Abstract

An aqueous dental glass ionomer composition comprising (A) a reactive particulate glass, (B) a water-soluble polymer comprising acidic groups, which is reactive with the particulate glass in a cement reaction, (C) a water-soluble, hydrolysis-stable monomer having a single polymerizable double bond and optionally a carboxylic acid group or hydroxyl group; (D) a water-soluble, hydrolysis-stable polymerizable crosslinker having at least two polymerizable carbon-carbon double bonds; and (E) a polymerization initiator system.
