  • Methods and products for analyzing gingival tissues
    Patent number: 8073212
    Abstract: A system and method employing image analysis may provide an objective measure of the state of gingival tissue health. A region of analysis on an image of gingival tissue may be divided into pixels. Each pixel may have an associated color made up of component R, G and B values. A user may obtain an objective measurement of oral cavity soft tissue health by determining an objective measurement of the component color values of a gingival tissue image region and performing statistical analysis on the color values.
    Type: Grant
    Filed: July 25, 2007
    Date of Patent: December 6, 2011
    Assignee: The Procter & Gamble Company
    Inventors: Robert Woodrow Gerlach, Roger David Gibb, Michael Eugene Rubush, John Michael Dunavent, Stephen Francis McClanahan
  • METHODS AND SYSTEMS FOR ANALYZING HARD TISSUES
    Publication number: 20110058717
    Abstract: A method and system employing image analysis may provide an objective measure of property values related to hard tissue or teeth in the oral cavity. A region of analysis on an image of hard tissue may be divided into pixels. Each pixel may have an associated color characteristic (e.g., R, G and B, multispectral) which is used to quantify a hard tissue property value of interest (e.g., percent plaque coverage, L*a*b* tooth color, percent stain). Hard Tissues Regions of Interest may be divided into indexed registration cells that allow for combining and/or comparing property values between images on a localized cell-by-cell basis. Results of cell-level property value analyses may be displayed by color-coding hard tissue pixels of a display image.
