  • Method and apparatus for periodontal diagnosis
    Patent number: 8738116
    Abstract: A technique for obtaining information regarding a state of periodontal tissue involves deriving a substantially whole curve measure of similarity of an observed bandshape of an isolated spectral component attributed to water within the infrared region. Subtle variations in the bandshape of the water bands have been found to correlate with inflammatory periodontal diseases and using whole curve measures such as weighted integrals or measure of fit parameters these variations can be detected and used to classify periodontal tissues.
    Type: Grant
    Filed: September 22, 2008
    Date of Patent: May 27, 2014
    Assignee: National Research Council of Canada
