Novel Effective Photoinitiators for the Production of Dental Fillings

Photopolymerization is an environmentally-friendly, non-destructive, safe and solvent-free method. Moreover it guarantees low energy consumption. Therefore the photopolymerization is used in many scientific disciplines, including dentistry for production photocurable dental materials. In this work, the new photoinitiating systems based on camphoroquinone (CQ) and iodonium salts with tosyl anion for initiation of photopolymerization of the acrylates monomers bisphenol A - glycidyl methacrylate (BisGMA) and triethyleneglycol dimethacrylate (TEGDMA) was studied. As a reference, camphorquinone (CQ) and ethyl 4-(dimethylamino)benzoate (EDB) photoinitiating system was used.
