The aim of this study was to evaluate the shear bond strength of the AH Plus, Tubli-Seal, MTA Fillapex, and Sealapex root canal sealers when used with WMTA (White Mineral Trioxide Aggregate) and Biodentine. WMTA and Biodentine were prepared and placed into central holes of cylindrical acrylic blocks. The blocks were stored at 37°C and 100% humidity for 96 hours for the cements to set. The samples were then divided into 4 subgroups of 10 blocks each to be tested with the four root canal sealers, Sealapex, AH Plus, MTA Fillapex, and Tubli-Seal. The sealers in cylindrical plastic tubes were placed in the center of the WMTA and Biodentine surface. After the setting process, the samples were stored at 37°C and 100% humidity for 48 hours The chisel edge of a stainless steel plunger was inserted into the cement/sealer interface to measure the shear bond strength (SBS) and the data were statistically evaluated by One-way analysis and post hoc Turkey tests (p<0.05). The highest and lowest bond strength values were recorded for AH Plus and Tubli-Seal to Biodentine, respectively. Tubli-Seal and MTA Fillapex demonstrated similar SBS values. Sealapex showed significantly higher bond strength than Tubli-Seal and MTA Fillapex. No significant differences were found between WMTA and Biodentine in all root canal sealer groups. MTA and Biodentine demonstrated similar shear bond scores with all root canal sealers. AH Plus had the highest bonding values to MTA and Biodentine when compared with the other sealers
