To compare the effectiveness of AH Plus, MTA Fillapex sealer and ZOE based sealer on the resistance of endodontically

treated teeth to vertical root fracture. .Materials and Methods: sixty freshly extracted mandibular premolars were

used for the study. The length was standardized and all the teeth were biomechanically prepared and divided into five

different groups based on the type of root canal sealers used. Group I: negative control group (only RCO done),Group II: positive control (only BMP

done) Group III: AH plusroot canal sealer + gutta percha, Group IV: MTA Fillapex sealer + gutta percha, Group V: Zinc oxide?eugenol sealer + gutta

percha, The teeth were embedded in acrylic resin blocks and compressive strengths were measured using universal testing machine (Instron).

Statistical Analysis Used: One?way ANOVA, unpaired t? test done.Result:Multiple comparisons were performed among all five groups. Group

1 and group 2 show highly significant values and group 1 and group 5 values are significant value. There were significant differences between

group 2 and 3(p < 0.001) and between group 3 and group 5(p < 0.033).Conclusions: From this study, it has been concluded that AH Plus requires

more force to induce fracture amongst all sealer groups followed by MTA Fillapex and ZOE sealer. AH Plus has the ability to bond directly to root

canal dentin which creates a monoblock effect that increases the resistance to fracture and provides the best possible seal.
