斑釉是表现在牙齿上的慢性氟中毒最敏感的指标。此病多发生在前牙和双尖牙牙冠之唇面。轻型表现为白垩色或淡黄色,表面光滑无光泽。重型牙釉质表面多不光滑,出现沟纹,凹坑不平,易磨损碎裂,破坏牙冠外形,造成严重功能障碍,并影响美观。因此很值得研究。氟斑牙的病理组织学方面研究得少。文献报道,Black和Mckay(1961),Williams(1923),Ainswarth(1933)等氏限于光镜和肉服的描述,Parling和Brook(1959),Gusta-
Spot glaze is the most sensitive indicator of chronic fluorosis on the teeth. The disease occurred in the anterior teeth and the bicuspid crown lip. Light performance is chalk or light yellow, the surface is smooth and dull. Heavy-duty enamel surface and more non-smooth, there groove, pit uneven, easy to wear fragmentation, destruction of crown shape, causing serious dysfunction, and affect the appearance. So it is worth studying. There is little research on the histopathology of dental fluorosis. It has been reported in the literature that Black and Mckay (1961), Williams (1923) and Ainswarth (1933) are limited to the description of light microscopy and meatwear.
