      Evaluation of calculus imaging on root surfaces by spectral-domain optical coherence tomography
      Objective The aim of this in vitro study was to evaluate the ability of optical coherence tomography (OCT) to display calculus on root surfaces. Material and methods Ten teeth with calculus on the root surface were embedded in resin, omitting the root surface. A region of interest (ROI) was marked by small drill holes coronally and apically of the calculus and imaged by spectral-domain optical coherence tomography ([SD OCT], Telesto ...

      Analyzing the impact of glaucoma on the macular architecture using spectral-domain optical coherence tomography
      Purpose Using spectral domain optical coherence tomography (SD-OCT) the retina can be segmented automatically to visualize all retinal layers. In glaucoma chronically elevated intraocular pressure leads to a decline of retinal ganglion cells (RGC) which changes retinal architecture. The goal of these analyses was to gain insight into the changes induced by glaucoma within all macular layers using SD-OCT within a closely circumscribed glaucoma cohort. Materials and methods SD-OCT measurements ...

      Visualization of the pulp chamber roof and residual dentin thickness by spectral-domain optical coherence tomography in vitro
      The aim of this study was to evaluate the ability of spectral-domain optical coherence tomography (SD-OCT) to display the roof of the pulp chamber and to estimate the residual dentin thickness (RDT) of the pulp complex. The roots of 20 extracted human molars were embedded in epoxy resin, and crowns were longitudinally sectioned in the mesial-distal direction, exposing the pulp chamber. The coronal part of the crown was removed up ...

      Is Optical Coherence Tomography a Potential Tool to Evaluate Marginal Adaptation of Class III/IV Composite Restorations In Vivo?
      Objective: Margin analysis of Class III and IV composite restorations in vitro and in vivo occurred by scanning electron microscopy (SEM) and optical coherence tomography (OCT). The results were compared and related to clinical evaluation. Methods and Materials: Eight Class III composite restorations were imaged in vitro using OCT and SEM. The margins were analyzed quantitatively. OCT signals were verified by assignment to the criteria perfect margin, gap, and positive ...

      OCT for early quality evaluation of tooth–composite bond in clinical trials
      Objectives To evaluate early quality of composite restorations with a universal adhesive in different application modes clinically and with optical coherence tomography (OCT). Methods 22 patients with four non-carious cervical lesions each received composite restorations (Filtek Supreme TM XTE, 3 M). The universal adhesive Scotchbond Universal TM (SBU, 3 M) was applied with three etching protocols: self-etch (SE), selective-enamel-etch (SEE) and etch-and-rinse (ER). The etch-and-rinse adhesive OptiBond TM FL (OFL ...

      Optical coherence tomography to evaluate variance in the extent of carious lesions in depth
      Evaluation of variance in the extent of carious lesions in depth at smooth surfaces within the same ICDAS code group using optical coherence tomography (OCT) in vitro and in vivo. (1) Verification/validation of OCT to assess non-cavitated caries: 13 human molars with ICDAS code 2 at smooth surfaces were imaged using OCT and light microscopy. Regions of interest (ROI) were categorized according to the depth of carious lesions. Agreement ...

      Dental Applications of Optical Coherence Tomography (OCT) in Cariology
      Across all medical disciplines, therapeutic interventions are based on previously acquired diagnostic information. In cariology, which includes the detection and assessment of the disease caries and its lesions, as well as non-invasive to invasive treatment and caries prevention, visual inspection and radiology are routinely used as diagnostic tools. However, the specificity and sensitivity of these standard methods are still unsatisfactory and the detection of defects is often afflicted with a ...

      Optical Coherence Tomography to Evaluate Plaque Burden and Morphology in Patients With Takotsubo Syndrome
      ackground Disrupted atherosclerotic plaques in the left anterior descending coronary artery are discussed controversially as a potential pathophysiological mechanism in Takotsubo syndrome ( TTS ). Therefore, the aim of the present study was to assess plaque burden and morphology by using optical coherence tomography in patients with TTS . Methods and Results A total of 23 consecutive TTS patients were included in this single‐center study and underwent optical coherence tomography imaging of ...

      The Additional Diagnostic Value of Optical Coherence Tomography (OCT) and Its Application Procedure in A Wide Variety of Avian Species
      Objective : The current study introduced OCT as a novel tool in clinical veterinary ophthalmology in a much wider variety of free-living avian species than hitherto studied. Methods: OCT was tested and performed in 39 free-living birds (21 species of 12 families) and compared to direct ophthalmoscopy. Birds were examined with combinations of different restraints (manual restraint or fixation on a holding device) and different anaesthesia regimes (none, sedation, general anaesthesia ...

      Spatiotemporal closure of fractional laser-ablated channels imaged by optical coherence tomography and reflectance confocal microscopy
      Background and Objective Optical coherence tomography (OCT) and reflectance confocal microscopy (RCM) offer high-resolution optical imaging of the skin, which may provide benefit in the context of laser-assisted drug delivery. We aimed to characterize postoperative healing of ablative fractional laser (AFXL)-induced channels and dynamics in their spatiotemporal closure using in vivo OCT and RCM techniques. Study design/Materials and Methods The inner forearm of healthy subjects ( n =6) was ...

      Parametric Model for the 3D Reconstruction of Individual Fovea Shape from OCT Data
      As revealed by optical coherence tomography (OCT), the shape of the fovea may vary greatly among individuals. However, none of the hitherto available mathematical descriptions comprehensively reproduces all individual characteristics such as foveal depth, slope, naso-temporal asymmetry, and others. Here, a novel mathematical approach is presented to obtain a very accurate model of the complete 3D foveal surface of an individual, by utilizing recent developments in OCT. For this purpose ...

      Assessment of interfacial defects at composite restorations by swept source optical coherence tomography
      In clinical dental practice, it is often difficult or even impossible to detect and assess interfacial adhesive defects at adhesive restorations by means of visual inspection or other established diagnostic methods. However, nondestructive optical coherence tomography (OCT) may provide a better picture in this diagnostic scenario. The aim of this study was to evaluate the suitability of swept source OCT (SS-OCT) for the nondestructive assessment of interfacial deficiencies at composite ...
