Which radiograph would you choose to visualize only the anterior region of a single arch?

• A. Anterior PA
• B. Posterior PA
• C. Bitewing
• D. Panorex

Answer: (A)

Focusing on the front teeth requires a projection that limits the view to the anterior region. The anterior periapical radiograph is designed to capture the front teeth and the surrounding supporting tissues, providing a confined field of view that isolates the anterior portion of a single arch. Other options broaden the view: a posterior periapical would include the back teeth, not just the front; bitewings primarily show the crowns and interproximal areas of posterior teeth and don’t isolate the anterior region; a panoramic image covers the entire arch of both jaws. So for visualizing only the anterior region, the anterior periapical radiograph is the correct choice.
