Objective: The study was aimed to evaluate effects of water sorption, solubility and staining solution on the color stability of resin-modified glass ionomer.
Materials and Methods: Specimens for evaluation of water sorption, solubility and color stability methods were fabricated with resin-modified glass ionomers. L*a*b* values of color stability methods were recorded with a Xrite Bench top spectrophotometer. Specimens of color stability method were placed in staining solutions for 2 weeks. After storage, specimens were cleaned and L*a*b* measurements were remeasured. Data were analyzed by Kruskal-Wallis test and Spearman test.
Results: Regarding water sorption, materials ranked: Riva Light Cure> GC Fuji II LC> Ketac™ N100. Regarding solubility, materials ranked: Ketac™ N100> Riva Light Cure> GC Fuji II LC. After storage for 2 weeks, there was a positive correlation between water sorption and ΔE* of color stability. There was no signigicant difference between solubility and color stability.
Conclusion: Within the limits of this study, water sorption of resin-modified glass ionomer may effect on color stability, but solubility of resin-modified glass ionomer may not effect on color stability.
