--- The aim of this study was to determine differences in sorption and solubility of a conventional glass ionomer cement and a resin-modified glass ionomer cement at 7, 15 and 30 days. Materials and Methods: 24 discs of each material were prepared and divided into 3 subgroups (7, 15 and 30 days) of 8 discs, randomly selected. The protocol established by the ISO 4049 for water sorption and solubility test was used. The discs were placed in an oven at 37 °C to constant mass (m1), then were immersed in 10 ml of distilled water. The discs were removed from the distilled water on the days indicated, and weighed (m2), then dried and re-weighed (m3). At the end of these process, their morphology was evaluated in a scanning electron microscope. Results and Conclusions: The sorption and solubility calculation was performed using mathematical expressions interrelated. The Krustal Wallis test, T-Student and U. de Mann-Whitney (p<0,05) showed statistically significant differences in both groups for both sorption and solubility. The resin-modified glass ionomer cement showed the highest sorption values (142,3195 ± 13,9402), while the conventional ionomer obtained the highest solubility values (36,4286 ± 14,5941) Keywords: Sorption, solubility, glass ionomer cement, resin-modified glass ionomer cement.
