    1. OCT partners with spectroscopy for better caries detection

      OCT partners with spectroscopy for better caries detection
      Optical coherence tomography (OCT) won't be commercially available to dentists until sometime next year, but researchers and commercial developers are already working to improve its ability to detect dental decay sooner and diagnose it more accurately. While OCT can probe more deeply into tissue than x-rays and thus help pinpoint where a suspected caries lesion is taking root -- plus quantify the extent of demineralization over time -- it cannot provide the biochemical information that would further enhance diagnostic specificity. So some researchers are combining OCT with another optical imaging technique: spectroscopy. Their goal is to leverage the strengths of both ...

    3. Nondestructive assessment of the inhibition of enamel demineralization by CO2 laser treatment using polarization sensitive optical coherence tomography

      Studies have shown that lasers can be used to modify the chemical composition of tooth enamel to render it less soluble. The purpose of this study was to determine if polarization-sensitive optical coherence tomography (PS-OCT) can be used to nondestructively assess the inhibition of demineralizatio ... [J. Biomed.

    4. Optical Coherence Tomography Imaging for Evaluating the Photobiomodulation Effects on Tissue Regeneration in Periodontal Tissue

      Optical Coherence Tomography (OCT) is a noninvasive method for imaging dental microstructure which has the potential of evaluating the health of periodontal tissue. OCT provides an “optical biopsy” of tissue 2–3 mm in depth. This sixth modality of imaging was pioneered at Lawrence Livermore National Laboratory. OCT is based on the optical scattering signatures within tissue structure. With the use of a broad spectrum bandwidth light source, high resolution images, up to 10 times the resolution of x-ray, can detect important tissue interfaces within the periodontal sulcus and its' relationship to the attachment apparatus of the tooth. Multiple cross-sectional ...

    10. Evaluation of crack propagation in dental composites by optical coherence tomography

      Evaluation of crack propagation in dental composites by optical coherence tomography
      Abstract Objectives The purpose of this study was to image the sites of fracture initiation and slow crack propagation in a fiber reinforced composite, using the optical coherence tomography (OCT) technique. Methods Bar specimens (2 mm × 3 mm × 25 mm) of fiber reinforced composite were mechanically and thermally cycled to emulate oral conditions. The interior of these samples was analyzed prior to and after loading, using OCT. The device used was a home-built Fourier domain OCT setup working at 800 nm with 6 μm spatial resolution. Results Intact specimens after load cycling were analyzed. It was clearly seen that OCT ...
