Which radiograph is most appropriate for diagnosing a sialolith in the submandibular duct?

Correct answer: B. Occlusal

• A. Panoramic can sometimes show calcifications but is not the preferred view for submandibular sialoliths.
• B. Correct. The occlusal radiograph (cross-sectional technique) is the most appropriate view for detecting sialoliths in the floor of the mouth/submandibular duct region, as it images the floor of mouth in a plane that captures calcified stones.
• C. Waters view is for the paranasal sinuses, not for salivary stones.
• D. Periapical radiographs do not capture the submandibular duct area.
