Aim: Present study aimed to comparatively evaluate Compressive strength (CS) and Diametral tensile strength (DTS) of Zirconomer with conventional GIC and Amalgam. Materials and Methods: A total of 90 specimens (n=90) were prepared with three materials –Zirconomer, GIC, Amalgam. Compressive strength, diametral tensile strength, and shear bond strength were evaluated after 24 h using Instron Universal Testing Machine. Specimens were submitted to CS and DTS test in each period, namely 1 hour, 24 hours and 7 days. The test was carried out in a universal testing machine with a cross head speed of 1.0mm/min. The maximum load required to fracture the specimen was recorded and calculated. The results obtained were statistically analyzed. Results: GIC had the least value of compressive strength and diametral tensile strength when compared to amalgam and Zirconomer at 3 different time interval i.e, after 1hr, 24hr and 7 days showing statistical significant difference at value of P = 0.05. Between amalgam & Zirconomer, Amalgam had better compressive strength and diametral tensile strength compared to Zirconomer at 3 different time interval there was no statistical difference.(P=0.05). Conclusion: The present study suggests that the addition of zirconia to the GIC has improved its mechanical properties as amalgam. Hence, zirconomer improved can be used as posterior restorative material.
