Which x-ray unit is described as a panoramic dental radiography device?

• A. Panorex
• B. Hand held
• C. Intraoral
• D. Cephalometric

Answer: (A)

Panoramic imaging captures the entire arch of both jaws in one exposure by rotating the x-ray source and detector around the patient’s head, creating a single wide view of the teeth and surrounding structures. The Panorex is described as a panoramic dental radiography device because it uses that rotating mechanism to produce a broad image of the maxilla and mandible, often including the condyles and nearby areas. This differs from intraoral radiography, which uses small films or sensors placed inside the mouth to image individual teeth, not the full arch. Cephalometric radiography, on the other hand, provides a skull profile view (lateral or PA) for orthodontic analysis, not a panoramic view of the dentition. Hand-held units are portable and typically used for localized intraoral imaging rather than a full-arch panorama. So the device described as panoramic is the Panorex.
