Pediatric Panoramic Radiography: Techniques, Artifacts, and Interpretation.

Abstract

Panoramic radiography, particularly in the pediatric population, is rarely addressed in the radiology literature. The authors provide an in-depth discussion of how these images are acquired, what artifacts can be visualized, and how to mitigate these artifacts. Dental anatomy, as well as relevant osseous and soft-tissue anatomy visible on a panoramic image, are reviewed. The appearance of the normal pediatric panoramic radiograph, with an emphasis on the dental follicle, is discussed, as well as how to differentiate this normal structure from underlying pathologic conditions. The most commonly encountered pathologic conditions of carious disease and trauma are emphasized. A systematic approach to diagnosing mass lesions and their appropriate work-up, including multimodality imaging examples of relevant pathologic conditions, is also provided. Finally, congenital anomalies, including some of the more commonly encountered dysplasias, are reviewed. The authors provide a concise review of the relevant information needed to confidently interpret a pediatric panoramic radiograph.
