Bitewings show what?

Root tips and apices Interproximal surfaces and crowns Cervical margins Pulp chambers

Correct Answer:

Interproximal surfaces and crowns

Explanation:

Bitewing images are designed to show the crowns of adjacent teeth and the interproximal surfaces between them. This placement lets you see contact areas and detect caries that occur between teeth, as well as assess the height of the supporting bone between teeth in the area of the crowns. Root tips and apices are better seen on periapical radiographs, not bitewings. Cervical margins are near the gumline and aren’t the primary focus of bitewings, and pulp chambers are located inside the tooth and are not the main feature evaluated on bitewing views. So the description of interproximal surfaces and crowns best matches what bitewings show.
