Which kind of x-ray is described as Periapical (PA)?

• A. Periapical (PA)
• B. Full Mouth Series (FMX)
• C. Panorex (PANO)
• D. Bitewings (BW)

Answer: (A)

Periapical radiographs focus on a single tooth from crown to root tip and include the surrounding bone and supporting structures. This is why the image described as Periapical (PA) is the correct one—the label directly identifies the type of radiograph that shows the entire tooth and its periapical region. This kind of image is especially useful for assessing root health, apical pathology, and bone around the tooth. The other options don’t fit this label: a Full Mouth Series is a set of radiographs (often including PA views and bitewings) rather than a single PA image; Panorex is a panoramic image of the entire jaw, not a periapical view; bitewings image the crowns and interproximal spaces, not the periapical area of the tooth roots.
