Dentin

Let's look at what dentin is.

Dentin is the mineralized base of the tooth, constituting the main part of its anatomical structure and protecting the pulp, which supports the life of the tooth, from external influences. In other words, dentin is not a tissue. The pulp also provides nutrition and protection to the nerve endings or conductors that connect the dental nerve endings to the central nervous system. The nerve is one of the components of the dental system.

The formation of dentin from mesenchyme begins in the early stages of oral development and occurs approximately in the fourth week of fetal life. The formation of primary dentin occurs from the tissue that lines the oral cavity where teeth are laid, called coelomia. Structurally, coelmia is first created from body wall tissue, which will then develop to become dentin. Later, dentin differentiates into odontoblasts, cells capable of producing inorganic compounds of teeth.

To form dentin, a large amount of building substances is required (enamel and cement are necessary for the formation of crowns and roots of teeth, respectively), calcium, phosphorus, magnesium, silicon, sodium and chlorine. They are necessary to create protein compounds that make up dental tissue, thereby forming a mineralized layer - dentin. Structure

Dentin or dentinium (lat. Dens, Dentis - tooth, from Denteo - I wipe my teeth) is a layer of the outer shell of the tooth, consisting of dense organic material and containing nerve endings and blood vessels. It protects the tooth pulp and fills the gap between the inner tooth tissue
