Introduction: Complete fluid tight seal is important for successful endodontic treatment. It will be achieved by use of gutta percha
with sealer during obturation. Aim: Compare and evaluate microleakge of Sealapex, MTA Fillapex and Adseal using
stereomicroscope. Materials and Methods: Thirty single canaled human teeth were collected. Samples were separated into three
groups (n=10). Group I- Sealapex, Group II-MTA Fillapex, Group III- Adseal. Samples were examined under stereomicroscope for
sealing ability. Data obtained were statistically checked using One-way ANOVA test. Results and conclusion: Least microleakage was
found with Sealapex followed by Adseal followed by MTA Fillapex sealer. MTA Fillapex shows highest amount of leakage.
