Dentin (/ ˈ d ɛ n t ɪ n / DEN-tin) (American English) or dentine (/ ˈ d ɛ n ˌ t iː n / DEN-teen or / ˌ d ɛ n ˈ t iː n / 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. It is usually covered by enamel on ...
Reactionary dentin is formed by odontoblasts when the injury does not damage the odontoblast layer. Reparative dentin is formed by replacement odontoblasts when the injury is so severe that it damages a part of the primary odontoblast layer. Thus a type of tertiary dentin forms in reaction to stimuli, such as attrition or dental caries.
Dentin hypersensitivity is a relatively common condition. [4] [3] Due to differences in populations studied and methods of detection, the reported incidence ranges from 4-74%. [3] Dentists may under-report dentin hypersensitivity due to difficulty in diagnosing and managing the condition. [4]
[2] [3] Most of the crown is composed of dentin ("dentine" in British English) with the pulp chamber inside. [4] The crown is within bone before eruption. [5] After eruption, it is almost always visible. The anatomic root is found below the CEJ and is covered with cementum. As with the crown, dentin composes most of the root, which normally has ...
Derived from the mesoderm, dentin is a mineralised, flexible tissue with a weight percentage of 70% inorganic material, 20% organic material, and 10% fluid. On the other hand, enamel, which comes from ectoderm, is an extremely brittle tissue that is mainly made up of water (about 3%), trace organic matrix (approximately 1%), and the mineral ...
Dentin matrix acidic phosphoprotein 1 is a protein that in humans is encoded by the DMP1 gene. [ 5 ] [ 6 ] [ 7 ] Dentin matrix acidic phosphoprotein is an extracellular matrix protein and a member of the small integrin-binding ligand N-linked glycoprotein ( SIBLING ) family (other members being DSPP , IBSP , MEPE , and SPP1 ).
Dentin phosphoprotein, or phosphophoryn, is one of three proteins formed from dentin sialophosphoprotein and is important in the regulation of mineralization of dentin, [1] one of the main constituent materials of teeth (see dentinogenesis). Phosphophoryn is the most acidic protein ever discovered and has an isoelectric point of 1.
It is 0.5–0.8 μm thick and contains enamel matrix-like protein as well as the proteins one would expect to find in dentin. It is into this hyaline layer that the initial fibers of the periodontal ligament embed themselves. [1] The hyaline layer aids cementum in binding to the dentin. [2]
