the composition of a glass ionomer cement for dental paste type

摘要

A paste-type dental glass ionomer cement composition is disclosed as comprising a first paste comprising an alpha-beta unsaturated carboxylic acid polymer, water, and a filler not reactive with the alpha-beta unsaturated carboxylic acid polymer; and a second paste comprising a fluoroaluminosilicate glass powder and a polymerizable monomer free of an acid group, wherein at least one of the first paste and the second paste contains a polymerization catalyst. By employing a construction such that a dental glass ionomer cement composition comprising a powder component and a liquid component is made pasty, the invention makes it possible to achieve the mixing by a easy operation, whereby both of the first paste and the second paste are mixed with each other to achieve curing of the composition.
