Dentinal tubules are calcified in_______________?
Correct answer: C. Sclerotic dentin
- A. Secondary dentin
- B. Primary dentin
- C. Sclerotic dentin
- D. Interglobular dentin
Explanation
In sclerotic dentin, mineral deposits progressively occlude and calcify the dentinal tubules, reducing permeability. Interglobular dentin is hypomineralized between globules rather than tubules being calcified.
