Which cells are responsible for resorption of dental hard tissue (root resorption)?

Correct answer: C. Odontoclasts

• A. Incorrect. Osteoclasts resorb BONE, not tooth structure (though they are very similar cells).
• B. Incorrect. Odontoblasts FORM dentin; they do not resorb it.
• C. Correct. Odontoclasts are the clastic cells that resorb dental hard tissues (e.g., physiologic primary root resorption, pathologic resorption).
• D. Incorrect. Osteoblasts FORM bone.
