  • Title: [A study on the cytotoxicity of six filling materials in vitro].
    Author: Yu W, Shen J, Sun W.
    Journal: Zhonghua Kou Qiang Yi Xue Za Zhi; 1997 Jul; 32(4):246-8. PubMed ID: 10680517.
    Abstract:
    This paper deals with the cytotoxicologic analyses on 6 filling materials with morphology of cells, ultraviolet light spectrophotometry and incorporation test using mouse L-929 fibroblasts labelled 3H-TdR. The results showed that the cytotoxicity of Silver amalgam and the Gallium-Silver alloys, which were produced by mixing the conventional dental alloys powder or high copper alloys powder with Gallium, was significantly stronger than that of light curing composites and the Gallium-Silver alloys that were produced by the spherical amalgam alloys powder and Gallium. It suggested that the level of mercury and copper in the alloys can influence their cytotoxic properties.
