Scanners that use digital imaging to analyze the shade of natural teeth and ceramic restorations. These scanners typically consist of a wand that includes an intraoral video camera, a spectrometer, software to process and store images, and a display. The units can record information such as hue, value, and chroma of teeth. Tooth shade scanners are used for matching the shade of a new restoration to the shade of the patient\'s teeth or existing restorations.
