Abstract
A method for caries detection uses an image capture device () to obtain fluorescence image data from the tooth () 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 () on all tooth surfaces.
