Aim: This study aimed to evaluate wear, microhardness, water sorption, and solubility of glassionomer cement modified with precured nanofilled composite.
Subjects and Methods: Glass ionomer cement and nanofilled composite were used in this study. Glass ionomer cement was modified with precured nanofilled compositewith different concentrationsas follows: 0 wt%, 5 wt%, 10 wt%, 15wt% for the groups I, II, III, IV respectively. Wear, microhardness, water sorption, and solubility have been investigated. The data were statistically analyzed by one-way ANOVA and Tukey's HSD analysis at a significant factor of α = 0.05.
Results: Regarding wear, water sorption, and solubility, the lowest value was for group IV, while the highest value was for group I.For, microhardness,the highest value was for group IV, while the lowest value was for group I.
Conclusions:As the concentration of precured nanofilled composite powder increased in glass ionomer cement, the microhardness have been increased while wear, water sorption and solubility have been decreased.
