Which type of x-ray would you use to examine the entire dentition in one image?

• A. Panorex
• B. Bitewing
• C. Periapical
• D. Cephalometric

Answer: (A)

The main idea is to survey the entire dentition in one exposure. A panoramic radiograph achieves this by rotating the X-ray source and detector around the head to create a single wide image that includes both dental arches from back to back teeth. This makes it ideal for viewing overall tooth position, eruption patterns, impacted teeth, and jaw relationships in one shot, which is exactly what you need when you want the entire dentition in one image. Bitewings, in contrast, show primarily the crowns and interproximal spaces of posterior teeth and are used for caries risk and bone level assessment between adjacent teeth. Periapical images focus on the tip of the tooth and surrounding bone, typically covering only a few teeth at a time and requiring multiple films to view the whole dentition. Cephalometric radiographs image the facial skeleton and are used for orthodontic or craniofacial analysis, not for presenting all teeth together in a single view.
