摘　　要：2 0只 6月龄当地山羊在工业氟重污染区放牧 12个月 ,旨在研究在缺乏营养情况下 ,氟对牙基质发育的影响。取严重氟变的第一切齿 ,脱钙后作组织病理学检查。结果表明 ,对照组健康羊牙齿基质的釉质部分结构致密 ,本质部分呈现良好的网状结构 ,而严重氟中毒牙齿的釉质部分致密性较差 ,有的出现严重的孔洞性损伤 ,从釉质外表面通过釉质进入本质区 ,牙本质的网状结构明显断裂损伤。Twenty native goats,6 months old,were pastured for 12 months in Baotou area severely polluted by industrial fluoride to study the effect of fluoride on the tooth matrix under condition of malnutrition.The first pairs of incisors,highly fluorosed teeth,were decalcified for histopathological examination.The results showed the matrix of the incisors was severely damaged.Compared with normal matrix in which enamel part was dense,and dentin part presented good net structure,matrix of fluorosed incisors appeared damaged hole from enamel outer through enamel into detine,and destine structure was obviously destroyed.
