Dental 4 Less, New imaging method could enable dentists to detect and heal tooth cavities much earlier
BELLINGHAM, Washington, USA, and CARDIFF, UK —Dental caries — tooth decay — is the most prevalent dental disease among children and adults around the world. Left too long before treatment, the disease results in difficulty eating, infection, and even tooth loss. Research published this week by SPIE, the international society for optics and photonics, in the Journal of Biomedical Optics describes a method enabling much earlier detection using inexpensive long-wavelength infrared imaging.
