The aim of this study is to investigate the efficiency of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) gel and resin infiltrant on decalcified enamel, and to explain the correlation, if any, between ion release capacities and shear bond strength (SBS). A total of 80 premolar teeth were used (n=20). Group I was the control, while a demineralization protocol was performed for other groups. CPP-ACP gel and resin infiltrant, respectively, was applied to Groups III and IV. Pre and post-demineralization energy dispersive X-Ray analysis of all groups and post-application of Groups III and IV were undertaken. SBS tests were performed. Ca/P ratio significantly increased after the applications. Both agent groups showed a significant decrease in SBS values compared to others. There was no correlation between SBS and Ca/P ratio changes. It can be said that CPP-ACP and resin infiltrant therapies enhance the tooth mineral content, but show lesser SBS values than the control and demineralization only groups.
本研究旨在探究酪蛋白磷酸肽-无定形磷酸钙（CPP-ACP）凝胶和树脂渗透剂对脱矿釉质的效果，并解释离子释放能力与剪切粘结强度（SBS）之间是否存在相关性。共使用 80 颗前磨牙（n=20）。第 I 组为对照组，对其他组进行脱矿处理。第 III 组和第 IV 组分别应用 CPP-ACP 凝胶和树脂渗透剂。对所有组进行脱矿前后的能量色散 X 射线分析，并对第 III 组和第 IV 组进行应用后分析。进行 SBS 测试。应用后 Ca/P 比值显著增加。与其他组相比，两种试剂组的 SBS 值均显著降低。SBS 值与 Ca/P 比值变化之间无相关性。可以说 CPP-ACP 和树脂渗透剂疗法可以增强牙齿的矿物质含量，但与对照组和仅脱矿组相比，SBS 值较低。
