Description: A root canal obturated with a calcium silicate–based sealer (bioceramic sealer [BCS]) and a modified gutta-percha cone (bioceramic cone [BCC]) might improve the fracture resistance of the root. The objective of this study was to evaluate root reinforcement of a bioceramic cone/sealer (TotalFill; FKG Dentaire SA, La Chaux-de-Fonds, Switzerland) by investigating the fracture resistance, push-out bond strength, sealer penetration, and modulus of elasticity (MOE) in comparison with gutta-percha/AH Plus (Dentsply Maillefer, Tulsa, OK) (GP/AH).

At the conclusion, participants should be able to:

Determine the fracture resistance, push-out bond strength, and sealer penetration of roots obturated with BCC/BCS; 
Compare BCC/BCS obturated root canals with root canals obturated with GP/AH;
Describe the modulus of elasticity (MOE) of BCC, GP, BCS, and AH was evaluated.
