Dental glass ionomer cement composition

摘要

To provide a dental glass ionomer cement composition having excellent adhesion strength to a metallic prosthesis. A dental glass ionomer cement composition includes a copolymer (A), a fluoroaluminosilicate glass powder (B) and water (C). The copolymer (A) includes a polymer or copolymer of α-β unsaturated carboxylic acid, or includes a copolymer of α-β unsaturated carboxylic acid and one or more kinds selected from a group of acrylamide, acrylonitrile, methacrylic acid ester, acrylates, vinyl chloride, allyl chloride and vinyl acetate. In the copolymer (A), the number of molecules of α-β unsaturated carboxylic acid occupies 50% or more of the total number of molecules. The dental glass ionomer cement composition further includes a compound (D) which contains a sulfur atom in one molecule, includes a carboxylic group and an amino group and does not include a polymerizable group.
