Objectives To evaluate and compare the compressive strength CS diametral tensile strength DTS sorption and solubility of Zirconomer Improved ZI with GIC type IX.Methods This is an experimental in vitro study. Forty specimens of ZI and GIC type IX 20 each were prepared using a Teflon mould and were stored at 37ordmC for one hour. These specimens were then subjected to CS DTS sorption and solubility testing. Results were then analysed using One way analysis of variance ANOVA.Results CS and DTS were significantly higher for ZI compared to GIC type IX. Sorption and solubility values were lesser for ZI compared to GIC type IX. Conclusion The study concluded that ZI cement is a useful dental material that can be used to restore stress-bearing areas due to its increased strength low solubility and sorption rates. As a restorative cement for stress-bearing areas zirconia-reinforced GIC has considerable promise for usage in dentistry. This is due to its considerable strength as well as poor solubility and sorption rates.
