Three t-amines, 4-(dimethylamino)benzoic acid (ABA), 4-(dimethylamino)benzaldehyde(MBA), 4-(dimethylamino)benzophenone (MBP), were investigated as new visible lightphotoinitiators for a dental resin composite of UDMA in order to improve photopolymerizationeffect. Three t-amines mixed with three photosensiizers, CQ, PD and DA, respectively. And thephotopolymerization effect of photoinitiators were compared with that of 4-(dimethylamino)ethyl methacrylate (AEM), the most widely used photoinitiator. Thephotopolymerization efficiency of UDMA containing the photoinitiator increased withirradiation time. The increase was in the order: MBP
