Comparative Evaluation of Fracture Resistance of Endodontically Treated Teeth with Epoxy Resin-based Sealer AH Plus and Zinc Oxide Eugenol: An In Vitro Study
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2018, Vol 5, Issue 12
Abstract
Introduction: Endodontic treatment while trying to save a tooth reduces the tooth structure which, in turn, reduces the fracture resistance of the tooth. Certain root canal sealers by improving the bond between the root canal filling materials and the tooth structure increase the fracture resistance of the tooth. Aim: This study aims to evaluate and compare the fracture resistance of endodontically treated teeth obturated with gutta-percha using two sealers, AH Plus and zinc oxide eugenol. Materials and Methods: A total of 60 single-rooted mandibular premolars, decoronated at cementoenamel junction, were divided into two groups (n = 30 each). Cleaning and shaping of root canals were done using ProTaper rotary files and 3% sodium hypochlorite irrigation. Obturation was done using sealers, AH Plus in Group 1 and zinc oxide eugenol in Group 2 and gutta-percha. The teeth were subjected to vertical loading using a universal testing machine, and the readings were recorded at the point at which fracture of the roots occurred. Results: According to the study, it was found that AH Plus showed better fracture resistance than zinc oxide eugenol. Statistically significant difference was found between the two groups. Conclusion: AH Plus showed better fracture resistance than zinc oxide eugenol when used as root canal sealer with gutta-percha.
