    摘要: A contactless dental device 2 for determining tooth colors includes illuminating means for illuminating with ambient illumination light a tooth 6 to be examined. At least one color sensor 8 for acquisition and spectral examination of light reflected by the tooth 6 is inventively provided, wherein filtering means 16 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 18 for determining the tooth color based on the signal component originating from the illumination light are disposed downstream of the filtering means 16.

    摘要: A dental measuring device for three-dimensional measurement of a patient's teeth having projection means with a projection unit 8 to project a measuring structure onto a tooth to be examined. The device also has a camera to capture a measuring structure projected onto the tooth. According to the present invention, the projection unit has at least one UV light source, wherein the power output from the UV light source is selected or can be selected such that light-curing dental materials can be cured by the effect of the UV light, in such a way that the device can be used or is used for curing light-curing dental materials.
