Abstract
The invention provides dental cement compositions and methods of using them for binding hard tooth material, metal and ceramic. The cement compositions include polymerizable acid reactive ethylenically unsaturated monomers, and a source of cations reactive therewith, to further crosslink the resulting polymer. The cements have superior adhesion to tooth without separately acid etching dentin or enamel. Compositions of are useful as dental luting cements, liners, bases and restoratives.
