiny opaque white small spots to the tooth surface has obvious dark brown enamel pitting damage. Fluoride poisoning enamel is characterized by an increase in enamel bulkiness, at the same time as severe mineralized surface defects. Tooth fluoride
