ABSTRACT
Since water sorption of any restorative material can result in expansion of the restoration, which would be detrimental to the restoration, it is important to limit the amount of water absorbed. In addition, solubility of restorative materials is of concern, since inorganic ions can leach into the surrounding environment resulting in breakdown of the restoration. The aim of this study was to measure and compare water sorption and solubility values of Biodentine new direct restorative material with other conventional restorative materials
Three direct restorative materials were selected for this study: Biodentine [Septodont,France], composite [masterfill], GIC[Kemdent, UK]. Ten specimens were prepared from each restorative material [n=10] using a stainless steel mold of 15 mm in inner diameter and 1 mm in thickness. Each restorative material was prepared according to manufacturer's instructions. Water sorption and solubility of each specimen was calculated by weighting the samples before and after immersion in water for 15 days and desiccation. Data were analyzed with one way ANOVA and t-test at [0.05] level of significance
One way ANOVA that, there were statistically significant differences between the tested groups [P<0.05] in both sorption and solubility values
Within the limit of this study, Biodentine restorative material showed an intermediate sorption and solubility values between Kemdent GIC restorative and Master Fill composite and due to this result the material [Biodentine] is not recommended to be used as a final direct restorative material but recommended to be used as abase only
