Abstract:Though aging of resin composites has been the subject of several investigations, the correlation between strength and water uptake has not been established. Therefore, the purpose of the present study was to determine whether a statistically signifi cant correlation exists between biaxial fl exural strength and weight gain due to water uptake for two commercial restorative composites, one methacrylate-based and one silorane-based. Discs (15 mm in diameter by 1 mm thick) were made with either Filtek Z250 or Fil… Show more
