Which statement best describes a panoramic radiography technique?

• A. An intraoral technique focusing on a single tooth.
• B. An extraoral technique that images the entire dentition, jaws, and surrounding structures in one arc; shows maxilla, mandible, and surrounding anatomy.
• C. A technique that only images the alveolar ridges.
• D. A method that uses CT-like three-dimensional data.

Answer: (B)

Panoramic radiography provides a broad, single-image view of the maxillofacial region. It is an extraoral technique where the x-ray source and detector rotate around the patient’s head to capture a two-dimensional image of the entire dentition, both jaws, and the surrounding structures in one arc. This setup yields a comprehensive view of the upper and lower arches, the teeth, and adjacent anatomy, which is why the statement describing an extraoral technique that images the whole dentition and jaws in one arc, showing maxilla, mandible, and surrounding anatomy, is the best fit.

This differs from intraoral techniques, which focus on a small area or a single tooth with the film inside the mouth. It also isn’t limited to imaging only the alveolar ridges, and it doesn’t provide three-dimensional, CT-like data.
