摘要: The aim of this study was to investigate the extent polymerization (Ep) in terms rate UDMA/TEGDMA resin mixtures and its composite resin, by using a differential scanning calorimeter (DSC) technique employing photopolymerization apparatus. used consisted urethane dimethacrylate (UDMA) as base monomer triethyleneglycol (TEGDMA) low viscosity monomer. concentration TEGDMA mixed varied 0, 20, 40, 60, 80, 100 mol %. Additionally, consisting 60 % UDMA 40 TEGDMA, four kinds composites with silica filler 70 wt %, were prepared study. general reaction profile Ep values obtained from DSC curves. Increasing resulted decrease mixture, delay time maximum rate, an increase mixtures. Furthermore, decreased increasing content between 0 but did not further
