Abstract. A colorimetric device for measuring the color parameters of tooth enamel in normal and erosive state in therapeutic dentistry is developed. A block diagram of the colorimeter and the graphic representation of spectral sensitivity of the receiving part of the device are presented. Metrological capabilities of the developed colorimeter are analyzed with the use of results of measurement by a certified device. Results of carried out calibration of the colorimetric device and the data of test measurements of chromaticity coordinates of certified and cataloged glass show that the colorimeter can be used to control diffusely reflecting objects. In particular, the device can be used in therapeutic dentistry to examine in vivo human tooth enamel in various states. Characteristics of the test samples were determined near marked points to confirm the results authenticity.
