Abstract
The invention can be used to determine the color to be given to a dental prosthesis, for example, on the basis of color measurements performed on adjacent teeth in the mouth of the patient. An optical fiber instrument picks up light reflected from a tooth and transmits it to the inlet of a spectrocolorimeter which associated with a microprocessor in order to determine the diffuse spectral reflectance of the tooth and to calculate the tristimulus values of its apparent color under various different types of illumination. The invention is particularly suitable for determining the color of dental prostheses.
