Abstract

|
|
Two diketones, 1-phenyl-1,2-propanedione(PD) and 2,3-butanedione (BD) were investigated asnew visible light photosensitizers for a dental resin composite of bis-GMA in order to improvephotopolymerization effect. And the photopolymerization efficiency of mixed photosensitizers,PD-CQ and DA-CQ, was studied. Photopolymerization effect of photosensitizers were comparedwith that of camphorquinone(CQ), the most widely used photosensitizer. The photopolymerizationefficiency of bis-GMA containing the photosensitizer increased with irradiation time. The increasewas in the order: BD < CQ < PD. The photopolymerization efficiency of this mixture was not soefficient as CQ or PD.
