Dentin is best known for its occurrence in teeth, but in early vertebrates, it was an important part of the dermal skeleton that covered most of the body, [29] [30] [31] and it persists today in a few taxa such as the coelacanth. [32] Because dentin is softer than enamel, it wears away more quickly than enamel.
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.
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 ]
Dentin is the substance between enamel or cementum and the pulp chamber. It is secreted by the odontoblasts of the dental pulp. [15] The formation of dentin is known as dentinogenesis. The porous, yellow-hued material is made up of 70% inorganic materials, 20% organic materials, and 10% water by weight. [16]
Dentin sialophosphoprotein is a precursor protein for other proteins found in the teeth. It is produced by cells ( odontoblasts ) inside the teeth (dental pulp), and in smaller quantities by bone tissues (osteoblasts and osteocytes).
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]
Dentin bonding refers to process of bonding a resin to conditioned dentin, [1] where mineral component is replaced with resin monomers to form a biocomposite comprising dentin collagen and cured resin. The adhesive-dentin interface forms a tight and permanent bond between dentin and composite resins.
Tertiary dentin (including reparative dentin or sclerotic dentin) is a form of dentin, one of the main component materials of teeth. It forms as a reaction to stimulation, including caries , wear and fractures . [ 1 ]
