ABSTRACT:
The invention provides a dental glass ionomer cement composition comprising (a) an .alpha.-.beta. unsaturated carboxylic acid polymer having a weight-average molecular weight lying in a specific range, (b) a polymerizable unsaturated organic compound having a CH.sub.2 .dbd.C(R1)--COO group, (c) water, (d) an organic aromatic compound having a --SO.sub.2 group, (e) a fluoroaluminosilicate glass powder having a mean particle size and specific gravity each lying in a specific range and capable of reacting with the component (a), and (f) a compound containing at least one element selected from the group consisting of aluminum, iron and tin. This composition can be cured either without recourse to conventional redox reaction systems or without exposure to visible light. It can be used with good-enough physical properties for dental therapy while it is harmless to the dental pulp, and can be stored over an extended period of time.
