Abstract
A contactless dental device for determining tooth colors includes illuminating means for illuminating with ambient illumination light a tooth to be examined. At least one color sensor for acquisition and spectral examination of light reflected by the tooth is inventively provided, wherein filtering means are associated with the color sensor for at least partial separation of a signal component originating from the illumination light from the signal component originating from the ambient light. Evaluating means for determining the tooth color based on the signal component originating from the illumination light are disposed downstream of the filtering means.
