The aims of this book were to evaluate the color change of two Nano Hybrid resin composite materials (Omnichroma and Joyfil) following staining by coffee solution and bleaching by 30% Hydrogen Peroxide (In office bleaching) and compare between the results. Also to seek if there is any effect of these two procedures on the surface roughness of these two new Nano Hybrid resin composite restorations.
