Abstract
Background: Endodontic failure can be caused by the teeth's lack of strength after endodontic treatment, which leads to post-endodontic vertical root fracture. The intra-orifice barrier is a trustworthy reinforcement method for endodontically treated teeth as a result. Aim: To determine how three distinct restorative materials (Ever X Flow, Cention forte, and Bio-C sealer ION) assist in resisting fracture endodontically treated teeth using a universal testing machine. Materials and Method: This study used fifty human mandibular premolars to investigate the effect of different intraorifice barrier cavity fillings on fracture resistance. The roots were prepared and obturated with gutta-percha and AH Plus sealer. The coronal 3-mm of gutta-percha was removed to receive the intraorifice materials, except for Group I which had a fully obturated root canal without intraorifice barrier cavity preparation. The roots were then divided into different groups based on the type of intraorifice barrier cavity filling used. All groups underwent thermo-cycling aging before fracture resistance analysis was performed. Results: Generally, Fracture resistance of endodontically treated teeth was significantly affected by the type of intraorifice barrier at(p<0.05); the results indicated that Group II showed the least fracture strength among all groups, While Group III (Ever X Flow) showed maximum fracture resistance followed by Group IV (Cention forte), Group I (positive control) and finally Group V (Bio-C sealer ION). Conclusion: Within the limitations of the current investigation, using Ever X Flow, Cention forte, and Bio-C sealer ION as an intra-orifice barrier may help strengthen teeth that have undergone endodontic treatment. When compared to the positive control group ((Fully obturated root canal without intraorifice barrier cavity preparation), the Bio-C sealer ION did not significantly increase the fracture resistance of endodontically treated roots.
