Dental ankylosis is associated with which type of root resorption?
Show answer and explanation
Correct answer: C. Replacement resorption
- A. Surface resorption is small, self-limiting, and not the hallmark of ankylosis.
- B. Inflammatory resorption is driven by infected necrotic pulp/bacteria, with radiolucency — a different process.
- C. Correct. In ankylosis the PDL is lost and bone fuses directly to root; the root is gradually replaced by bone (replacement resorption / 'ankylotic' resorption).
- D. Internal resorption originates from within the canal (pulpal), not from ankylosis.
