Background: To assess the effect of two different root canal irrigating solutions (5.25% Sodium hypochlorite with 17% EDTA and 2% Chlorhexidine) on the apical sealing ability of three different root canal sealers, i.e. AH Plus, MTA Fillapex, and Endomethasone N under a light microscope. One of the major reasons for the failure of root canal treatment is apical microleakage. Maximum sealing ability and adhesion of sealer to dentin can be achieved by effective removal of smear layer. There are various types of root canal sealers being used in endodontics with varying rate of clinical success. Materials and method: Sixty-six freshly extracted single-rooted human mandibular premolar teeth, were selected for the study. Root canals were prepared in a step-back manner up to the working length to a master apical file size of # 45. Sixty-six samples were randomly divided into six experimental groups of ten samples each. Three samples were kept as positive, and three samples as a negative control group. Samples in Group 1,2 and 3 were irrigated using 5.25% Sodium hypochlorite followed by 17% EDTA and samples in Group 4,5 and 6 were irrigated using 2% CHX. Both control groups were irrigated using sterile saline. A lateral condensation technique was used to obturate all teeth. In Group 1 and 4 AH Plus sealer was used, and in Group 2 and 5 MTA Fillapex sealer was used whereas in Group 3 and 6 Endomethasone N sealer was used. The positive control group, i.e. Group 7, was obturated with gutta-percha without sealer and negative control group, i.e. Group 8 was not obturated. The 2 % methylene blue dye penetration method was used to measure leakage from the apical to the coronal extent, and raw data were statistically analysed. Results: Intergroup comparison showed that Group 1(1.56±0.34) exhibited the best sealing ability as compared to other sealer used in the study. Group 6 (3.65±0.37) showed the maximum amount of apical leakage. Conclusion: Within the limitation of the study, no sealer used in this study perfectly seal root apex. 5.25 % NaOCl followed by 17% EDTA and AH Plus sealer showed the best apical seal.
