    2. In vitro longitudinal evaluation of enamel wear by cross-polarization optical coherence tomography

      In vitro longitudinal evaluation of enamel wear by cross-polarization optical coherence tomography
      Objectives Enamel thickness determination by Cross-Polarization Optical Coherence Tomography (CP-OCT) is a promising approach for quantitative monitoring of tooth wear progression. This study evaluated the ability of CP-OCT to quantify the thickness of natural enamel before, during and after tooth wear simulation. Materials and Methods Natural, unpolished human dental enamel slabs were submitted to five wear stages (Wear 1: to level the surfaces; Wear 2 to Wear 5: 0.05 ...

      Fried Illuminates the Future of Dentistry
      For anyone who dreads going to the dentist, there may be light at the end of the tunnel. Advances in laser and light-based imaging technologies may soon change the face of modern dentistry. Dr. Daniel Fried Tooth enamel is almost transparent at longer wavelengths, making it possible to shine near-infrared light on a tooth to detect dental decay. You can see right into the tooth, said Dr. Daniel Fried, professor ...

    9. CORRELATION OF EN FACE OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY AVERAGING VERSUS SINGLE-IMAGE QUANTITATIVE MEASUREMENTS WITH RETINAL VEIN OCCLUSION VISUAL OUTCOMES

      CORRELATION OF EN FACE OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY AVERAGING VERSUS SINGLE-IMAGE QUANTITATIVE MEASUREMENTS WITH RETINAL VEIN OCCLUSION VISUAL OUTCOMES
      Purpose: To demonstrate the effect of averaging multiple en face optical coherence tomography angiography images on the correlation between retinal microvasculature quantitative metrics and best-corrected visual acuity (BCVA) in eyes with retinal vein occlusion . Methods: A cross-sectional cohort with unilateral retinal vein occlusion was imaged in both eyes. Five 3 mm 3-mm spectral domain optical coherence tomography angiography images were averaged, and quantitative parameters from averaged versus single images were ...

    10. Evaluation of Corneal Epithelial Thickness Imaged by the High Definition Optical Coherence Tomography in Healthy Eyes

      Evaluation of Corneal Epithelial Thickness Imaged by the High Definition Optical Coherence Tomography in Healthy Eyes
      Purpose: To evaluate corneal epithelial thickness (CET) and corneal thickness (CT) in healthy eyes using spectral domain optical coherence tomography. Methods: Thirty-six healthy eyes were imaged using the Cirrus high-definition (HD)-optical coherence tomography device. The average CET and CT were assessed using Cirrus Review Software within predefined concentric corneal ring-shaped zones. Specific regions of CET (superior, inferior, temporal, nasal, superonasal, inferotemporal, superotemporal, and inferonasal) were also assessed. The difference ...

    12. Aging-associated changes in cerebral vasculature and blood flow as determined by quantitative optical coherence tomography angiography

      Aging-associated changes in cerebral vasculature and blood flow as determined by quantitative optical coherence tomography angiography
      Capillary velocity increases by 21% and velocity heterogeneity increases by 19% with older age. Abstract Normal aging is associated with significant alterations in brains vascular structure and function, which can lead to compromised cerebral circulation and increased risk of neurodegeneration. The in vivo examination of cerebral blood flow (CBF), including capillary beds, in aging brains with sufficient spatial detail remains challenging with current imaging modalities. In the present study, we ...

    13. Use of Optical Clearing Agents for Imaging Root Surfaces With Optical Coherence Tomography

      Use of Optical Clearing Agents for Imaging Root Surfaces With Optical Coherence Tomography
      The diagnosis of root caries and root fractures is of increasing importance due to our aging population. The objective of this study is to show that optical clearing agents can be used to increase the visibility of subsurface structures in tooth roots to aid in the diagnosis of root caries depth and extension and to differentiate from subsurface defects. Previous studies have shown that high refractive index fluids can increase ...
