Recently, the demand for a more natural and harmonious color of porcelain-fused-to-metal restoration is on the increase due to the recent rise in esthetic values among the patients. However, the usual methodology of shade taking, color transmission, and color evaluation is not soprecise. We have thus tried to resolve this problem with the aid of a computer color matching system for the purpose of reproducting the natural and harmonious color of rorcelain-fused-to-metal restoration. To obtain the colorimetric and optical fundamental data of dental porcelains, we analyzed its absorption and scattering coefficients by using a spectrophotometer. It was concluded that there was a high positive correlation between the absorption and scattering coefficient to porcelain thickness in both the dentin and enamel porcelain layers. As the wavelength increased, the absorption coefficient tended to decrease and the scattering coefficient tended to increase. From this experiment, it became possible to determine the absorption and scattering coefficient of the dentin and enamel porcelain layers of any shade and thickness.
