Abstract
Method and device for the recognition of caries, plaque, concretions or bacterial infections on teeth, whereby with the aid of a light source (1) an excitation radiation (9) is generated which is directed at a tooth (4) to be investigated and there brings about a fluorescence radiation (10). The fluorescence radiation is detected and evaluated with a detection device (8). A spectral filter is arranged before the detection device (8) which restricts the fluorescence radiation detected and evaluated by the detection device (8) to wavelengths greater than ca. 800 nm, in order to make possible an improved detection of carious tooth regions. Advantageously, the irradiation of the tooth to be investigated is effected with a relatively long wavelength excitation radiation (9), the wavelength of which may be for example ca. 780 nm.
