title: Water sorption and solubility of contemporary resin-based filling materials.
abstract: OBJECTIVE
  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 degrees C for 7 days.
  
  
  RESULTS
  Water sorption was HE 14 microg mm(-3), P4 17 microg mm(-3), TC 12 microg mm(-3), MI 13 microg mm(-3), HB 9 microg mm(-3), SO 18 microg mm(-3), SU 9 microg mm(-3), DE 14 microg mm(-3), AD 27 microg mm(-3), DY 19 microg mm(-3), CO 23 microg mm(-3), and TF 19 microg mm(-3). Solubility was HE 3 microg mm(-3), P4 3 microg mm(-3), TC 1 microg mm(-3), MI 0 microg mm(-3), HB 0 microg mm(-3), SO 3 microg mm(-3), SU 0 microg mm(-3), DE 1 microg mm(-3), AD 2 microg mm(-3), DY 4 microg mm(-3), CO -2 microg mm(-3), and TF 1 microg mm(-3).
  
  
  CONCLUSIONS
  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.
