酪蛋白磷酸肽钙磷复合体对邻面去釉牙釉质再矿化的研究

目的:评价酪蛋白磷酸肽钙磷复合体对邻面去釉牙釉质再矿化的临床效果。方法:以正畸减数的双尖牙为实验样本30个,采用去釉砂条去釉和35%的磷酸抛光,随机分成A、B、C3组,A组应用酪蛋白磷酸肽钙磷复合体,B组应用氟保护漆,C组未处理为对照组,经体外PH循环20d后采用定量的显微硬度检测。结果:每2组的显微硬度值差异均有统计学意义。(P值分别小于0.05)其中A组最高;C组最低。结论:酪蛋白磷酸肽钙磷复合体对邻面去釉牙釉质具有很好的再矿化作用。

Study of Enamel Remineralization with Casein Phosphopeptide-amorphic Calcium Phosphate in Interproximal Enamel Reduction

Objective:To evaluate remineralization effect of casein phosphopeptide-Amorphic calcium phosphate in interproximal enamel redution.Methods:Thirty premolars from orthodontic extraction were included.the interproximal enamel reduction was done with stripping disk and polished with 35% orthophosphoric acid.The teeth were divided evenly into A.Band C group randomly.A group teeth were remineralizated with casein phosphopeptide-Amorphic calcium phosphate.B group teeth were remineralizated with fluor protector.C group teeth were served as control group.ALL the samples were treated with PH cycle in vitro for 20 days.the interproximal enamel reduction surface was detected by microhardness testing machine.Results:there were highly significant differences between A and B,A and C,B and C.The mean microhardness in A group was signifocantly greater than that in Cgroup.Conclusion:Casein phosphopeptide-Amorphic calcium phosphate had good remineralization after interproximal enamel reduction.
