Photobleaching of camphorquinone during polymerization of dimethacrylate-based resins.
Dent Mater
December 2009
Instituto de Investigación en Ciencia y Tecnología de Materiales, Mar del Plata University - National Research Council (CONICET), Av. Juan B. Justo 4302, 7600 Mar del Plata, Argentina.
Objective: The aim of this study was to compare the photobleaching rate of CQ in different dental resins.
Methods: The photodecomposition rate of CQ/amine system in bis-GMA/TEGDMA, bis-EMA and UDMA polymerizing monomers was evaluated at different light intensities. The photobleaching of the CQ was studied by monitoring the decrease in light absorption as a function of continuous irradiation time.
