The need to document the stage of determination of color, transfer color information for the dental technical laboratory, quality control of completed restoration necessitate the introduction of new technologies and devices in dental practice. We have considered various options for determining the color of teeth and restorations and a visual colorimetric method: there were formed 4 groups of patients. In the 1st group color of teeth and restorations doctor and dental technician were determined by the visual method, in the 2nd group doctor determines the color of the teeth and restorations and a visual colorimetric method and visual techniques only, in the 3rd group doctor and dental technician color was determined by visual and colorimetric method, and 4-th group of the doctor and the dental technician relied on the performance of the spectrophotometer and did not take into account visual sensations. Optimal results were obtained in группе2 where the doctor combined hardware and visual method of determining the color and in group 3, where both the doctor and the dental technician used hardware and visual methods of color determination. In the result of the study recommendations for carrying out colorimetric determination of color in the dental practice, recommendations are given to assess the performance of the spectrophotometer and interpretation of its parameters.
