  1. Quality assessment of dental treatments using en-face optical coherence tomography

    Explore Article SPIE Digital Library (Oct 6 2008) Dentistry

    Cosmin Sinescu, Meda Lavinia Negrutiu, Carmen Todea et al. The present study evaluates the potential of en-face optical coherence tomography (OCT) as a possible noninvasive high resolution method for supplying necessary information on the material defects of dental prostheses and microleakage at prosthetic interfaces. Teeth are also imaged after several tre ... [J. Biomed. Opt. 13, 054065 (2008)] published Mon Oct 6, 2008. (Read Full Article)

  3. Quasi-simultaneous optical coherence tomography and confocal imaging

    Explore Article SPIE Digital Library (Jul 18 2008) Microscopy , Ophthalmology

    Irina Trifanov, Michael Hughes, Adrian Gh. Podoleanu et al. A new approach of acquiring quasi-simultaneous optical coherence tomography (OCT) and confocal images is presented. The two images are generated using different principles, OCT and confocal microscopy. When the system is used to image the retina, the two images have depth resolutions, at present, of ... [J.

  4. Fibres reinforced dentures investigated with en-face optical coherence tomography

    Explore Article SPIE Digital Library (May 2 2008) Dentistry

    Meda L. Negrutiu, Cosmin Sinescu, Michael Hughes et al. The complete dentures are currently made using different technologies. In order to avoid deficiencies of the prostheses made using the classical technique, several alternative procedures have been devised. In order to enhance the mechanical strength, complete denture bases are reinforced with fibres ... [Proc. SPIE Int. Soc. Opt. Eng. 6991, 69911U (2008)] published Fri May 2, 2008. (Read Full Article)

  5. Root canal filling evaluation using optical coherence tomography

    Explore Article SPIE Digital Library (May 2 2008) Dentistry

    Meda L. Negrutiu, Cosmin Sinescu, Michael Hughes et al. The root canal fillings are destined to seal the root canal especially in the apical areea. Invasive techniques are known which are used to assess the quality of the seal. These lead to the destruction of the probes and often no conclusion could be drawn in respect to the existence of any microleaka ... [Proc. SPIE Int. Soc. Opt. Eng. 6991, ... (Read Full Article)

  6. An optical coherence tomography investigation of materials defects in ceramic fixed partial dental prostheses

    Explore Article SPIE Digital Library (May 2 2008) Dentistry

    Cosmin Sinescu, Meda Negrutiu, Michael Hughes et al. Metal ceramic and integral ceramic fixed partial prostheses are mainly used in the frontal part of the dental arch because for esthetics reasons. The masticatory stress may induce fractures of the bridges. There are several factors that are associated with the stress state created in ceramic restora ... [Proc. SPIE Int. Soc. Opt. Eng. 6991, 69910O (2008)] published Fri May 2, 2008. (Read Full Article)
