Methods The color of 3 kinds of imported composite resin was mearsured with the spectrophotonery system of human tooth color which had a fiber optic heading.The color range of imported composite resin was compared with that of Chinese teeth. Results The color distribution spaces of 3 kinds of imported compositeresin had different color ranges that were smaller than that of Chinese teeth. Being compared with Chinese teeth color, imported composite resin was short of higher and lower light color, and imported composite resin was short of greener and redder color either.
