Radiation-free OCT has been used in optometry for a while, but now, applications in dentistry are evolving, and you’ll be amazed at what this little toy can do. Because it produces two and three-dimensional images as detailed as a single micron and as deep as 3mm into tissue, OCT can help dentists:
â– Detect caries early
â– Assess for periodontal disease
â– Assess for oral cancer
â– Create digital impressions
â– Orthodontic treatment planning
■Endodontic imaging from inside a tooth’s canal
According to an article in Dental Products Report, Dr. Craig Gimble, Executive VP of Clinical Affairs for Lantis Laser, Inc., believes that optical coherence tomography will replace 70% of radiography in dentistry.
How it works… OCT scans gather cross-section images of hard and soft tissues by using fiber optics and photonics. De- and re-mineralization, tarter, and caries are identifiable and trackable, as is periodontal disease. For periodontal disease, OCT scans depict ligament detachment/reattachment and bone structure. Cellular changes are visible, as well, thus the OCT scan has acquired the nickname “optical biopsy.â€
