Which view primarily shows one arch and is often used for examining a single arch?

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

Answer: (A)

When you want a close, detailed look at the teeth and bone of a single dental arch, a focused anterior periapical radiograph is the most suitable view. It centers on the front teeth (the anterior segment) and uses a small, specific field that captures the roots and surrounding bone of that arch with high resolution. This makes it ideal for evaluating issues like trauma to the front teeth, root integrity, and periapical conditions in that arch, without including the opposite arch. Other views are designed to visualize larger areas: bitewings show both arches and emphasize interproximal spaces and bone levels between posterior teeth; panoramic (panorex) provides a broad image of both arches and surrounding structures; cephalometric radiographs depict a lateral view of the skull for orthodontic assessment rather than detailed analysis of a single arch. That broader scope is why those views aren’t as well suited for examining just one arch in detail.
