METHODS AND SYSTEMS FOR ANALYZING HARD TISSUES

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, m...

Summary: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.
