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