  Objectives In-vitro evaluation of the influence of preparation design and thickness of ceramic veneers on the interfacial bond using optical coherence tomography (OCT). Methods Sixty-four central incisors were randomly assigned to four preparation designs differing from no to complete dentine exposure (n = 16 each): non-prep (NP), minimal-invasive (MI, no dentine exposure), semi-invasive (SI, 50% dentine) and invasive (I, 100% dentine). Ceramic veneers (IPS InLine Veneer) of two thicknesses (0.20 ...

  Aims: The comparative efficacy of balloon-based techniques to prepare severely calcified coronary lesions before stenting remains poorly studied. We sought to compare stent expansion following preparation of severely calcified coronary lesions with either super high-pressure balloon or scoring balloon. Methods and results: In this randomized, open-label trial 74 patients with severely calcified coronary lesions were enrolled at 5 centers in Germany and Switzerland. After unsuccessful lesion preparation with standard non-compliant ...

4. An Intraoral OCT Probe to Enhanced Detection of Approximal Carious Lesions and Assessment of Restorations
  
  Explore MDPI Open Access Journals Platform Oct 13 2020 Dentistry
  
  Caries, the worlds most common chronic disease, remains a major cause of invasive restorative dental treatment. To take advantage of the diagnostic potential of optical coherence tomography (OCT) in contemporary dental prevention and treatment, an intraorally applicable spectral-domain OCT probe has been developed based on an OCT hand-held scanner equipped with a rigid 90-optics endoscope. The probe was verified in vitro. In vivo, all tooth surfaces could be imaged with ...

  Purpose To document with spectral-domain optical coherence tomography the structural stabilization of the fovea and the sealing of outer macular defects by Mller cells. Methods A retrospective case series of 45 eyes of 34 patients is described. Results In cases of a cystic disruption of the foveola as in macular telangiectasia type 2 and vitreomacular traction, the Mller cell cone provides the structural stability of the fovea. In cases of ...

7. Evaluation of calculus imaging on root surfaces by spectral-domain optical coherence tomography
  
  Explore ScienceDirect Jan 28 2019 Dentistry
  
  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 ...

8. Analyzing the impact of glaucoma on the macular architecture using spectral-domain optical coherence tomography
  
  Explore Journals | PLOS Jan 8 2019 Ophthalmology
  
  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 ...

  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 ...

10. Is Optical Coherence Tomography a Potential Tool to Evaluate Marginal Adaptation of Class III/IV Composite Restorations In Vivo?
  
  Explore Operative Dentistry Oct 16 2018 Dentistry
  
  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 ...

  Explore ScienceDirect Jun 23 2018 Dentistry
  
  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 ...

  Explore MDPI Open Access Journals Platform May 3 2017 Dentistry
  
  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 ...

  $Spatiotemporal closure of fractional laser-ablated channels imaged by optical coherence tomography and reflectance confocal microscopy$
  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 ...
