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