Color stability, roughness, and water sorption/solubility of glass ionomer–Based restorative materials

Abstract

OBJECTIVES: The aim of this study was to investigate the effects of various drinks on color stability and roughness of glass ionomer cement-based/-containing restorative materials and water sorption/solubility behavior of them. MATERIALS AND METHODS: days. After a total immersion time of 28 days, the specimens were dried to a constant mass, in a desiccator for 28 days. Each specimen was measured using a digital electronic caliper. Data were statistically analyzed (P < 0.05). RESULTS: ) had the highest. CONCLUSIONS: The compositions of restorative materials play key roles in their color stability, surface roughness, and water sorption/solubility.
