Fluor Protector对饮料所致牙釉质脱矿的抑制作用

Observation on the Inhibiting Effect of Fluor Protector on the Demineralization of Bovine Enamel after Exposure to Some Beverages

目的 研究 Fluor Protector对饮料导致牙釉质脱矿的抑制作用。方法 将牛牙齿标本分成实验组和对照组 ,实验组在 Fluor Protector预处理釉质后用不同种类饮料处理 ,对照组不经 Fluor Protector处理而直接用饮料处理。饮料的处理为 5分钟 /次 ,10次 /天 ,处理 7天以后 ,分别用肉眼和扫描电镜观察牙釉质表面发生的改变。结果 肉眼观察发现无论是实验组还是对照组 ,有色饮料均能导致牙釉质表面颜色发生改变 ,均能使牙釉质脱矿 ,表现为釉质呈不同程度的白垩色改变。扫描电镜观察发现 ,对照组除去离子水外 ,牙釉质的超微结构均发生改变 ,表现为牙釉柱中心晶体、釉柱间隔有不同程度的溶解 ,而实验组则表现出较明显的抑制作用。结论

Objective To investigate the role of Fluor Protector in the demineralization of bovine enamel after exposure to some beverages. Methods Twenty-four bovine teeth were divided into experimental and control groups. The enamel specimens of the experimental group were pretreated with Fluor Protector and then exposed to beverages; the enamel specimens of the control group were exposed to beverages directly. All the enamel specimens were exposed to beverages 10 times a day and 5 minutes each time. After 7 days' exposure to the beverages, all the specimens were observed by scanning electron microscope (SEM). Results Different degrees of solubilization of enamel prisms in the control group were demonstrated by SEM. The solubilization of enamel prisms in the experimental group was much more slight than that in the control group. Conclusion Fluor Protector can inhibit the demineralization of enamel caused by beverages.
