Which anatomical regions are visible on panoramic radiographs?

• A. The maxilla, mandible, and surrounding anatomy.
• B. Only tooth crowns.
• C. Only temporomandibular joints.
• D. Only the alveolar bone.

Answer: (A)

Panoramic radiography is designed to capture a broad, single view of the facial skeleton, especially the jaws and surrounding structures. The technique uses a rotating x-ray tube and detector to produce a composite image that includes the maxilla, the mandible, the tooth crowns and roots, the alveolar bone, and nearby anatomy such as the nasal cavities, maxillary sinuses, zygomatic arches, and the temporomandibular joints. Because of this wide scope, the image shows more than just one small part; it reveals the maxilla, mandible, and surrounding anatomy in one exposure. That’s why it’s the best description of what panoramic radiographs show. The other options are too limited, as they refer to only specific structures (tooth crowns, only TMJs, or only alveolar bone) rather than the full panoramic view.
