【摘要】目的:比较三种生物活性牙膏 (精氨酸专效抗敏牙膏、GC护牙素、奥敏
清脱敏糊剂)对牙釉质再矿化脱矿作用的影响.方法:建立釉 质早期龋坏模型,经过
15 d pH循环及耐酸性试验后,测定牙釉质在不同时间点的表面硬度(SM H)值,并
进行统计学分析.结果:经pH循环后,三组牙膏处理组牙釉质的SMH值均显著高
于对照组(P＜0.001),耐酸性实验后,各组的SMH值显著下降(P＜0.05),牙膏处
理组 牙釉质的SMH值下降较少.pH循环及耐酸性实验后,精氨酸组和奥敏清组
的SMH值均比GC护牙素 组高(P＜0.05),精氨酸组和奥敏清组相比较,差异无统
计学意义.结论:三种牙膏都可促进脱矿 牙釉质再矿化,抑制酸性环境下的脱矿.精
氨酸专效抗敏牙膏和奥敏清脱敏糊剂较GC护牙素有更好的再 矿化潜能,减少釉
