'''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 '''[[Dentine - Anatomy & Physiology|dentine]]''' which is a mineralised matrix of collagen I, [[Dentine - Anatomy & Physiology|dentine]] and proteins. They are the 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|enamel]]. It is a major part of the tooth structure and is produced continually by the odontoblasts. The rate of [[Dentine - Anatomy & Physiology|dentine]] synthesis is increased during repair as it is innervated (but still acellular).
