Abstract
The color of laminate veneer crown is affected strongly by underlying cements. Therefore, if color of the mixed resin cements can be predicted, color resin cement is efficient to adjust the color of laminate veneer crown. The purpose of this study was to establish color prediction of cement mixtures based on the Kubelka-Munk theory. Absorption and scattering coefficients of monotone-opaque (OP), -light (L), -red (R), and -blue (B) shades were measured with white and black backings using a spectrophotometer (CASID 1). Then, reflectivity (R∞) of 1: 1 mixtures of OP+L, OP+B, and OP+R were predicted from the calculated coefficients of respective monotone values. These predicted values were compared with R∞ calculated from measured absorption and scattering coefficients of the mixed resin samples. The color differences (dE) between the predicted R∞ and measured R∞ were very small, and can not be clinically discriminated. In conclusion, precise prediction of mixed color resin cement was achieved. The color prediction of the cement is considered to be effective for color adjustment of laminate veneer crowns.
