Scanning electron microscopy observations of surface morphology of initial artificial enamel lesion treated with lanthanum milk and fluoride milk and calcium milk 镧奶、氟奶、钙奶处理早期人工龋后表面结构的扫描电镜观察
The composition, morphology and structure of the lanthanum fluoride were analyzed by means of TG-DTA analysis, SEM and XRD. 通过差热分析、扫描电镜、X射线衍射等手段对产品的组成、形貌、结构等进行了研究。
Results The milk with lanthanum, fluoride or calcium has the ability to promote remineralization of enamel caries when compared with the control. 结果与对照组相比,所有矿化液均有促进再矿化的作用,镧奶组釉质表面有规则、疏松的矿物沉积并结晶化。氟奶组有明显的规则均匀的矿物沉积。
