这篇研究的目的是为了评估预粘接时间和材料对自粘结水门汀与侵蚀和完整釉质的剪切粘接强度(SBS)的影响。

这篇研究的目的是为了评估预粘接时间和材料对自粘结水门汀与侵蚀和完整釉质的剪切粘接强度(SBS)的影响。

研究将酸蚀过的釉质样本按照釉质表面处理条件的不同分为5组(n=20 each):组N, 侵蚀釉质(未进行表面预处理); 组PH15, 35% H3PO4酸蚀15 s; 组PH30, 35% H3PO4酸蚀30 s; 组L30, 20%乳酸酸蚀30 s和组L60, 20%乳酸酸蚀60 s。使用2种自粘结水门汀中的1种将复合树脂块粘接到釉质表面。结果表明,自粘结水门汀与腐蚀釉质表面的粘接强度在应用20%乳酸酸蚀30 s时显著增强。
