摘要:
There is provided a high-spatial-resolution dynamic diagnostic instrument whichcan provide simultaneous measurements of laser-induced frequency-domain infraredphotothermal radiometric and alternating-current (ac) modulated luminescencesignals from defects, demineralization, remineralization and caries in teethintraorally. The emphasis is on the abilities of this instrument to approachimportant problems such as the detection, diagnosis and ongoing monitoringof carious lesions and or defects on the occlusal pits and fissures, smooth surfacesand interproximal areas between teeth which normally go undetected by x-rayradiographs or visual examination. The instrument is also able to detect earlyareas of demineralized tooth and or areas of remineralized tooth as well as defectsalong the margins of restorations. This capability of inspecting a local spotcan be extended to a modulated imaging of sub-surface of target tooth by usinga multi-array infrared camera. Two configurations of the instrument are presented.
