Dentin (/ ˈdɛntɪn / DEN-tin) (American English) or dentine (/ ˈdɛnˌtiːn / DEN-teen or / ˌdɛnˈtiːn / DEN-TEEN) (British English) (Latin: substantia eburnea) is a calcified tissue of the body and, along with enamel, cementum, and pulp, is one of the four major components of teeth.

The meaning of DENTIN is a calcareous material similar to but harder and denser than bone that composes the principal mass of a tooth.

Dentin is capped by a crown made of highly mineralized and protective enamel, and in the root, it is covered by cementum, a structure implicated in the attachment of the teeth to the bony socket. Teeth contain in their central parts dental pulps, which are usually non-mineralized.

dentin, in anatomy, the yellowish tissue that makes up the bulk of all teeth. It is harder than bone but softer than enamel and consists mainly of apatite crystals of calcium and phosphate.

2025年1月27日 · Dentin is a hard, calcified tissue that forms the bulk of a tooth’s structure, lying beneath the enamel in the crown and cementum in the root. It provides strength and support to the overlying enamel while protecting the pulp cavity, which contains nerves and blood vessels.

2024年8月11日 · Dentin is the hard, calcified tissue that makes up the majority of your tooth. This article will talk about dentin and what happens with dentin exposure.

2023年10月30日 · Dentin is the calcified connective tissue which forms the bulk of the tooth, providing it with its basic shape and rigidity. It is tougher than bone , and has a higher hydroxyapatite content, which constitutes about 70% of its dry weight.

Dentin is the hard, light-yellow, avascular tissue which lies directly under the enamel and cement. Dentin constitutes the bulk of the tooth, with a mineral content of 70% dry weight, 20% organic matrix, and 10% water (Standring, 2016; Kerr, 2007).

Dentin constitutes the main body of the tooth and is located in the inner layer of enamel and cementum, the side wall of the pulp cavity and root canal. Dentin acts as a barrier to prevent exposure of the dental pulp, reduce the conduction of hot and cold stimuli to …

Dentin, a calcified tissue beneath the enamel, is critical to dental health. While often overshadowed by the more prominent enamel, dentin’s significance lies in its protective and supportive function within the tooth structure.
