Özet
Purpose: To evaluate the adhesion of AH26 and Epiphany sealers to gutta-percha/Resilon surfaces and dentin in the presence or absence of the smear layer. Methods: Dentin, gutta-percha, and Resilon surfaces were filled with different combinations of AH26 and RealSeal sealers in eight groups: Group 1-Smear (-) dentin, filled with dentin bonding agent and AH26 sealer; Group 2-Smear (+) dentin, AH26; Group 3-Smear (-) dentin, AH26; Group 4-Smear (-) dentin, RealSeal sealer. In the remaning groups, gutta-percha and Resilon pellets were used as experimental surfaces to test the sealer adhesion. The samples were attached to a universal testing machine and pulled at 1 mm/s to determine the tensile bond strengths. Results: Statistical analyses revealed that the smear free dentin filled with AH26 had a significantly higher bond strength than those of the other groups (p< 0.05). The presence of the smear layer and dentin bonding agent significantly reduced the adhesion of AH26 to dentin (p< 0.05). The bonding of AH26 to Resilon and gutta-percha was significantly better than those of the RealSeal sealer (p< 0.05). Conclusion: The tensile bond strength of AH26 sealer to gutta-percha/Resilon and dentin was superior to that of RealSeal sealer.
