Summary:The present application relates to an apparatus for imaging dental tissue using modulated photothermal radiometry and luminescence for inspection of dental tissues (120) of a patient, comprising at least one modulated laser light source (90, 92) for irradiating a portion of a surface of a dental tissue with a beam of light of an effective wavelength wherein modulated photothermal radiometric signals and modulated luminescence signals are responsively emitted from said portion of the dental surface. Further, the apparatus comprises an imaging detection means positioned with respect to said dental tissue for detecting images of said emitted modulated photothermal signals and said modulated luminescence signals, said imaging detection means (170) including a combined near infrared camera for detecting images of emitted modulated luminescence signals and a mid infrared camera for detecting images of said emitted modulated photothermal signals. In addition, the apparatus has demodulating means (106) for demodulati
