Sixty anterior teeth with single root and root canal were selected for this study. Regtrograde sealing ability of three materials-silver amalgam, glass-ionomer and cermet cement was evaluated and compared in-vitro under scanning electron microscope. The materials were (I) silver amalgam (Solila nova), (ii) glass ionomer cement (Fuji ii) and (iii) cermet ionomer cement (Ketac silver). All the materials were used according to the manufacturers' direction. The photomicrographs of scanning electron microscope (500 magnification) of silver amalgam showed more gap than glass ionomer and cermet ionomer cements. In this study, cermet glass ionomer showed the least microleakage and the best sealing ability.
