Dentinogenesis is the formation of dentin, a substance that forms the majority of teeth. Dentinogenesis is performed by odontoblasts, which are a special type of biological cell on the outer wall of dental pulps, and it begins at the late bell stage of a tooth development. The different stages of dentin formation after differentiation of the cell result in different types of dentin: mantle dentin, primary dentin, secondary dentin, and tertiary dentin. ==Odontoblast differentiation== Odontoblasts differentiate from cells of the dental papilla. This an expression of signaling molecules and growth factors of the inner enamel epithelium (IEE).〔Ten Cate's Oral Histology, Nanci, Elsevier, 2013, page 170〕
