What is a common diagnostic use of panoramic radiographs in orthodontics?

• A. Evaluate overall jaw relationships, eruption status, and plan treatment
• B. Detect proximal caries with high detail
• C. Measure sulcular depth around molars
• D. Assess pulp vitality in all teeth

Answer: (A)

Panoramic radiographs are valuable in orthodontics because they provide a single broad view of the jaws and dentition, letting you assess how the upper and lower jaws relate to each other and how teeth are developing. This broader perspective helps determine eruption status, identify missing or impacted teeth, and plan the overall sequence and feasibility of treatment. It’s especially useful for seeing crowding patterns, skeletal relationships, and asymmetries that influence treatment decisions, such as whether extractions or expansions might be needed. The other options don’t fit this primary use. Proximal caries detection with high detail relies on bitewing or targeted intraoral radiographs, which provide greater resolution for caries in contacting surfaces. Measuring sulcular depth is a clinical periodontal assessment, not a radiographic task. Pulp vitality is determined through clinical tests of the tooth’s response and blood supply; radiographs cannot reliably determine vitality in all teeth.
