On a radiograph, the image shows amalgam tattoo (radiopaque foreign body in soft tissue). What is the most likely diagnosis?

Correct answer: D. Foreign body

• A. Cemento-osseous dysplasia appears in periapical bone around tooth roots, typically with a mixed radiolucent-radiopaque pattern in bone — not a soft tissue finding.
• B. A complex odontoma is a mixed radiopaque-radiolucent lesion associated with teeth — not a soft tissue scattered radiopacity.
• C. Normal anatomy would show recognizable anatomical structures without a foreign radiopaque deposit.
• D. An amalgam tattoo appears radiographically as an irregular, scattered radiopacity within soft tissue (typically buccal mucosa, gingiva, or palate) with no associated bone destruction. It is the most common pigmented lesion of the oral mucosa and represents amalgam particles embedded in soft tissue.
