Purpose: Evaluation of water sorption and solubility of contemporary resin-based filling materials. Methods: Specimens of Herculite (HE), Point 4 (P4), TetricCeram (TC), Miris (MI), TetricCeram HB (HB), Solitaire 2 (SO), SureFil (SU), Definite (DE), Admira (AD), Dyract AP (DY), Compoglass F (CO), and TetricFlow (TF) were prepared according to ISO 4049. Water sorption and solubility were measured after water storage at 37°C for 7 days. Results: Water sorption was HE 14 μg mm-3, P4 17 μg mm-3, TC 12 μg mm-3, MI 13 μg mm-3, HB 9 μg mm -3, SO 18 μg mm-3, SU 9 μg mm-3, DE 14 μg mm-3, AD 27 μg mm-3, DY 19 μg mm-3, CO 23 μg mm-3, and TF 19 μg mm-3. Solubility was HE 3 μg mm-3, P4 3 μg mm-3, TC 1 μg mm -3, MI 0 μg mm-3, HB 0 μg mm-3 SO 3 μg mm-3, SU 0 μg mm-3, DE 1 μg mm-3, AD 2 μg mm-3, DY 4 μg mm-3, CO -2 μg mm-3, and TF 1 μg mm-3, Conclusion: All materials met the corresponding requirement in ISO 4049. Filler load negatively correlated with water sorption but not with solubility. There was an influence of the resin matrix, too. No significant differences were found between composites, ormocers, and compomers.
