Background: Removal of all the material inside the canal is a necessity for success of the root canal procedures. The present study was conducted to compare effectiveness of different root canal irrigating solution. Materials & Methods: The present study was conducted on 120 freshly extracted periodontally week mandibular molars. All teeth were divided into 4 groups of 30 teeth each. In group I teeth were irrigated with 17% EDTA, in group II with 5.2% NaOCl, in group III with MTAd and in group IV with 2% chlorhexidine. The samples were prepared and cut into 2 halves. They were observed under a scanning electron microscope (SEM). The photomicrographs were recorded and evaluated with a scoring system. Results: In group I, smear score at cervical third was 1.16, at middle third was 1.20 and at apical third was 1.35. In group II, at cervical third was 1.67, at middle third was 1.78 and at apical third was 1.92. In group III, at cervical third was 1.65, at middle third was 1.68 and at apical third was 1.90. In group IV, at cervical third was 2.04, at middle third was 2.12 and at apical third was 2.25. The difference was non- significant (P> 0.05). Conclusion: Different irrigating solutions such as EDTA, 5.25% NaOCl, MTAd and 2% chlorhexidine found to be equally effective in root canal therapy.
