Introduction: Successful root canal therapy requires a hermetic three dimensional obturation of root canal system. The role of sealer is critical for the sealing ability of obturation material and many new root canal sealers have been developed to fill the residual gaps between gutta percha and canal wall.

Objectives: To compare the marginal adaptation of EndoSequence BC sealer, MTA Fillapex & ProRoot ES root canal sealers to dentin by using SEM.

Methods: Sixty extracted teeth were selected, decoronated, instrumented in crown down fashion using protaper rotary file system upto size F3. Samples were divided into three groups: Group I-EndoSequence BC sealer. Group ll-MTA Fillapex, Group IIl-ProRoot ES sealer. Marginal adaptation of sealers to root dentin was evaluated at coronal and apical halves using scanning electron microscopy (SEM). Maximum and minimum marginal gap values (μm) at sealer and dentin interface were recorded and mean was calculated.

Results: On statistical evaluation using one way ANOVA and Kruskall Wallis test followed by Post Hoc test showed no statistically significant difference (p>0.05) among the three groups at apical halves of root sections. At coronal halves there was no statistically significant difference between Group II and Group Ill. However, statistically significant difference was found when Group I was compared with Group II and Group III at coronal halves of root sections

Conclusion: The current in vitro study showed that Endosequence BC sealer along with C point group showed least microgap between root canal sealer and dentin when compared with MTA Fillapex sealer and ProRoot ES sealer groups.
