Which of the following conditions would occlusal radiographs be used to diagnose?

Occlusal radiographs are primarily used to view the entire dental arch and the surrounding structures, making them especially valuable for diagnosing certain conditions. One of the key uses of occlusal radiographs is to locate retained roots and impacted teeth. The broad, compressed view these radiographs provide enables the clinician to see the spatial relationships between teeth and the jaw, which is crucial for identifying teeth that have not fully emerged or are misaligned, as well as for visualizing any remnants of teeth that may be lodged in the bone after extraction.

This technique allows for a better assessment of the size and position of the retained roots, which may not be as easily detectable with periapical or bitewing radiographs. It enhances the overall understanding of dental arch anatomy, aiding practitioners in planning treatment for these specific dental issues effectively.
