What is the primary role of panoramic radiography in suspected salivary gland stones?

• A. Panoramic radiograph for screening
• B. Focused CT for screening
• C. MRI
• D. Ultrasound

Answer: (A)

Panoramic radiography serves as a broad, low-dose screening tool to look for radiopaque calcifications in the region of the salivary glands and their ducts. Because it provides a single, wide view of the jaws and surrounding soft-tissue areas, it can reveal obvious sialoliths that are radiopaque and located along the submandibular duct or within a gland, guiding further evaluation. If something suspicious is seen, more focused imaging such as ultrasound or CT can be used to confirm and precisely localize the stone, assess ductal dilation, and plan management. While dedicated CT or MRI and ultrasound have roles in detailed assessment, the primary role of the panoramic image in suspected salivary stones is as a screening exam to detect radiopaque calcifications and flag cases that need additional imaging.
