A method and device for detecting dental caries, comprising means for exciting an area (12) of a tooth by pulses of monochromatic ultraviolet light alternating with pulses of visible light, video means (32, 34, 36, 38) for taking images of the fluorescence emitted by the tooth in two bands of high and low energy wavelengths respectively of the emission spectrum and of the information processing means (40) for making the report fluorescence spectral intensities in these two wavelength bands and deduce the presence or absence of caries in the area (12) examined of the tooth. |
