Background; Dental materials used for permanent restorations are intended to replace lost and defective dental tissues, be chemically stable and inert in the oral environment. Aims and Objectives: To compare and evaluate the physical properties of Zirconia reinforced Glassionomer with two conventional restoratives. To analyze the mechanical properties of the cements being tested. Materials & methods; For the compressive strength 120 cylinders of 8 mm height and diameter 4 mm were prepared using split teflon moulds for each group. Group 1 ( Zirconomer), Group 11 (Hidence) Group iii (Posterior Extra) which were subjected to 1 day (24 h) and 7 day interval storage and CS values were obtained. For the Shearbond strength testing 60 specimens was bounded to flat dentinal surface by positioning polyvinyl moulds. Then mounted samples were stored in distilled water for 24 h and then subjected to Shearbond strength test using Universal testing machine. Results; Results shows that all the three group’s shows that high Compressive strength but there was significant decrease in the mean CS in Hidence and Posterior extra groups at 7 day interval. Zirconomer reinforced GIC group showed highest Shearbond strength followed by Posterior extra group and least was seen in Hidence group and there was significant difference between Group 1 and Group 2. Conclusion; It can be concluded that Zirconomer reinforced Glassionomer at 7 days had no significant difference in the CS and at 24 hrs and good bond strength and sealing ability compared to other restoratives. Key words; Compressive strength, Shear bond strength, Zirconomer
