摘要： 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.

摘要： A method, executed at least in part by a computer, acquires three- dimensional data from scans of maxillofacial and dental anatomy of a patient and computes cephalometric values from the acquired three-dimensional data. The method processes the computed cephalometric values and generates metrics indicative of tooth positioning along a dental arch of the patient. The generated metrics are analyzed to calculate desired movement vectors for individual teeth within the dental arch. The calculated desired movement vectors are displayed, stored, or transmitted.

摘要： An apparatus for obtaining an image of a tooth having at least one light source providing incident light having a first spectral range for obtaining a reflectance image (122) from the tooth and a second spectral range for exciting a fluorescence image (120) from the tooth. A polarizing beamsplitter (18) in the path of the incident light from both sources directs light having a first polarization state toward the tooth and directs light from the tooth having a second polarization state along a return path toward a sensor (68), wherein the second polarization state is orthogonal to the first polarization state. A first lens (22) in the return path directs image-bearing light from the tooth toward the sensor (68), and obtains image data from the portion of the light having the second polarization state. A long-pass filter (15) in the return path attenuates light in the second spectral range.

摘要： A method for intraoral imaging obtains a digital image of one or more teeth and detects first and second boundaries. At each of the first and second boundaries, there is calculated a boundary ratio of mean gray-scale values for the tooth area on one side of the boundary to mean gray-scale values for background areas on the other side. The calculated boundary ratios are stored. A third ratio of the mean gray-scale values for the tooth area near the first boundary to the mean gray-scale values for the tooth area near the second boundary is calculated and stored. A vector is formed and stored that contains at least the calculated boundary ratios and the third ratio. The tooth surface is classified as either smooth or occlusal according to the stored vector. The image data is processed according to the classification and processing results are reported.

摘要： An apparatus for imaging a tooth having a light source with a first spectral range and a second spectral range. A polarizing beamsplitter (18) light having a first polarization state toward the tooth and directs light from the tooth having a second polarization state along a return path toward a sensor (68), wherein the first and second polarization states are orthogonal. A first lens (22) in the return path directs image-bearing light from the tooth, through the polarizing beamsplitter (18), toward the sensor (68), and obtains image data from the redirected portion of the light having the second polarization state. A long-pass filter ( 15) in the return path attenuates light in the second spectral range. Control logic enables the sensor to obtain either the reflectance image or the fluorescence image.
