Odontoblasts reside in which tooth tissue?

Odontoblasts reside in which tooth tissue?

• A. Dentin
• B. Cementum
• C. Pulp
• D. Enamel

Answer: (C)

Odontoblasts are the cells responsible for forming dentin, and their bodies sit in the dental pulp along the outer border of the pulp chamber. They align as a peripheral layer just beneath the dentin, with their cellular processes extending into dentinal tubules to secrete dentin during development and even in response to injury. After tooth eruption, the pulp remains the living tissue housing these cells, whereas enamel contains no living cells, cementum is produced by cementoblasts on the root surface, and dentin is the tissue they help form. So, odontoblasts reside in the pulp.
