What arches are seen in a Cephalometric radiograph?

• A. One Arch
• B. Both Arches
• C. Maxillary Arch
• D. Mandibular Arch

Answer: (B)

Cephalometric radiography is a lateral view of the head used to study the relationships of the skull, maxilla, and mandible. In this view you can see both dental arches—the upper (maxillary) and lower (mandibular) arches—because the image captures the profile of the entire jaw region. This allows evaluation of how the arches relate to each other and to the cranial base, which is essential for diagnosing skeletal patterns and planning orthodontic treatment. A single arch image wouldn’t show the full relationship, whereas a cephalogram is meant to show both arches in one view.
