Which kind of x-ray is described as Full Mouth Series (FMX)?

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

Answer: (B)

The main idea here is that FMX stands for a complete set of dental radiographs that documents all teeth and the surrounding bone. It isn’t a single view like a periapical or a bitewing, and it isn’t one broad image like a panoramic. A full mouth series combines multiple periapical radiographs—covering each tooth and its apex and surrounding bone—with bitewing images to show interproximal surfaces and bone levels. This comprehensive set provides a full picture of the dentition and supporting structures, which is why it’s described as a full mouth series. The other options describe individual types of images that only show part of the mouth: periapical focuses on roots and surrounding bone for a few teeth, a panoramic is a single wide view of both arches, and bitewings show interproximal surfaces but not the entire dentition.
