ABSTRACT:
A curable dental composition comprising an ethylenically unsaturated moiety, an oxidizing agent and metal complexed ascorbic acid is claimed. The incorporation of metal complexed ascorbic acid provides a curable composition that exhibits improved color stability. The metal complexed ascorbic acid is particularly useful as a component of a paste:paste glass ionomer dental cement.
