摘　　要：本文应用Ｘ射线能谱分析仪对正常牙和氟斑牙釉质表面进行了无机成分测定。结果发现，氟斑牙表面的微量元素Ｆｅ（铁）、Ｍｎ（锰）、Ｚｎ（锌）的含量比正常牙釉质高，而Ｃａ（钙）的含量稍低于正常牙釉质表面。作者认为，氟斑牙的抗龋能力可能与釉质表面微量元素的含量有关。Inorganic elements were determined on the surface of dental fluorosis and normal teeth by using X -ray energy spectrometry. The results showed that contents of Fe,Mn,Zn,in dental but the content of Ca was slightly lower. The author considered that anticarious ability of dental fluorosis may be related to the contents of microelements on the surface of enamel.
