摘要：Introduction: The use of GIC as a luting agent, restorative material and base resulted in its popularity among dentists. Aim: To assess the microleakage of conventional GIC with RMGIC material. Materials & Methods: The present in vitro study was conducted on 40 freshly extracted maxillary second premolars. Teeth were catagarised into two groups of 20 each. In group A, conventional GIC restorative material was used and in group B, RM-GIC material was used. By dye penetration test microleakage was evaluated at labial and lingual surfaces of teeth with stereomicroscope. Results: The mean microleakage in group A was 0.58± 0.12 and in group B was 0.92± 0.13. The mean difference in both groups found to be -0.56. Independent t- test showed significant difference between both groups (P< 0.01). Conclusion: The RMGIC exhibited higher microleakage as compared to conventional GIC.
