Which radiographic view is best for detecting interproximal caries?

• A. Bitewing radiographs
• B. Panoramic radiographs
• C. Periapical radiographs
• D. Occlusal radiographs

Answer: (A)

Bitewing radiographs are best for detecting interproximal caries because they specifically image the crowns of adjacent teeth and the spaces between them, with the film or sensor positioned to minimize overlap at the contact areas. This setup highlights any early demineralization along the proximal surfaces as a radiolucent line where the enamel and dentin meet, making small lesions visible before they spread. Other views don’t show the proximal surfaces as clearly: panoramic images cover the whole jaw but sacrifice detail and have distortion in the posterior areas; periapical views focus on the tooth roots and surrounding bone rather than the spaces between teeth; occlusal views display the chewing surfaces and overall arch shape, not the contact areas. So the bitewing view provides the most reliable, early detection of interproximal caries.
