Radiopaque fluoride releasing vlc dental composites and the use of specific fillers therein

Abstract From the Canadian patent

One component, visible light-cured dental restorative compositions having fluoride release properties for the purpose of reducing the chances of secondary caries are provided. The compositions comprise a blend of a major proportion of inorganic particulate filler comprising a fluoride leachable Barium glass and a minor proportion of an activated resin component comprising the reaction product of a vinyl ester of a polyglycidyl ether having secondary hydroxyl groups and an unsaturated urethane reacted through the secondary hydroxyl groups, a diluent monomer and a photosensitizing system comprising an alpha diketone and an amine reducing agent.
