A simple radiographic approach to maxillary pathologies.

This article describes an intraoral radiographic technique for identifying lesions located on the buccal surfaces of the maxillary alveolar process. An intraoral film is placed behind the maxillary tuberosity and the X-ray beam exposes the film perpendicularly, running laterally to the buccal surface of the cortical bone. As a result, any external alteration can be seen clearly, with no superimposed maxillary teeth or osseous tissues.
