Compared with bitewing radiographs, panoramic radiographs in orthodontics are less effective for detecting which condition?

• A. Proximal caries
• B. Overall jaw relationships
• C. Tooth eruption status
• D. Spacing anomalies

Answer: (A)

Proximal caries require a clear view of the contact areas between adjacent teeth, and bitewing radiographs provide that with high resolution and minimal distortion. Panoramic images, while useful for surveying the full dentition and jaw relationships, have more distortion and lower resolution in the interproximal regions, plus potential overlap of structures. This makes early or small proximal caries harder to detect on a panoramic than on bitewings. The panoramic view is better suited for assessing overall jaw relationships, eruption status, and spacing patterns, which is why it’s favored for orthodontic planning. So, compared with bitewings, panoramic radiographs are less effective for detecting proximal caries.
