A study of the adhesive interface between 4-MET/MMA-TBB resin and hydroxyapatite or bovine enamel was reported. The present report is a continuation of that study. The possible chemical interaction between 4-methacryloxyethyl trimellitic acid (4-MET) and bovine or human dentin was examined by laser Raman spectroscopy. A 4-MET monomer solution was prepared by evaporating two thirds of the methyl methacrylate (MMA) in a commercial dentin adhesive. The solution was then applied to a dentin surface after treating the surface with an aqueous solution of 10% citric acid containing 3% ferric chloride. A salt formed on both bovine and human dentin surfaces. This salt was formed by the process we previously reported in which 4-MET formed a salt on the hydroxyapatite and bovine enamel. No evidence was observed of chemical reaction between 4-MET and any organic component in the dentin.
一篇关于4-甲基丙烯酰氧乙基偏苯三酸酐/甲基丙烯酸甲酯-三丁基硼树脂与羟基磷灰石或牛牙釉质之间粘结界面的研究报告已有报道。本报告是该研究的延续。通过激光拉曼光谱研究了4-甲基丙烯酰氧乙基偏苯三酸（4-MET）与牛或人牙本质之间可能的化学相互作用。通过蒸发市售牙本质粘结剂中三分之二的甲基丙烯酸甲酯（MMA）制备了4-MET单体溶液。在用含3%氯化铁的10%柠檬酸水溶液处理牙本质表面后，将该溶液应用于牙本质表面。在牛和人牙本质表面均形成了一种盐。这种盐是通过我们之前报道的过程形成的，即4-MET在羟基磷灰石和牛牙釉质上形成盐。未观察到4-MET与牙本质中任何有机成分发生化学反应的证据。
