Biocompatibility test of microfilled resins and composites for core use in vitro.
Experiments were carried out in an in vitro environment by the cell colony forming method in order to study the cytotoxicity to HeLa cells of set specimens of 3 MFRs and 4 composites for core use. In the experiment each of the specimens was extracted in a tissue culture medium for 2 weeks in dynamic environment with a specimen freely moving. With both MFRs and the composites for core use cytoto...
متن کاملbiocompatibility of dental composites resins
dental materials that are used in dentistry should be harmless to oral tissues, so they should not contain any leachable toxic and diffusible substances that can cause some side effects. reports about probable biologic hazards, in relation to dental resins, have increased interest to this topic in dentists. the present paper reviews the articles published about biocompatibility of resin-restora...
متن کاملBiocompatibility test of light-cured composites in vitro.
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 bi...
متن کاملIn vitro wear of microfilled and visible light-cured composites.
Wear of microfilled composites, a visible light-cured composite, and a conventional composite were characterized by two-body abrasion and single-pass sliding. There were differences in abrasion rates among the materials. Tangential forces, wear track widths, and surface failure modes were different among materials. Wear characteristics are combinations of these properties.
