New imaging method could enable dentists to detect and heal tooth cavities much earlier

(SPIE--International Society for Optics and Photonics) Dental caries -- tooth decay --is one of the most prevalent oral diseases worldwide, but can be healed if detected early enough. While current diagnostic methods lack the sensitivity to detect early caries formation, researchers from York University in Toronto describe in the SPIE Journal of Biomedical Optics a new infrared imaging tool that can detect dental caries much sooner, while the progress of the cavity can be stopped or even reversed.
