Which intraoral projection is used to image a large area of the maxilla or mandible?

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

Answer: (A)

This item tests which intraoral projection can capture a broad area of either jaw in one image. Occlusal radiographs are designed for a wide field within the mouth, using a larger film or sensor and a specific beam angle to image extensive regions of the maxilla or mandible in a single exposure. They can show both anterior and posterior areas, the palate, floor of the mouth, and surrounding structures, making them ideal when you need a large anatomical view. In contrast, periapical and bitewing images focus on small areas around individual teeth or groups of teeth, and panoramic radiographs, while covering a large area, are extraoral and not intraoral. So the projection that best images a large area of the maxilla or mandible intraorally is occlusal radiographs.
