A Comparative in vitro Evaluation of Vertical Root Fracture Resistance of Endodontically Treated Teeth using Different Obturating Materials

Abstract

ABSTRACT Aim To compare the vertical root fracture resistance of endodontically treated teeth obturated using different obturating materials. Materials and methods Decoronated roots of 75 single canal lower second premolar teeth were divided randomly into 5 groups. The first group (Group I) served as a negative control. The remaining four Groups were cleaned and shaped using ProTaper Endodontic rotary files and obturated with guttapercha + TubliSeal EWT sealer (Group II), ThermaFil + AH Plus sealer (Group III), RealSeal + RealSeal sealer (Group IV) and GuttaFlow obturating system (Group V). The roots were then embedded in acrylic resin blocks and subjected to vertical load until fracture with a spreader in a universal testing machine and the forces were recorded. Results Fracture resistance of group I > group IV > group V > group III > group II, which were statistically significant. Conclusion Obturation of roots with resin based obturation material—RealSeal had increased VRF resistance compared to the gutta-percha obturation systems. Clinical significance Obturation of the root canals with resin based obturation system—Resilon reinforces the fracture resistance of endodontically treated teeth and contributes to the overall success of the endodontic treatment.
