Abstract

Introduction: It has been observed that the teeth which got treated endodontically are getting fractured easily particularly when we compare it with vital teeth. In current obturation systems Gutta-percha which has the epoxy resin-based AH plus sealer, is considered the gold standard. Our aim here is to compare the AH Plus sealer effect with that of BioRoot RCS in reference to resistence of fracture when roots are getting filled with them in combination with gutta-percha. Method: Thirty extracted teeth are used. These teeth are without caries. These are single rooted too and at the same time human mandibular premolar. To store the teeth we used de ionized water whereas the temperature has be maintained at 4 °C. For fracture resistance test, roots were mounted in acrylic resin blocks. The middle third of each root was coated with uniform thickness of light body rubber base to provide a simulated periodontal ligament then each root was embedded in acrylic resin cylinder using self-cured acrylic resin except for the coronal 5 mm. Result: Bio Root RCS had the highest mean fracture resistance of 254.15N, followed by that of AH Plus group with a mean of 229.5 N, then that of the control group 200.40 N. Conclusion: The present study lead us to conclude that Bioroot RCS are higher fracture resistance than the AH Plus.

Key words: Endodontically, obturation systems, Gutta-percha, AH Plus sealer, BioRoot RCS
