Background: Microleakage is one of the significant causes for endodontic failure. The present study compared sealing ability of zinc oxide eugenol sealer, AH Plus and Apexit. Materials & Methods: The present study was conducted on 90 recently extracted periodontally weak non carious teeth. The teeth were divided into 3 groups of 30 teeth each. Group I was conventional zinc-oxide eugenol group, group II was AH Plus group and group III was apexit. Methylene blue dye solution 2% was poured into the each tube until the root was completely immersed into the solution. Teeth samples were sectioned longitudinally and the samples were studied under a stereomicroscope. The end point of dye infilteration was calculated as the point where dye no longer penetrated the obturating material. Results: The mean dye penetration in group I was 4.12 mm, in group II was 1.82 mm and in group III was 2.16 mm. The difference was significant (P< 0.05). Conclusion: There was significant difference in sealing ability of root canal filling materials. It was maximum in AH Plus group followed by apexit and zinc-oxide eugenol.
