Epub 2013 Dec 11.OBJECTIVES: To analyse the influence of irradiation time, aging before bleaching, and bleaching technique (home bleaching vs. in-office bleaching) on the amount of elutable substances from modern nano-hybrid resin-based composites (RBCs).METHODS: Specimens (n=5) of three nano-hybrid RBCs (Venus(®) Diamond, Tetric EvoCeram(®) and Filtek™ Supreme XTE) were irradiated for 5, 10, 20 and 40s. The degree of conversion (DC) was measured in real-time with Fourier transform infrared spectroscopy (FTIR). Read More
