    2. Non-destructive assessment of inhibition of demineralization in dental enamel irradiated by a = 9.3-µm CO2 laser at ablative irradiation intensities with PS-OCT

      Background and Objective: Polarization sensitive optical coherence tomography (PS-OCT) has great promise for the non-destructive assessment of the efficacy of anti-caries agents such as fluoride and thermal laser treatments on enamel surfaces. The purpose of this study was to demonstrate that PS-OCT can be used to measure demineralization in craters/incisions prepared in enamel by a CO2 laser operating at the high irradiation intensities required for cavity preparations. Materials and Methods Incisions in bovine enamel surfaces were produced by a CO2 laser used with a water spray. The laser was operated at = 9.3 µm with a pulse duration of ...

    5. Apparatus For Dental Oct Imaging (Wo 2008/063605)

      An apparatus (10) for obtaining an image of a tooth (20) includes an image sensor and a white light source (12) providing broadband polychromatic light and an ultraviolet light source providing narrow-band light. A combiner (15) directs broadband polychromatic light and narrow band light along a common illumination path to illuminate the tooth. A polarization beamsplitter (18) directs polarized light from the illumination path along an optical axis (216). An optical coherence tomography (OCT) imaging apparatus (70) splits the low coherence light into a sample path and a reference path and a dichroic element (78) directs the polarized illumination and ...

    6. Diagnosis of Vertical Root Fractures with Optical Coherence Tomography

      The purpose of this experiment was to evaluate the ability of optical coherence tomography (OCT) to image vertical root fractures (VRFs). Twenty-five mandibular premolars were prepared to size 50. Five teeth served as controls. Group 1 (n = 10) was treated with ethylenediaminetetraacetic acid and ultrasonic irrigation, whereas group 2 (n = 10) received no further treatments. Teeth from groups 1 and 2 were fractured, and the presence of a fracture line was demonstrated microscopically. Control group teeth were not subjected to any force. Teeth were pooled and scanned with an OCT fiber. The resulting video files were blindly interpreted by 2 ...

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

      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.

    9. Root canal filling evaluation using optical coherence tomography

      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.

    10. Investigation of bracket bonding for orthodontic treatments using en-face optical coherence tomography

      Cosmin Sinescu, Meda L. Negrutiu, Michael Hughes et al. Despite good diagnosis and treatment planning, orthodontic treatment can fail if bonding fails. It is now common practice to address the aesthetic appearance of patients using aesthetic brackets instead of metal ones. Therefore, bonding aesthetic brackets has become an issue for orthodontists today. ... [Proc. SPIE Int. Soc. Opt. Eng. 6991, 69911M (2008)] published Fri May 2, 2008.

      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.

      Optical coherence tomography imaging
      A digitized image of an object may include representations of portions of the object that are obscured, occluded or otherwise unobservable. The image may be a multi-dimensional visual representation of dentition. Characteristics of the dentition and its surfaces, contours, and shape may be determined and/or analyzed. A light may be directed toward and reflected from the dentition. The reflected light may be combined with a reference to determine characteristics of the dentition, including obscured areas such as subgingival tissue.
