Sealing ability of a dentin bonding agent Scotchbond, used as a root-canal sealant, was tested and compared with a control group without a sealant, by dye penetration and SEM study. In both the groups, gutta percha filling by lateral condensation was given. It was seen that at 1 day, the leakage was equivalent in both the groups but at 7th day, the leakage had decreased significantly in experimental group (mean dye penetration 1.06) compared to the control group (mean dye penetration 11.64). On SEM study, close adaptation between gutta percha cones and canal walls was seen in the experimental group but in the control group, distinct voids between the canal walls and filling were found.
