ABSTRACT:
The invention provides dental composite compositions formed by mixing a curable liquid composition with a powder in preselected proportions. The composite compositions formed are useful as cement, liner, base, restorative, pit and fissure sealants, and/or core build-up material, etc. having improved adhesion to dentin. These composite compositions include polyalkenoic acid, filler which provides elutable cations which are reactive with the polyalkenoic acid and fluoride ion, water to provide for elution of cations reactive with polyalkenoic acid, polymerizable monomer and/or prepolymer composition, unsaturated organic acid having 1 or more polymerizable groups and a catalyst system for polymerization. Optionally the composites include inert reinforcing filler for strength, aesthetics, and radiopacity.
