Correct answer: A. greater content of inorganic salts
- A. greater content of inorganic salts
- B. Lasser content of inorganic salts
- C. Greater stainability
- D. Greater content of large collagen fibres
Explanation
Peritubular dentin is more highly mineralized than intertubular dentin, so it has a greater inorganic salt content and narrows the dentinal tubule lumen. It contains less collagen than intertubular dentin, not more large collagen fibres.
