A glass-ionomer-silver cermet cement was comparatively evaluated with a conventional fissure sealant for such mechanical properties as compressive strength, tensile bond strength, and wear resistance. The mean compressive and tensile bond strength values of the Ketac-Silver group were found to be significantly lower than those of Delton sealant group. However, the wear percentage in the Delton group was higher than that in the other group. Nevertheless, the results indicated that Ketac-Silver cannot be used as an alternative to bis-GMA resin fissure sealant.
