【 摘 要 】

Aim: This study investigated the physicochemical properties i.e. water sorption (Wsp) and solubility (Wsl) of one experimental composite in comparison with four commercially available materialsused for direct restorations. Material and Methods: Disc-shaped specimens of each material were prepared and investigated according to the ISO standard 4049:2000. Results: The experimentalcomposite had similar water sorption values with the trade-mark composites after 1 day storage. Significant differences regarding Wsp were found after 7 days and respectively 1 month of immersion (p<0.05). Similarities between the experimental composite and the trade-mark materials were observed regarding Wsl. Conclusion: The Wsp and Wsl values of the experimental material as well as of the trade-mark composites are in accordance with ISO standard 4049:2000, that is Wsp <40 μg/ mm3 and Wsl <7.5 μg/mm3 .
