Aim: To evaluate and compare the ability of two MTA based sealers: MTA Plus and EndoSeal MTA and an epoxy resin based sealer: AH Plus, to enhance the fracture resistance of root canal treated teeth.
Materials and Methods: Sixty-five single rooted mandibular premolars were decoronated at cementoenamel junction and were randomly divided into five groups: two control (n = 10) and three experimental (n = 15). Biomechanical preparation of root canals was done using Hero Shaper rotary files along with 3% sodium hypochlorite irrigation. Obturation was done using gutta percha with different sealers according to the groups- AH plus (group 3), EndoSeal MTA (group 4) and MTA Plus (group 5). Fracture resistance of the roots was evaluated using a Universal Testing Machine (UTM) under vertical loading.
Statistical Analysis: Inter-group comparison was done using One way analysis of variance (ANOVA) and Post-hoc bonferroni test.
Results: Among the three experimental groups, highest fracture resistance was shown by group 3 followed by group 4 then group 5. There was no statistically significant difference between group 3 and negative control group. Group 5 was not statistically significant than the positive control group.
Conclusion: EndoSeal MTA has the potential to reinforce root canal treated teeth and it was comparable to AH Plus.
