Radiopacities in Periapical and Panoramic Radiographs

Abstract

Both periapical and panoramic radiographies are routinely used in the daily dental practice. They may accidentally reveal abnormal radiopacities. However, clinicians may overlook or misdiagnose these radiopacities more frequently than abnormal radiolucensies. In this paper, common radiopaque lesions including periapical focal radiopacities and tonsilloliths were introduced. These imaging characteristics and clue to differential diagnosis were also described.
