Abstract

The present invention relates to a plaque detection device for the detection of plaque on a surface of a tooth. The plaque detection device comprises a mechanical probe including a probe tip being configured for moving along a surface of a tooth and comprising a first surface and a second surface, the first surface being configured for moving along the surface of the tooth, and the second surface being directed away from the surface of the tooth. The plaque detection device comprises further an optical sensor, the optical sensor being directed towards the second surface of the probe tip and configured for detecting light that is reflected and/or emitted from the second surface of the probe tip. The plaque detection device comprises further a processing unit, the processing unit being configured for receiving a signal of the optical sensor indicative of the light that is reflected and/or emitted from the second surface of the probe tip, and configured for determining a presence of plaque on the surface of the tooth based on a variation of the light that is reflected and/or from the second surface of the probe tip.
