    2. Fixed partial dentures investigated by optical coherent tomography

      Cosmin Sinescu, Meda Negrutiu, Carmen Todea et al. Fixed partial prostheses as integral ceramics, integral polymers, metal ceramics or metal polymers bridges, are mainly used in the frontal part of the dental arch (especially the integral bridges). They have to satisfy high stress requirements as well as esthetic. The masticatory stress may induce f ... [Proc. SPIE Int. Soc. Opt. Eng. 6847, 684707 (2008)] published Mon Feb 18, 2008.

    3. Imaging of hard- and soft-tissue structure in the oral cavity by optical coherence tomography.

      Imaging of hard- and soft-tissue structure in the oral cavity by optical coherence tomography. Appl Opt. 1998 Jun 1;37(16):3582-5 Authors: Colston BW, Everett MJ, Da Silva LB, Otis LL, Stroeve P, Nathel H We have developed a prototype optical coherence tomography (OCT) system for the imaging of hard and soft tissue in the oral cavity. High-resolution images of in vitro porcine periodontal tissues have been obtained with this system. The images clearly show the enamel-cementum and the gingiva-tooth interfaces, indicating OCT is a potentially useful technique for diagnosis of periodontal diseases. To our knowledge, this is the ...

    4. Optical coherence tomography imaging for evaluating the photo biomodulation effects on tissue regeneration in the oral cavity

      Craig B. Gimbel Optical Coherence Tomography (OCT) is a noninvasive method for imaging dental microstructure which has the potential of evaluating the health of periodontal tissue. OCT provides an "optical biopsy" of tissue 2-3 mm in depth. Optical biopsy is a measurement of the localized optical properties based o ... [Proc. SPIE Int. Soc. Opt.

      G. van Soest, H. Shemesh, M.-K. Wu et al. In root canal therapy, complications frequently arise as a result of root fracture or imperfect cleaning of fins and invaginations. To date, there is no imaging method for nondestructive in vivo evaluation of the condition of the root canal, during or after treatment. There is a clinical need for a ... [Proc. SPIE Int. Soc. Opt.

    11. Optical approach for monitoring the periodontal ligament changes induced by orthodontic forces around maxillary anterior teeth of white rats

      Optical approach for monitoring the periodontal ligament changes induced by orthodontic forces around maxillary anterior teeth of white rats
      Abstract  Structural variations of the periodontal ligament (PDL) induced by orthodontic forces have been evaluated by optical coherence tomography (OCT) and compared to images obtained by conventional radiography. Here, two specially designed orthodontic appliances were installed on the maxillary anterior teeth of white rats for applying different magnitudes of orthodontic forces. Constant distraction force magnitudes of 0, 5, 10, and 30 gf were given to four respective rats over a period of 5 days. At the end of the treatment period, the rats were sacrificed and the maxillaries were extracted for X-ray and OCT imaging. The PDL variations, proportional to ...

      The end of dental x-rays
      DENTISTS FINALLY have an alternative to the x-ray, and it offers up to 10 times the resolution with none of the radiation. The OCT is the first handheld scanner that can simultaneously image both your teeth and gums. When the near-infrared beam shines into the mouth, software maps the reflected light and forms a 3-D picture, revealing cavities, gum disease, surface irregularities and other signs of tooth decay. lantislaser.com

    13. Lantis Laser Podcast

      The company’s product launch will occur in September 2008 but the buzz about their OCT product is spreading. OCT stands for Optical Coherence Tomography, a light-based diagnostic imaging system. The system claims that it shows ten times more resolution than traditional radiographs. Since it does not use radiation, it is safe for use on pregnant patients. Popular Science magazine recently named Lantis Laser as one of its Best of What’s New in 2007 award recipients. Click here
