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 ...
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 ...
Dentin dysplasia (DD) is a rare genetic developmental disorder affecting dentine production of the teeth, commonly exhibiting an autosomal dominant inheritance that causes malformation of the root. It affects both primary and permanent dentitions in approximately 1 in every 100,000 patients. [ 1 ]
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.
Due to the close relationship between dentin and pulp, they are frequently considered together as the dentin-pulp complex. [43]: 118 The teeth and gums exhibit normal sensations in health. Such sensations are generally sharp, lasting as long as the stimulus. [18] There is a continuous spectrum from physiologic sensation to pain in disease. [18]
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 ).
