Comparitive evaluation of compressive strength and diametral tensile strength of zirconomer, ketac molar and type ix gic – an in –vitro study

Introduction: The quest for better restorative material still continues which has led to newer materials introduced having better mechanical properties such as better marginal seal, biocompatibility, high compressive and diametral tensile strength in evolution. GIC is no exception to it; a newer class of restorative zirconia reinforced glass ionomer is being evolved. Aim: Comparative evaluation of compressive and diametral tensile strength of Zirconomer, Ketac Molar and Type IX GIC. Method: These three study groups will be evaluated for compressive strength and diametral tensile strength, by preparing the specimens using cylinder moulds. All these specimens was subjected to the Universal Testing Machine. The data obtained from the study will be compiled, tabulated and analyzed statistically. Result: Conventional GIC has higher compressive strength (p=0.805) and tensile strength (p=0.045) followed by Zirconomer and Ketac molar. Conclusion: Conventional GIC has better compressive strength and tensile strength followed by Zirconomer and Ketac molar.
