Comparison of Compressive Strength and Microleakage of Zirconia Reinforced Flowable Composite and Zirconia Reinforced GIC in Class V Cavities - An In-Vitro Study

Dr. L Krishna Prasada | Dr Gunjan Chawla

Abstract: This study investigates the comparative efficacy of zirconia - reinforced glass ionomer cement GIC and zirconia - reinforced flowable composite in restoring Class V cavities. Specifically, it evaluates their compressive strength and microleakage properties. The research comprises an in vitro analysis of 48 samples divided into subgroups for each material type. The zirconia - reinforced GIC demonstrated higher compressive strength, while the zirconia - reinforced flowable composite exhibited significantly lower microleakage. These findings suggest that while zirconia - reinforced GIC offers superior strength, the flowable composite is more effective in minimizing leakage. This study contributes to the field of restorative dentistry by providing insights into the performance of these materials in Class V cavity restorations, highlighting the need for further research, particularly on the relatively new zirconia - reinforced flowable composite.
