Scoring criteria: • 0 = No dye penetration • 1 = Dye penetration between the restoration and the tooth into enamel and dentin • 2 = Dye penetration between the restoration and the tooth in the enamel and dentin • 3 = Dye penetration between the restoration and the tooth into pulp chamber Results: The data were analyzed with nonparametric test (Kruskal-Wallis test; p < 0.005). There was no significant difference between the three restorative cements. The results showed that conventional GIC exhibited (type II) least microleakage than that of zirconomer, amalgomer CR, and maximum with zirconomer. Amalgomer CR exhibited more microleakage than conventional GIC. Conclusion: Within the limitations of this study, none of the material was free from microleakage. Although the new materials have certain advantage of strength, they lack microleakage.
