==Introduction==
Odontoblasts are cells in the enamel organ which forms the tooth. They secrete [[Dentine - Anatomy & Physiology|dentine]].

*Derived from mesenchyme
*Single layer of elongated columnar cells
*At dental-pulp border
*Secrete [[Dentine - Anatomy & Physiology|dentine]] which is a mineralised matrix of collagen I, [[Dentine - Anatomy & Physiology|dentine]] and proteins
*Outer layer of the dental papilla
*The first layer of [[Dentine - Anatomy & Physiology|dentine]] is formed on the enamel organ. As production increases, the odontoblasts are displaced from the [[Enamel - Anatomy & Physiology|enamel]]
*It is a major part of the tooth structure and is produced continually by the odontoblasts.
*Rate of [[Dentine - Anatomy & Physiology|dentine]] synthesis is increased during repair as it is innervated (but still acellular).
