They were then divided into 6 subgroups (n=5) to assess their water solubility after 1 week and 8 weeks, water sorption after 1 week and 8 weeks, and acid solubility after 1 week and 8 weeks. The samples were then weighed, and placed in vials containing artificial saliva or lactic acid and incubated at 37&deg;C for 1 week or 8 weeks according to specimen grouping. Afterwards, each specimen was weighed again. Sorption and solubility were calculated according to difference in weight of the samples. Data were analyzed by two-way ANOVA(alpha=0.05). </span></span></span></span><br> <span style="font-size:13pt"><span new="" roman="" style="font-family:" times=""><b><span style="font-size:9.0pt"><span style="font-family:" verdana=""><span style="color:#2e74b5">Results: </span></span></span></b><span style="font-size:9.0pt"><span style="font-family:" verdana="">RMGI showed greater water solubility and sorption compared with ACTIVA BioACTIVE liner after 1 week of storage (P=0.00). No significant difference was found in water solubility (P=0.64) and sorption (P=0.15) after 8 weeks of storage. There was no significant difference in acid solubility of RMGI and ACTIVA BioACTIVE liner after 1 week (P=0.30) or 8 weeks of storage (P=0.60) </span></span></span></span><br> <span style="font-size:13pt"><span new="" roman="" style="font-family:" times=""><b><span style="font-size:9.0pt"><span style="font-family:" verdana=""><span style="color:#2e74b5">Conclusion:</span></span></span></b> <span style="font-size:9.0pt"><span style="font-family:" verdana="">Water sorption and solubility of RMGI were greater than those of ACTIVA BioACTIVE within the first week after setting but they were similar in long-term assessment.
