  • Dental Cement - an overview | ScienceDirect Topics

    Resin-based materials have been used as dental cements and restorative materials. Because they are a combination of organic and inorganic phases, these materials are called resin composites. In vitro, freshly set chemically cured and light-cured resins often cause moderate cytotoxic reactions in cultured cells over 24 to 72 hours of exposure, although several newer systems seem to have minimal toxicity.
