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。
OBJECTIVE: To evaluate the clinical effect of casein phosphopeptide-peptide complex on the remineralization of enamel enamel adjacent to the surface. Methods: A total of 30 canines with decreasing number of orthodontics were enrolled in this study. The specimens were enamel-removed with glaze and polished with 35% phosphoric acid. They were randomly divided into A, B and C3 groups. A group was treated with casein phosphopeptide- Body, group B fluoride protective paint, group C untreated as a control group, after PH circulation in vitro 20d using quantitative microhardness test. Results: There was significant difference in the microhardness between every two groups. (P values were less than 0.05), the highest in group A and the lowest in group C CONCLUSION: Casein phosphopeptide-calcium-phosphate complex has good remineralization on enamel adjacent to enamel.
