Background: An inappropriate filling while obturation results in re-entry and re-invasion of microorganisms into the root canal system that irritates the periapical area and compromises the success of treatment . The aim of the present study was to compare the apical microleakage of calcium hydroxide sealer and MTA based sealer. Materials and Methods: The present study was conducted in the department of endodontics for a period of 8 months. Decoronation of the teeth were done and then they were embedded in alginate containing containers. Preparation of the root canals was done using endo access bur and K files. NiTi pro taper rotary files were used for biomechanical preparation till size F2. Irrigation was done using 5.0% sodium hypochlorite and EDTA was kept in root canals for 4 minutes. The linear dye penetration was estimated from root apex to the most coronal level under Stereomicroscope. All the data thus obtained was arranged in a tabulated form and analyzed using SPSS software. Mann-Whitney test was used for statistical analysis. Results: 40% (n=12) teeth were lateral incisors, 33.3% (n=10) were central incisors. The mean penetration in group I was 0.64+/-0.22. The mean penetration in Group II was 1.14+/-0.21. On applying statistical analysis there was a significant difference between them as the p value was less than 0.05. Conclusion: The study showed that sealing capacity of calcium hydroxide was significantly better than that of MTA. Key Words: Biomechanical, Decoronation, sealer
