Abstract

Purpose: The purpose of this study was to investigate the reaction products formed by application of three tooth etchants to hydroxyapatite.

Methods: Tooth etchants with three different compositions, designed for application to teeth before dental adhesive - " K-etchant GEL" (containing phosphoric acid), "Enamel Conditioner" (containing organic acids), and "Multi Etchant" (containing acidic monomer) - were applied to hydroxyapatite plates.

Results: Atomic force microscopy measurements revealed that Multi Etchant formed nano-sized particles on the hydroxyapatite. X-ray diffraction and Fourier transform infrared spectrometer analyses of the powdered hydroxyapatite indicated that Enamel Conditioner produced calcium tartrate whereas K-etchant GEL generated monetite. These results indicated that each etchant reacted with hydroxyapatite in a different way.

Conclusion: Not only differences among the etching ability of etchants, but also differences in the reaction compounds they produce may influence bonding performance in clinical practice.

不同成分牙齿腐蚀剂对羟基磷灰石的反应产物分析。

目的:研究三种牙蚀剂与羟基磷灰石的反应产物。方法:将三种不同成分的牙蚀刻剂(K-etchant GEL，含磷酸)、牙釉质调节剂(釉质调节剂，含有机酸)和Multi Etchant，含酸性单体)应用于羟基磷灰石板。结果:原子力显微镜测量显示，Multi蚀刻剂在羟基磷灰石表面形成纳米级颗粒。粉末羟基磷灰石的x射线衍射和傅里叶变换红外光谱仪分析表明，珐琅质调节剂产生酒石酸钙，而k -蚀刻剂凝胶产生钱铁矿。这些结果表明，每种蚀刻剂与羟基磷灰石的反应方式不同。结论:在临床应用中，不仅蚀刻剂的蚀刻能力存在差异，而且所产生的反应化合物的差异也会影响粘接性能。
