Abstract: (277 Views)

Background: Composite resins are widely used in restorative dentistry, yet polymerization shrinkage remains a significant challenge. This study aimed to evaluate the microtensile bond strength of indirect composite restorations to deep dentin with two different adhesive systems, considering varying decoupling times.
Materials and Methods: This experimental study involved 72 extracted molar teeth divided into six groups. Groups 1, 2, and 3 used Optibond FL, while groups 4, 5, and 6 used SE Bond. In groups 1 and 4, the bonding agent was applied followed by decoupling with time (DWT) and a 1 mm thick flowable composite. Groups 2 and 5 had a 0.5 mm composite applied, allowed a 5-minute DWT, then added another 0.5 mm composite. Groups 3 and 6 involved bonding and curing with a 1 mm composite but no DWT. All samples were restored with ENA Temp Micerium, and composite blocks were cemented. Micro-tensile bond strength was measured by applying a 500 N force until beam failure. Data were analyzed using ANOVA and Tukey's test (α = 0.05).
Results: Both Optibond FL and SE Bond adhesives, in combination with DWT, significantly increased the micro-tensile bond strength. Application of DWT at both stages (post-bonding and after the 0.5 mm flowable composite) resulted in higher micro-tensile bond strength compared to the groups without DWT.
Conclusion: The use of DWT significantly enhances the micro-tensile bond strength, and the timing of decoupling does not significantly affect the bond strength. Additionally, no significant differences were observed between the two types of bonding systems used.
