Preparation and Pre-Clincal Evaluation of Novel Polymeric Dental Adhesives with Excellent Safty

为了。改善牙科树脂在牙齿上的粘附力。制备了聚合物粘合剂并评估了其在牙科领域的应用。合成了由对苯乙烯磺酸和聚甲基丙烯酸甲酯大分子单体（gMS）组成的水溶性接枝共聚物。即使用水充分清洗，用 gMS 处理的牙齿表面也显示出与聚甲基丙烯酸甲酯相似的极性。这一发现意味着gMS发生反应并覆盖在牙齿表面。这也通过处理表面的 X 射线光电子能谱分析得到证实。经gMS水溶液处理后的牙科树脂与牙釉质的拉伸粘合强度约为8MPa，高于相应的对苯乙烯磺酸酯和甲基丙烯酸甲酯的无规共聚物表面的拉伸粘合强度。

In order. to improved adhesion of dental resins onto teeth. polymeric adhesives were prepared and its application to the dental fields was evaluated. A water-soluble graft copolymers composed of p-styrene sulfonic acid and poly (methyl methacrylate) macromonomer (gMS) were synthesized. The teeth surface treated with gMS indicated similar polarity of poly (methyl methacrylate) even it was washed with water sufficiently. This finding means that the gMS reacted and covered on teeth surface. This is also confirmed by X-ray photoelectron spettroscopic analysis of the treated surface. The tensile bond strength of the dental resin to tooth enamel treated with the gMS aqueous solution was about 8MPa which is higher than the surface with the corresponding random copolymers of p-styrene bulfonate and mehtyl methac-rylate.
