Semi-automatic computer aided lesion detection in dental X-rays using variational level set

The diagnosis of many dental anomalies would be impossible without radiographs, because of their location in the mineralized tissues (bone and teeth) or because they are hidden under the surface of the cortical plate that cannot be seen during a visual examination in dental practices. The use of radiographs is indispensable during the treatment phase, e.g., during root canal treatment to monitor the progress of the root preparation, or to know the orientation of wisdom molars to be extracted. The effect of dental treatment of bony structures, e.g., the treatment of periodontal defects or the success of an apicoectomy can be established by radiographic examination only.
