Which statement is true about bitewing radiographs?

• A. Assessing the overall length of tooth roots
• B. Detecting interproximal caries between posterior teeth
• C. Visualizing the temporomandibular joint
• D. Evaluating soft tissue calcifications

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. That combination makes them ideal for detecting caries that occur between adjacent teeth, especially in the posterior region, so detecting interproximal caries between posterior teeth is the true statement. They don’t show the full length of tooth roots—that’s better seen on periapical radiographs. They also don’t image the temporomandibular joint; evaluating the TMJ requires other views or imaging modalities. Likewise, soft tissue calcifications are not the focus of bitewings, which are targeted at caries detection and assessing proximal bone levels.
