Abstract
A paste type dental glass ionomer cement composition in paste type using no polymerizable monomer, that is good in operationality with excellent inherent characteristics of glass ionomer cement maintained, is constituted with a first paste and a second paste, in which the first paste contains 30 to 70% by weight of a polymer of an α-β unsaturated carboxylic acid and 30 to 70% by weight of water, and the second paste contains 50 to 85% by weight of fluoroaluminosilicate glass, 0.005 to 1% by weight of a water soluble thickening agent and the remaining percentage by weight of water, the mixing amount of the water soluble thickening agent being preferably 0.01 to 0.4% by weight.
