The tensile strength of the bond formed between etched bovine enamel and selected resin systems was evaluated; also, the need for a resin pulpal barrier was examined. Results indicate that the BIS-GMA unfilled primer is unnecessary for strength or as a pulpal protectant. The large scatter of results substantiates the clinical hypothesis that the effectiveness of the acid etch is highly variable.
评估了酸蚀牛牙釉质与选定树脂系统之间形成的粘结抗拉强度；同时，研究了对树脂牙髓屏障的需求。结果表明，双酚A-甲基丙烯酸缩水甘油酯（BIS-GMA）未填充底漆对于强度或作为牙髓保护剂而言并非必要。结果的较大离散度证实了临床假设，即酸蚀的有效性具有高度可变性。
