Introduction
Odontoblasts are cells in the enamel organ which forms the tooth. They secrete dentine.
Properties
- Derived from mesenchyme
- Single layer of elongated columnar cells
- At dental-pulp border
- Outer layer of the dental papilla
- The first layer of dentine is formed on the enamel organ. As production increases, the odontoblasts are displaced from the enamel
- It is a major part of the tooth structure and is produced continually by the odontoblasts.
- Rate of dentine synthesis is increased during repair as it is innervated (but still acellular).
