Aims and Objectives: To study the possible correlation of dentinal tubule penetration and microleakage by three root canal sealers: AH26, zinc oxide eugenol (ZOE), and mineral trioxide aggregate (MTA) using a dye leakage and scanning electron microscopy (SEM) methods. Materials and Methods: Fifty-one maxillary anterior teeth with completely formed apex divided into three groups. Root canals were enlarged till No. 60 K-file using step-back technique. Alternate 5.25% and 17% ethylenediaminetetraacetic acid irrigants were used and obturated with gutta-percha and one of the three sealers: MTA, AH26, and ZOE. The extent of leakage was determined under stereomicroscope after immersion in methylene blue and also observed the tubular penetration of sealer under SEM. Results: AH26 had lower microleakage scores than the other sealers, and MTA demonstrated the least penetration (P < 0.05). Conclusion: There was an inverse relationship between microleakage and tubular penetration of root canal sealers. Deeper the penetration, lesser is the leakage.
