Tooth development

neurovascular bundle in the tooth

In vertebrates, an odontoblast is a cell of neural crest origin that is part of the outer surface of the dental pulp, and whose biological function is dentinogenesis, which is the formation of dentin, the substance beneath the tooth enamel on the crown and the cementum on the root.

process by which teeth form

A cementoblast is a biological cell that forms from the follicular cells around the root of a tooth, and whose biological function is cementogenesis, which is the formation of cementum (hard tissue that covers the tooth root). The mechanism of differentiation of the cementoblasts is controversial but circumstantial evidence suggests that an epithelium or epithelial component may cause dental sac cells to differentiate into cementoblasts, characterised by an increase in length. Other theories involve Hertwig epithelial root sheath (HERS) being involved.

thumb | right Amelogenesis is the process of forming tooth enamel, the hard, protective outer layer of teeth. This process begins during tooth development after the initial formation of dentin (dentinogenesis), the layer beneath the enamel. The inner enamel epithelium (IEE), a layer of cells within the developing tooth, plays a crucial role by signaling the differentiation of specialized cells called ameloblasts, which then secrete the proteins and minerals that make up enamel. The formation of dentin is essential for amelogenesis to occur, and a reciprocal signaling process between the develo

anatomical entity

In animal tooth development, 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.
