ABSTRACT

Background For improving the physical characteristics of the original materials, additions of metal powders were introduced. The first such suggestion was a silver alloy and GIC admixture, with the subsequent emergence of materials incorporating fine metal particles sintered onto the cement-forming glass to form ceramic-metal materials. Hence; the present study was undertaken for assessing microleakage using metal modified and conventional glass-ionomer cement in permanent teeth. Materials & methods A total of 20 non-carious freshly extracted maxillary premolars were included in the present study. Mechanical debridement was done followed by preparing of all standard class I cavities. All the specimens were divided into two study groups with 10 specimens in each group as follows: Group 1: Conventional GIC; and Group 2: Metal modified GIC. The aqueous and non-aqueous pastes were mixed as per manufacturer's instructions and the mixture was placed into the cavity following two-step incremental techniques. This was followed by immersion of the specimens in 2% methylene blue dye for 24 hours. All the specimens were then analysed under stereomicroscope for assessment of microleakage followed by evaluation with SPSS software. Results While comparing statistically, it was observed that mean microleakage was significantly higher for metal modified GIC group in comparison to the conventional GIC group. Conclusion Conventional GIC is of superior quality in comparison to metal modified GIC in controlling microleakage in permanent dentition
