Device for detecting caries, plaque or bacterial attack of the teeth
The identification system has a unit (4) for producing an excitation radiation (6). It is coupled to a dental handpiece (1) and is directed at a tooth (8) being tested. An emission and detector unit (2) radiates the tooth with the excitation beam and detects the fluorescence radiation (7) excited at the radiated tooth. The emission and detector unit (2) is coupled detachably with the dental handpiece. The individual fibres of the emission and detector unit are surrounded by a sleeve. This sleeve is made of metal or plastic. The emission and detector unit has at least one tube, running in a longitudinal direction.
