Munish Dheeraj, Suksham Johar, Tania Jandial, Henna Sahi, Saloni Verma

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.
Key words: Compressive strength; diametral tensile strength; glass ionomer cement; shear bond strength; Zirconomer.
