The influence of different thicknesses of dentin porcelain on the color reflected from thin opaque porcelain fused to metal.
Gold and nickel-chromium alloys were used as substrates for one shade of fused porcelain. Chroma characteristics were compared between samples with opaque thicknesses of 0.1, 0.2, and 0.3 mm. Thicknesses of 0.1 to 0.5 mm of dentin porcelain fused on each of the thicknesses of opaque porcelain were measured. Perceptible color differences were found for most of the samples, and all nongold alloy samples showed such changes.
