Show answer and explanation
Correct answer: D. Peripheral ossifying fibroma
- A. Incorrect – dense fibrous tissue without mineralized product and rarely recurs.
- B. Incorrect – highly vascular granulation tissue, no bone formation.
- C. Incorrect – that diagnosis would require multinucleated giant cells on histology, not osseous tissue.
- D. Correct – a reactive gingival nodule that contains mineralized (osseous/cementoid) tissue and has a notable recurrence rate.
