Dental restorative compositions of the composite resin/glass ionomer hybrid type and resins used in the compositions. The compositions contain an aromatic-moiety-containing polymerizable resin, a finely divided ion-leachable fluoroaluminosilicate glass filler, a polymerization initiator system, and may contain other components. The aromatic-moiety-containing polymerizable resin has at least one carboxylic acid group and at least one ethylenically unsaturated group such as a (meth)acrylate group. The compositions have improved mechanical strength, improved wear resistance, and sustained long-term fluoride release.
