To assess the effect of silver nano-particles on the color of dental porcelain, optical properties were analyzed based on CIELAB color coordinates L^*, a^* and b^*. The porcelain disks including silver nano-particles up to 1000ppm were fired and polished. Spectral reflectance data were collected using a spectrophotometer, and color coordinates were determined using UV probe color software. The mean ΔE^* value significantly increased as the content of silver nano-particles, however, the color differences for those including up to 200ppm were below the threshold for clinical color perceptibility.
