Which projection is commonly used to obtain a broad view of the jaws and surrounding structures?

• A. Panoramic radiograph
• B. Bitewing radiograph
• C. Occlusal radiograph
• D. Periapical radiograph

Answer: (A)

A single broad-view image of the jaws is captured with a panoramic radiograph. This technique uses a rotating X-ray source and film (or sensor) around the head to produce one wide image that includes both jaws, the temporomandibular joints, and nearby structures like the maxillary sinuses and nasal area. Because it encompasses the entire dentomaxillofacial region in a single exposure, it’s ideal for surveying anatomy, planning orthodontic treatment, evaluating trauma, detecting large lesions, and assessing overall relationships between teeth and supporting structures. Bitewing radiographs focus on the crowns and interproximal areas of posterior teeth, showing bone level changes between adjacent teeth but not the whole jaw. Occlusal radiographs provide broader views of a portion of an arch or the floor of the mouth or palate, but they don’t cover the full dentition and surrounding structures like a panoramic image. Periapical radiographs target the apex area of a few teeth and their surrounding bone in detail, rather than offering a broad overview.
