The effect of different root canal sealers on the fracture resistance of endodontically treated teeth‑in vitro study.
Journal Title: International Journal of Dental Science and Innovative Research (IJDSIR) - Year 2019, Vol 2, Issue 1
Abstract
Aim of the study: To compare fracture resistance of endodontically treated teeth obturated with adhesive sealers like Endosequence BC, EndoREZ and AH plus with a thermoplasticized obturation technique. Methodology : A total of 60 Single rooted teeth were divided into three groups. The specimens were decoronated and standardized to a working length of 14 mm. The teeth in all groups were shaped using ProFile rotary files (Dentsply Maillefer, Ballaigues, Switzerland). Thermoplasticized Gutta Percha was used for all the teeth. The first group was obturated with Epoxy-based sealer AH Plus® (Dentsply, DeTrey, Germany) . The second group was obturated with EndoREZ® sealer (Ultradent, South Jordan, UT). The third group was obturated with Bioceramic sealer ( Endosequence BC®). Roots were then embedded into acrylic blocks and were then fixed into a material testing system and loaded with a stainless steel pin with a crosshead speed of 5 mm/min until fracture. Data obtained were statistically evaluated using one way ANOVA and post hoc test (Tukey’s test). The load at which the specimen fractured was recorded in Newtons. Results : Group III (Endosequence BC) exhibited the highest fracture force than Group I (AH plus) and Group II (EndoREZ). Conclusion : According to this study, teeth obturated with Endosequence BC sealers showed the highest fracture resistance and can be considered to be superior in terms of fracture resistance as compared to EndoREZ and AH plus sealers.
