Bitewing radiographs primarily assess what?

• A. Pulp vitality
• B. Interproximal caries and crestal bone height.
• C. Occlusal relationships
• D. Periodontal ligament width.

Answer: (B)

Bitewing radiographs are designed to visualize the crowns of the posterior teeth and the interproximal spaces, along with the crestal bone between them. This setup makes them ideal for detecting interproximal caries, which often develop between adjacent teeth in the contact areas, and for assessing crestal bone height as an early sign of periodontal bone loss. Pulp vitality can’t be reliably determined from bitewings alone, since vitality testing (thermal or electric) and clinical signs are used for that purpose. Occlusal relationships are evaluated clinically and with other imaging or models, not by bitewings. Likewise, evaluating the width of the periodontal ligament space is better done on periapical radiographs, which show the entire root and surrounding tissues, rather than bitewings.
