Periodontal Diseases Diagnosed Automatically Using Image Processing Techniques

Computer Engineering

Dental radiographs are an important tool for diagnosing periodontal disorders and assessing treatment outcomes. Radiography will become even more important in periodontal diagnosis as computer-based image acquisition and processing techniques improve. To identify periodontal diseases, Digital Subtraction Radiography (DSR) requires a pair of images with identical gray-level distribution and projection geometry. Without mechanical alignment of the patient, film, or x-ray source, a pair of identical images can be generated via DSR. The disadvantage of this technique is that if there is any mechanical alignment in the camera view, the outcome will be mismatched. This research describes a method for diagnosing periodontal disorders utilising a single radiographic X-ray image, eliminating the need for two scans..
