    OCT partners with spectroscopy for better caries detection
    Optical coherence tomography (OCT) won't be commercially available to dentists until sometime next year, but researchers and commercial developers are already working to improve its ability to detect dental decay sooner and diagnose it more accurately. While OCT can probe more deeply into tissue than x-rays and thus help pinpoint where a suspected caries lesion is taking root -- plus quantify the extent of demineralization over time -- it cannot provide the biochemical information that would further enhance diagnostic specificity. So some researchers are combining OCT with another optical imaging technique: spectroscopy. Their goal is to leverage the strengths of both ...
