    Fried Illuminates the Future of Dentistry

    For anyone who dreads going to the dentist, there may be light at the end of the tunnel. Advances in laser and light-based imaging technologies may soon change the face of modern dentistry. Dr. Daniel Fried Tooth enamel is almost transparent at longer wavelengths, making it possible to shine near-infrared light on a tooth to detect dental decay. “You can see right into the tooth,” said Dr. Daniel Fried, professor, University of California, San Francisco School of Dentistry. “The enamel looks almost like an ice cube.” Light-based imaging is minimally invasive, providing a safer alternative to an X-ray’s ionizing ...

    1. You can see right into the tooth,” said Dr. Daniel Fried, professor, University of California, San Francisco School of Dentistry. “The enamel looks almost like an ice cube...Many lesions in the mouth have been re-mineralized and...no longer need inter­vention,” said Fried. “Dentists have trouble telling the difference between active and arrested lesions; this new technology has the potential of differentiating them.
    2. OCT [already] has changed the practice of ophthalmol­ogy...It’s been very successful for retinal imaging...and it’s also very promising for dentistry...If the dentist doesn’t know if [a lesion] is active or arrested,” said Fried, “with OCT, you can actually see the lesion struc­ture, how deep it is and if it has a definitive surface zone suggesting that remineralization has occurred.
