Abstract
An object of the present invention is to provide a dental resin-reinforced glass ionomer cement composition which exhibit high surface curability even under wet conditions, which makes it difficult for the surface to become cloudy even if moisture comes in contact with at the initial stage of curing, exhibits high mechanical properties, low water absorption expansion and excellent coloring resistance in the set product and is also excellent in storage stability. The dental resin-reinforced glass ionomer cement composition consisting of a powder material and a liquid material, wherein the powder material contains (a) acid-reactive glass powder, the liquid material contains (b) water, (c) polymer of acidic group-containing polymerizable monomer, (d) hydroxyl group-containing (meth)acrylate-based polymerizable monomer and (e) tri or more functional (meth)acrylamide-based polymerizable monomer, and at least one of the powder material and the liquid material contains (f) polymerization initiator.
