    2. Optical coherence tomography combined with confocal microscopy for investigation of interfaces in class V cavities

      Standardized class V cavities, prepared in human extracted teeth, were filled with Premise (Kerr) composite. The specimens were thermo cycled. The interfaces were examined using a system employing two simultaneous imaging channels, an en-face Optical Coherence Tomography channel and a confocal microscopy channel.

    3. Dual optical coherence tomography/fluorescence microscopy for monitoring of Drosophila melanogaster larval heart

      This article demonstrates a combined instrument of two imaging modalities to acquire information on cardiac function in larval Drosophila melanogaster: optical coherence tomography (OCT) and laser scanning fluorescence microscopy (LSFM). For this purpose, a dedicated imaging instrument able to sequentially provide cross-sectional OCT and C-scan LSFM images has been developed. With this dual-imaging system, the heart can be easily located and visualized within the specimen and the change of the ...

    4. Simplified dynamic focus method for time domain OCT

      A new optical arrangement for performing dynamic focus in time domain optical coherence tomography (OCT) is demonstrated. Unlike previously reported schemes which require mechanical coupling of the object and reference arms, this method is confined to the object arm only and therefore does not impose design constraints on the OCT system layout. The scheme is tested on a high lateral resolution OCT system (NA = 0.13) and it is shown ...

    5. En face optical coherence tomography investigation of apical microleakage after laser-assisted endodontic treatment

      The aim of our study was to evaluate the potential of en face optical coherence tomography (OCT) for the detection of apical microleakage after 980 nm and 1,064 nm laser-assisted endodontic treatment. Ninety, human, single-rooted teeth with one straight root canal and closed apices were used. All roots were prepared biomechanically to the working length at an apical size 30 and 0.06 taper. The teeth were divided into ...

    6. Optical coherence tomography and confocal microscopy investigations of dental structures and restoration materials

      Nowadays, optical tomographic techniques are of particular importance in the medical imaging field, because these techniques can provide non-invasive diagnostic images. The present study evaluates the potential of en-face optical coherence tomography (OCT) as a possible non-invasive high resolution imaging method in supplying the necessary information on the quality of dental hard tissues and defects of dental restorative materials. Teeth after several treatment methods are imaged in order to asses ...

    7. Effect of masticatory load on cracks deflection/penetration investigated with en-face optical coherence tomography in ceramic fixed partial dentures

      Optical Coherence Tomography (OCT) allows a better characterization of dental prostheses. The detection of substance defects within the ceramic layers for metal-ceramic prostheses was demonstrated. The detected defects have a large volume and therefore there is a high likelihood for fracture lines to be generated in the proximal areas of the ceramic fixed partial dentures. If the detection of such defects is feasible before inserting the prosthesis into the oral ...

  2. About Adrian G. Podoleanu

    Adrian G. Podoleanu

    Adrian G. Podoleanu is the head of Applied Optics Group and Professor of Biomedical Optics at the University of Kent at Canterbury. Adrian Podoleanu has joined the Applied Optics Group in January 1993 as a Tempus Fellow and then worked as a Research Associate since Sept. 1993. Up to 1992, he was associate professor in the Technical University Bucharest, Romania, where he taught Physics, Optics and optoelectronics and developed research on Lasers and fast optoelectronics. He was involved in Kent in research and development of a subnanosecond dwell time multichannel digital correlator (the fastest multichannel configuration), in distance measurements using white light interferometry, Faraday sensing and secure optical communications. Since 1995 he is been working in the optical coherence tomography (OCT) field for imaging eye and skin and flow characterisation. He contributed towards development of the en-face OCT imaging as a new technology to complement the more conventional longitudinal OCT imaging. For the first time, he generated dual OCT and confocal images of the retina. He is co-author of more than 150 journal papers and conference proceedings and of 13 patents on the above mentioned subjects. In 1984, he was awarded The Romanian Academy "Constantin Miculescu" prize for research in Lasers and Nonlinear Optics.
