Relative Assessment of Fracture Resistance of Endodontically Treated Teeth with Epoxy Resin-Based Sealers, AH Plus, MTA Fillapex, and Bioceramic Sealer: An In vitro Study.

Aim: This study aims to analyze and compare the fracture resistance of endodontically treated extracted teeth with epoxy resin-based sealer AH Plus, MTA Fillapex, and Bioceramic Sealer. Materials and Methods: Single-rooted mandibular premolars (sixty) were divided into three groups (n = 20 each) after decoronation at cementoenamel junction. Root canal preparation was carried out using ProTaper rotary files, and sodium hypochlorite in 3% concentration was used for irrigation. Finally, obturation was accomplished with AH plus (Dentsply, Germany) (Group 1), MTA Fillapex (Angeles, Brazil) (Group 2) and Bioceramic (Brasseler, USA, Savannah, GA) (Group 3) sealers and gutta-percha. Fracture point in the root was recorded using universal testing machine. The data were analyzed statistically using one-way analysis of variance. This was followed by pair-wise comparison using Tukey's post hoc test. Results: Bioceramic Sealer showed better fracture resistance. This was followed by MTA Fillapex and AH Plus. However, the results among the three groups were not statistically significant. Conclusion: The highest fracture resistance was offered by Bioceramic Sealer when compared with MTA Fillapex and AH Plus. [ABSTRACT FROM AUTHOR]
