Aim: This study assessed the shear bond strength of a nanohybrid composite resin and a compomer to Biodentine® using three bonding systems (total-etch one-bottle, one and two- step self-etch).
Material and Methods: A total of ninety customized acrylic blocks were prepared and 4-mm diameter × 2-mm deep holes were instrumented in all blocks. The holes were filled with Biodentine®. Dividing the blocks into 6 groups, Groups 1–3 had compomer placed over the Biodentine® with Clearfil SE Bond®, Prime&Bond NT® universal testing machine, or Clearfil Universal Bond®, respectively; Groups 4–6 were restored with composite using the same adhesives. A universal testing device determined the shear bond strength, and the fractures were examined with a stereomicroscope. Obtained data were analyzed with a two-way ANOVA and Tukey post-hoc tests.
Results: The composite’s mean shear bond strength to Biodentine® was significantly higher (p <0.05) than the compomer’s. The bond strength was found to be higher in using with the two-step self-etch adhesive system for both restorative materials (p <0.05). The highest bond (14.10 ± 2.83 MPa) was achieved in Group 4, while Group 2 was the lowest (8.25 ± 0.97 MPa).
Conclusion: The bonding to Biodentine® was affected by both the restorative material and adhesive system. Composite resins applied with the different adhesive systems had higher shear bond strengths than did compomer with the same adhesives. Additionally, the two-step self-etching adhesive system was more likely to obtain high shear bond strength irrespective of the restorative material (compomer or composite).
