Which type of radiograph images a single tooth and its surrounding structures?

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

Answer: (A)

A periapical radiograph captures a single tooth and its surrounding structures. It includes the tooth from crown to apex and the adjacent supporting bone, making visible the periapical area, lamina dura, and the periodontal ligament space. This focused view lets you assess root morphology, periapical pathology, bone level around that tooth, and potential fractures—information that’s essential when diagnosing issues tied to one tooth. Bitewing images, by contrast, show crowns and the spaces between teeth across several adjacent teeth, mainly to evaluate interproximal caries and bone height at the crestal level, not a single tooth in detail. Panoramic radiographs provide a broad view of the entire jaws and surrounding structures in one image, which is useful for overall assessment but lacks the detailed view of a single tooth and its immediate supporting tissues. Cephalometric radiographs are lateral skull views used for assessing skeletal relationships and orthodontic planning, not for examining a specific tooth and its surrounding structures.
