Abstract

Method and arrangement for evaluating a change (wear down), caused by treatment (brushing) of a treated tooth surface. A laser beam 3 is directed at the surface 4a, so that the beam 3a reflected by the surface is evaluated in a photocell layout 9, which in turn is connected to an electronic unit 11 for evaluation of the beam 3a received in the photocell layout 9. This evaluation is done before and/or during and/or after the treatment and a comparison of the result constitutes a measure of the change in the surface. <IMAGE>
