Abstract

The in vitro cytctoxicity to HeLa S3 cells of set specimens of five commercially available light-cured composites was examined by the cell colony-forming method for 6 weeks. Both visible and ultraviolet light-cured composites showed moderate to strong cytotoxicity in the early stage of the experiment, followed by rapid disappearance of cytotoxicity. The light-cured composites showed in vitro biological behaviors similar to those of conventional composites, MFR and composites for core use.
