Abstract

The aim of the present study was to determine the influence of the difference in color parameters on translucency of a ceramic material used for the fabrication of metal-ceramic restorations. Transparent porcelain was used with different concentrations of shaded porcelain to obtain disks with gradual changes in translucency. CIEL*a*b* parameters were recorded with a spectrophotometer and translucency parameter (TP) was calculated. ΔL* values were highly correlated with TP values. No significant correlation was found between TP and Δa*. Translucency was influenced by the changes in lightness and yellow–blue coordinate and disks that were more chromatic showed lower translucency values..
