Which radiographic views help assess bone height around posterior teeth?

• A. Bitewings and periapicals
• B. Panoramic radiographs only
• C. Occlusal radiographs only
• D. Lateral cephalometric radiographs

Answer: (A)

To assess bone height around posterior teeth, you want radiographs that clearly show the crestal bone levels and the surrounding interproximal bone. Bitewing views are ideal for this because they capture the crown-to-root area and the alveolar crest of posterior teeth in a single image, making it easy to compare bone height between adjacent teeth and detect early bone loss. Periapical views complement this by imaging the entire tooth from crown to apex and the adjacent bone, allowing precise assessment of vertical bone height around each posterior tooth and the status of the supporting bone at the root.

Panoramic radiographs provide a broad overview but suffer from distortion and lower resolution in the posterior crestal areas, so they’re not the best for measuring precise bone height. Occlusal radiographs show different aspects of the arches and are useful for other purposes, not primarily for evaluating crestal bone height around posterior teeth. Lateral cephalometric radiographs are focused on skeletal relationships of the jaw and face, not on the dental bone height around posterior teeth.

Thus, bitewings and periapicals together offer the most reliable information for assessing bone height around posterior teeth.
