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:

• Detect caries early
• Assess for periodontal disease
• Assess for oral cancer
• Create digital impressions
• 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.”

Dr. Gimble sees the future of OCT leading to more minimally invasive dentistry. OCT isn’t yet available, but Lantis is shooting for a 2011 launch of Lantis OCT Dental Imaging System™ , with FDA approval. The company has exclusive rights for OCT in dentistry, according to a Yahoo! Finance report.
