Device for the recognition of caries, plaque or bacterial infection of teeth, the device having in substance a generator (4) for the generation of an excitation radiation (6) which with the aid of a dental handpiece (1) can be directed at a tooth (8) to be investigated, and a set of differently formed exchangeable emission and acquisition devices (2) for the irradiation of the tooth to be investigated with the excitation radiation (6) in dependence upon the surface of the tooth (8) to be treated in each case and for acquiring a fluorescence radiation (7) excited at the irradiated tooth (8). The individual exchangeable emission and acquisition devices (2) can each be removably coupled with the dental handpiece (1) and include a plurality of individual emission fibers (24a) and detection fibers (24b).

[ What is claimed is:] [1.] A device for detecting the presence of carries, plaque or bacterial infection on teeth, the device comprising:means for generating excitation radiation;a dental handpiece coupled to the generating means for receiving the excitation radiation therefrom and for directing said radiation away therefrom;a set of exchangeable light probe tips, each of the light probe tips being removably coupled with the dental handpiece for receiving the excitation radiation therefrom and for directing said radiation onto a region of a tooth, wherein fluorescence radiation is reflected by the tooth, and each of said light probe tips includes at least one individual emission fiber for receiving said excitation radiation from said dental handpiece and directing said excitation radiation onto said region of said tooth and a plurality of detection fibers for receiving said fluorescence radiation from said tooth and for conducting said fluorescence radiation to said dental handpiece, and wherein the light probe tip that is to be removably coupled with the dental handpiece is selected in dependence upon the surface property of the tooth region; andevaluation means coupled to the dental handpiece for receiving and evaluating the fluorescence radiation from the handpiece to identify carries, plaque or bacterial infection on said region of the tooth; and whereineach light probe tip (2) has at least one tube (25a, 25b, 25c) extending along the longitudinal direction of the light probe tip to stabilize the light probe tip.
