Shear bond strengths of different adhesive systems to white mineral trioxide aggregate.
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.
