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

| − | *Secrete [[Dentine - Anatomy & Physiology|dentine]] which is a mineralised matrix of collagen I, [[Dentine - Anatomy & Physiology|dentine]] and proteins

| − | *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).
