摘要/Abstract

摘要： 目的：探讨酪蛋白磷酸多肽-无定形磷酸钙(casein phosphopeptide-amorphous calcium phosphate，CPP-ACP) 与不同浓度氟离子联合应用对脱矿釉质再矿化的作用。方法：取正畸拔除的健康前磨牙30颗，乳酸凝胶法制备人工早期釉质脱矿后, 随机分为对照组(5% CPP-ACP组)、实验组1(5% CPP-ACP+500 mg/L F-组)和实验组2(5% CPP-ACP+900 mg/L F-组)，采用MH-5型显微硬度仪测量处理前、后釉质标本的显微硬度，采用SPSS 18.0软件包对数据进行统计学分析。结果：显微硬度测量显示，实验组2牙釉质的表面显微硬度变化显著高于实验组1(P<0.05)及对照组(P<0.01)。结论：CPP-ACP能够促进脱矿釉质再矿化，氟对其有加强协同作用。在一定范围内，氟浓度越高，协同作用越好。

Abstract: PURPOSE: To evaluate the effect of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) combined with different concentrations of fluoride on demineralization of enamel remineralization. METHODS: Extracted premolar teeth for orthodontic reason were immersed into lactic acid gel to prepare artificial white spot lesions. Then the specimens were randomly assigned to 3 groups: 5% CPP-ACP group as control, 5% CPP-ACP +500 mg/L F- group and 5% CPP-ACP +900 mg/L F- group, which were measured by micro-hardness tester. SPSS 18.0 software package was used for data analysis. RESULTS: There were significant differences in micro-hardness between control group and experimental group 1 and experimental group 2 by SNK-q test (P<0.05). CONCLUSIONS: CPP-ACP can make the demineralization of enamel remineralization occurs. F can promote the CPP-ACP remineralization. The increase of fluoride can make the CPP-ACP remineralization better below 1000-1500 mg/L.
