    Abstract: A method for obtaining an image of tooth tissue directs incident light toward a tooth (20), wherein the incident light excites a fluorescent emission from the tooth tissue. Fluorescence image data (50) is obtained from the fluorescent emission. Back-scattered reflectance image data (52) is obtained from back-scattered light from the tooth tissue. The fluorescence and back-scattered reflectance image data are combined to form an enhanced image (64) of the tooth tissue for caries detection.

    Abstract: A method for caries detection uses an image capture device (30, 32) to obtain fluorescence image data from the tooth (20) by illuminating the tooth to excite fluorescent emission. A first enhanced image of the tooth is then obtained by illuminating the tooth at a first incident angle, obtaining a back-scattered reflectance image data from the tooth tissue, and combining the back-scattered reflectance image data with the fluorescence image data. A second enhanced image of the tooth is then obtained by illuminating the tooth at a second incident angle, obtaining a back-scattered reflectance image data from the tooth tissue, and combining the back-scattered reflectance image data with the fluorescence image data. The first and second enhanced images are then analyzed to select and display the best-contrast image. This method provides high contrast images for carious regions (58) on all tooth surfaces.
