Odontoblast
An odontoblast (plural: odontoblasts) is a cell of mesenchymal origin. During tooth formation , epithelial cells of the Hertwig epithelial sheath induce the neighboring mesenchymal cells to transform into odontoblasts. Odontoblasts sit on the border between dentin and pulp . The cylindrical, palisade-shaped cells form dentine for life, which means that the size of the pulp cavity becomes smaller and smaller with age. That is why they are also called dentinoblasts or dentin formers . Their cell processes, the Tomesian fibers , protrude into the tubules that are created during dentin formation. Odontoblasts are in contact with free nerve endings and play a role in the development of the pain stimulus .
