Abstract
Aim: The aim of this study is to evaluate and compare the apical sealing ability of new bioceramic-based (TotalFill BC) and methacrylate-based (Hybrid Root SEAL) sealers with epoxy resin-based (AH Plus) sealer using a dye penetration method. Materials and Methods: A total of 74 extracted mandibular premolars were selected and decoronated to the root length of 14 mm. The root canals were prepared using high flex to size 35, 0.06 taper to the working length. After completion of the biomechanical preparation of root canal, samples were divided into four experimental groups (n = 16) and two control groups (n = 5). Experimental groups were obturated as follows - Group A: Obturated with AH Plus + 6% conventional gutta-percha, Group B: Obturated with TotalFill BC + 6% conventional gutta-percha, Group C: Obturated with TotalFill BC + 6% bioceramic gutta-percha, and Group D: Obturated with Hybrid Root SEAL + 6% conventional gutta-percha. Results: The best results were obtained with TotalFill BC with bioceramic gutta-percha followed by TotalFill BC with conventional gutta-percha, AH Plus, and Hybrid Root SEAL. Conclusion: Bioceramic sealer with bioceramic gutta-percha or conventional gutta-percha provides comparable sealing ability to AH Plus and superior to Hybrid Root SEAL.
