    3. Optical coherence tomography: fundamental principles, instrumental designs and biomedical applications

      Optical coherence tomography: fundamental principles, instrumental designs and biomedical applications
      The advances made in the last two decades in interference technologies, optical instrumentation, catheter technology, optical detectors, speed of data acquisition and processing as well as light sources have facilitated the transformation of optical coherence tomography from an optical method used mainly in research laboratories into a valuable tool applied in various areas of medicine and health sciences. This review paper highlights the place occupied by optical coherence tomography in ...

    4. A comparison of methods using optical coherence tomography to detect demineralized regions in teeth

      A comparison of methods using optical coherence tomography to detect demineralized regions in teeth
      Optical coherence tomography (OCT) is a three- dimensional optical imaging technique that can be used to identify areas of early caries formation in dental enamel. The OCT signal at 850 nm back-reflected from sound enamel is attenuated stronger than the signal back-reflected from demineralized regions. To quantify this observation, the OCT signal as a function of depth into the enamel (also known as the A-scan intensity), the histogram of the ...

    5. Detection and monitoring of changes in mineralized tissues or calcified deposits by optical coherence tomography and Raman spectroscopy

      Detection and monitoring of changes in mineralized tissues or calcified deposits by optical coherence tomography and Raman spectroscopy
      Early dental caries detection is carried out by a method that combines optical coherence tomography (OCT) and Raman spectroscopy to provide morphological information and biochemical specificity for detecting and characterizing incipient carious lesions found in extracted human teeth. OCT imaging of tooth samples demonstrated increased light back-scattering intensity at sites of carious lesions as compared to the sound enamel. Raman microspectroscopy and fibre-optic based Raman spectroscopy are used to characterize ...

    7. Early dental caries detection using a fibre-optic coupled polarization-resolved Raman spectroscopic system

      A new fibre-optic coupled polarization-resolved Raman spectroscopic system was developed for simultaneous collection of orthogonally polarized Raman spectra in a single measurement. An application of detecting incipient dental caries based on changes observed in Raman polarization anisotropy was ... [Opt. Express 16, 6274-6284 (2008)]
