Objectives: The obturation quality of MTA, Biodentine, and single cone obturation with Endosequence BC Sealer HiFlow in teeth with simulated internal root resorption (IRR) was evaluated by using cone beam computed tomography. Materials and Methods: Standardized IRR cavities were created using 30 extracted mandibular premolar teeth and randomly assigned into 3 groups (n = 10). IRR cavities were filled with MTA, Biodentine, single cone + Endosequence BC Sealer HiFlow. Percentage of voids between resorptive cavity walls and obturation material (external void), and inside the filling materials (internal voids) were measured. Results: Single cone + Endosequence BC Sealer HiFlow presented significantly lowest values of external and internal voids (p < 0.05),then Biodentine showed a significantly lower external voids (p < 0.05),MTA presented the most Voids both internal as Well as external. Conclusion: None of the filling materials created void-free obturation in resorption cavities. Single cone + Endosequence BC Sealer HiFlow and Biodentine may favor its application in teeth with IRR over Angelus MTA.
