Accuracy of Kubelka-Munk reflectance theory for dental resin composite material

Corrected K-M reflectance theory may be used to accurately quantify the optical K-M absorption and scattering coefficients for contemporary dental resin composite materials, and this theory may be used to calculate accurately the reflectance spectrum for a clinically relevant thickness value and for a backing that is low, mid-range or high in lightness. Both color and translucency information of resin composite materials may be accurately predicted using corrected Kubelka-Munk reflectance model.
