Which statement about panoramic radiographs is true?

• A. They provide a broad overview of the dentition and jaw structures.
• B. They are best for precise interproximal caries detection.
• C. They replace bitewing radiographs.
• D. They cannot detect impacted teeth.

Answer: (A)

Providing a broad overview of the dentition and jaw structures is the main strength of panoramic radiographs. Because they capture the entire arch in one image, they’re ideal for screening, treatment planning, and assessing eruption patterns, missing teeth, jaw relationships, and large pathologies or anomalies such as impacted teeth. However, their resolution and magnification can obscure fine details, and overlapping structures can make precise assessment of small proximal caries less reliable, so they’re not the best choice for detecting early interproximal caries. They also do not replace bitewing radiographs, which offer higher detail of contact areas and bone levels in a localized field. Panoramic radiographs can reveal impacted teeth, so the statement that they cannot detect impacted teeth isn’t correct.
