- The cells primarily involved in the production of dentin are the odontoblasts.
- These specialized cells are located in the dental pulp and are responsible for the formation and secretion of dentin, the hard tissue that lies beneath the enamel and surrounds the pulp chamber.
- Odontoblasts extend processes into the dentinal tubules, which facilitate the mineralization process necessary for dentin formation.

- In contrast, ameloblasts are involved in enamel formation, cementoblasts produce cementum covering the tooth root, and osteoblasts are responsible for bone formation.
- Therefore, the key cell type for dentinogenesis is the odontoblast.

Key points:
- Odontoblasts: Cells that produce dentin.
- Location: Line the outer pulpal surface of the tooth.
- Function: Secrete and mineralize the dentin matrix.
- Other cells: Ameloblasts (enamel), Cementoblasts (cementum), Osteoblasts (bone).
