70多年前Head(1912年)首先发现人工酸蚀的牙釉质浸泡在唾液中可发生再矿化,继后,很多临床和实验室研究都进一步证实了早期自然龋和人工龋样损害在体内唾液中或体外合成矿化液中均可发生再矿化现象。关于初期釉质龋表面结构的扫描电镜观察和描述已有很多报导,但有关再矿化釉质表面的形态学研究国内报导较少,本文用扫描电镜观察人工釉质龋再矿化前后的表面结构改变以进一步认识矿化物质在釉质表面沉积行为的规律,这对深入探讨再矿化机制具有一定的意义。很多体外研究报告了氟化物能增
More than 70 years ago Head (1912) first discovered artificial acid-etching enamel soaked in saliva can occur remineralization, followed by many clinical and laboratory studies have further confirmed the early natural caries and artificial caries-like damage in vivo saliva Mineralization in vitro or in vitro mineralization can occur in the phenomenon of remineralization. However, there are few reports on morphology of remineralized enamel surface in our country. Scanning electron microscopy was used to observe the surface structure changes before and after enamel carious remineralization Further understanding of the law of the depositional behavior of mineralized materials on the surface of the enamel is of great significance for further exploration of the remineralization mechanism. Many in vitro studies have reported that fluoride can increase
