Overview
The odontoblasts are cells in the enamel organ which forms the tooth. They secrete Enamel Organ#Dentinedentine.
Properties
Odontoblasts are derived from mesenchyme and are composed of a single layer of elongated columnar cells. They are at the dental-pulp border. They secrete Enamel Organ#Dentinedentine which is a mineralised matrix of collagen I, Enamel Organ#Dentinedentine and proteins.
The first layer of Enamel Organ#Dentinedentine 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. The rate of Enamel Organ#Dentinedentine synthesis is increased during repair as it is innervated (but still acellular).
