To investigate the influence of nanoscale inorganic content over optical and surface properties of model composites before and after ageing.Three model composites were formulated with silica fillers in nanoscale of 7nm (G1), 12nm (G2) and 16nm (G3), at 45.5% by weight in a matrix of BisGMA/TEGDMA 1:1. Color coordinates (CIE L*a*b* parameters), color difference (ΔE*), translucency parameter (TP), surface...
