This study was conducted to compare the shear bond strengths of different adhesive systems to White Mineral Trioxide Aggregate (WMTA). To this end, 40 cylindrical acrylic blocks with a hole in the middle measuring 4 mm diameter x 2 mm height were prepared. The hole was filled with WMTA, and the specimens were allocated into four groups: Group 1--Prime & Bond NT; Group 2--AdheSE; Group 3--Xeno III; and Group 4--Adper Prompt L-Pop. In each group, a different adhesive system and a compomer (Dyract AP) were applied over WMTA. Shear bond strengths were measured using a universal testing machine, and then the data were subjected to one-way ANOVA and Scheffé's post hoc test (p<0.05). Significantly lowest shear bond strength value was obtained with Adper Prompt L-Pop, whereas Prime & Bond NT revealed higher shear bond strength than the others (p<0.05). In conclusion, an etch-and-rinse adhesive system--which exhibited significantly higher shear bond strength than self-etch adhesive systems--could be a preferred choice when placing compomer materials upon WMTA.
本研究旨在比较不同粘结系统与白色三氧化矿物凝聚体（WMTA）之间的剪切粘结强度。为此，制备了40个中间有孔的圆柱形丙烯酸块，孔的尺寸为直径4 mm×高2 mm。孔中填充WMTA，将试件分为四组：第1组——Prime & Bond NT；第2组——AdheSE；第3组——Xeno III；第4组——Adper Prompt L-Pop。每组在WMTA上应用不同的粘结系统和一种复合体（Dyract AP）。使用万能试验机测量剪切粘结强度，然后对数据进行单因素方差分析和谢费尔事后检验（p<0.05）。Adper Prompt L-Pop获得的剪切粘结强度值显著最低，而Prime & Bond NT的剪切粘结强度高于其他组（p<0.05）。总之，当在WMTA上放置复合体材料时，一种酸蚀冲洗粘结系统——其剪切粘结强度显著高于自酸蚀粘结系统——可能是首选。
