荧光分析法研究偶联剂与牙体组织的联结机理

A study of mechanism of coupling agent bonding to tooth tissues with fluorometric analysis

为了进一步探讨牙体组织与粘接剂的粘接机理,我们研制了具有荧光的粘接偶联剂(CGE(N)-1,用固体荧光分析方法对CGE(N)-1,牙体组织,及CGE(N)-1丙酮溶液处理后的牙体组织进行了分析测试．结果表明:用偶联剂处理后的牙面其荧光光谱与未处理的相比发生了明显的红移;说明偶联剂同牙体组织之间发生了化学结合．溶液中的测试结果也证明了上述结论．

In order to study the mechanism of coupling agent bonding to hard tooth tissues, a fluorescent coupling agent-CGE(N)-1, hard tooth tissues, hard tissues treated with the solution of CGE(N)-1 have been measured. The results indicate that the fluorescence spectra of treated hard tissues is red-sift, i.e. the chemical bonding occurs between tooth tissues and coupling agent. The measured result of solution supports the conclusion.
