Background: Luting cement provides the connection between crowns and tooth structure. The sensitivity, solubility, and decomposition stages of the cement after the hardening stage are still subjects of relative controversy. These characteristics could lead to a poor connection between the braces and the teeth, increased probability of decay, and decalcification. The present study aimed to evaluate the adsorption and solubility of ۴ types of glass ionomer cement.Methods: Four luting cements were examined. A total of ۱۰ specimens were prepared for each material following the manufacturer’s instructions, and the sorption and solubility were measured in accordance with the ISO ۴۰۴۹’s. Specimens were immersed in artificial saliva for ۳۰ days, and were evaluated for sorption and solubility by first weighting them before incubation (W۱), then immersing them in artificial saliva, dehydrating them in an oven for ۲۴ hours, and weighing them again (W۲ and W۳, respectively). The data were analyzed using SPSS software version ۲۱. One-way analysis of variance (ANOVA) followed by Tukey post hoc test was used to examine the differences among groups (α = ۰.۰۵).Results: As for the both sorption and solubility, there was a significant interaction between the sorption and solubility of all materials (P < ۰.۰۰۱). The sorption values in artificial saliva were highest for glass ionomer cement Riva Luting followed by GC Fuji ۱ and Cavex, whereas the least value was observed for Meron (P < ۰.۰۰۰). As for solubility, it was significantly higher in Cavex followed by GC Fuji۱ and Meron, but it was significantly lower in Riva Luting.Conclusions: It was determined that the weight changes of glass ionomer cements significantly varied among all the materials. Riva Luting followed by GC Fuji ۱ had the highest water sorption, and the solubility was significantly higher in Cavex followed by GC Fuji۱. Meron improved both water sorption and solubility properties among all glass ionomer cements.
