The purpose of this study was to find out the effects of the presence and absence of the smeard layer upon penetration of root canal sealers into the dentinal tubules. Penetration of Zinc oxide eugenol, Kalzinol and Sealapex was studied with the help of SEM, in the coronal, middle and apical thirds of the root canal after filling the root canals both in the presence and absence of the smeard layer. Presence of the smeared layer did not allow the sealers to enter the dentinal tubules. After the removal of the smeared layer, Zinc oxide eugenol penetrated the dentinal tubules in coronal and middle thirds and Sealapex in coronal third only. Kalzinol did not display any penetration. No sealer was able to penetrate the apical dentinal tubules.
