[Effects of shade of visible light cured composites on their polymerization]
Conversion degree of double bonds,microhardness and cure depth of different shade of two visible light cured composites were inspected by means of the Fourier transform infrared spectroscopy and other techniques.The results showed that polymerization in the deep of visible light cured composites was significantly affected by shade of resins.The cure uniformity and the cure depth of darker resins were lower than those of lighter ones.
