Özet

Background: The luting cement around the margins of the indirect restorations is in contact with oral and sulcular fluids. Water sorption of the luting cements can also lead to material deterioration and discoloration. The aim of this study is to evaluate the water sorption and the solubility of three different resin cements. Methods and materials: A totally 30 disc shaped specimens (n:10) were prepared from one light-cure (Variolink Esthetic LC, Ivoclar Vivadent) and two dual-cure resin cements (Variolink Esthetic DC, Ivoclar Vivadent) one of which is self-adhesive (Rely X U 200, 3M ESPE). Specimens from each group were kept in a silica gel containing desiccator and weighed on an analytical balance (m1). Then the specimens were stored in closed flasks containing 2 ml distilled water in an incubator at 37oC for seven days. After the storage period, the specimens were weighed again to determine the value of m2, then they were placed into the desiccator to eliminate the absorbed water. The specimens were weighed daily until reaching a constant mass (m3). Percentages of the water sorption and solubility were calculated. Data was analysed statistically with Kruskal-Wallis One Way Analysis of Variance. Results: Water sorption (%) (p = 0,07) and solubility values (%) (p = 0,28) of the three cement groups were not statistically significant. Conclusion: Curing type or adhesive properties of the cements used for the study, did not differed in terms of water sorption or solubility.
