ABSTRACT:
Dental cement containing water, acid-reactive filler, water-miscible acidic polymer, an ethylenically-unsaturated moiety, photoinitiator, water-soluble reducing agent and water-soluble oxidizing agent. The cement has three curing modes, namely an acid-filler ionic reaction, a photoinitiated crosslinking reaction and a redox-initiated crosslinking reaction. The cement cures well in thick layers, and can be used without a dental curing light or with a light that is weak or defective.
