Extraoral periapical radiography: an alternative approach to intraoral periapical radiography
It is difficult to take intraoral radiographs in some patients who are intolerable to place the film in their mouth. For these patients, Newman and Friedman recommended a new technique of extraoral film placement. Here we report various cases that diagnostic imaging was performed in patients using the extraoral periapical technique. This technique was used to obtain the radiographs for the pati...

متن کاملA Robust Algorithm for Automatic Registration of Intraoral Radiographs
Background Subtraction techniques enable precise quantiication of changes in dental tissue structure. Automatic subtraction of intra-oral radiographs acquired without individual adjustment aids requires a-posteriori correction of geometry and contrast diierences, i.e. registration. Methods Previous work has shown that perspective projection is a reliable model for sequential radiographs regardl...
