Summary:Computer color matching is an excellent method for reproducing certain colors of various objects using a spectrophotometer and a computer. In this study the authors attempted to reproduce the color of layered porcelain samples according to the computer color-matching formulation, wherein a computer color-matched sample is made and compared with the target sample. The color differences between the computer color-matched samples (opaque/dentin and opaque/dentin/enamel) and the target samples approximated 1.0, and the samples were indistinguishable by visual observation. The spectral reflectance curves were also very similar.
