WebJul 9, 2012 · The aim of this review is to provide an overview of the basic structure and composition of dentin, including the collagenous components of the dentin organic matrix and minerals. We also describe the specific structural and functional features of the dentin–enamel junction (DEJ), mantle dentin, inter- and peritubular dentin, and pulp … WebInstead, the organic composition of this dentin is a mixture of glutamic acid-containing proteins and phospholipids, such as phosphatidylserine, phosphatidylinositol, and phosphatidylcholine, along with the presence of glycosaminoglycans. Peritubular mineralization is hypothesized to occur by adsorption along the lumen of the tubules of ...
Interfacial Chemistry of the Dentin/Adhesive Bond
Dentin (American English) or dentine (/ˈdɛnˌtiːn/ or /ˌdɛnˈtiːn/) (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 the crown and cementum on the root and … See more Prior to enamel formation, dentine formation begins through a process known as dentinogenesis, and this process continues throughout a person's life even after the tooth has fully developed. Events such as See more Dentin is classified into three types: primary, secondary, and tertiary. Secondary dentin is a layer of dentin formed after the tooth's root has fully formed. Tertiary dentin develops as a result of a stimulus, such as a carious attack or wear. See more • Dentinogenesis • Dentinogenesis imperfecta • Odontoblast • Tooth development See more Unlike enamel, dentin may be demineralized and stained for histological study. Dentin consists of microscopic channels, called dentinal tubules, which radiate outward through the dentin from the pulp to the exterior cementum or enamel border. The … See more Dentinal sclerosis Dentinal sclerosis or transparent dentin sclerosis of primary dentin is a change in the structure of … See more Elephant ivory is solid dentin. The structure of the dentinal tubules contributes to both its porosity and its elasticity. Elephant tusks are formed with a thin cap of enamel, which soon wears away, leaving the dentin exposed.

WebJan 9, 2024 · Acid etching in dentistry is an effective way to bond different types of restorations to enamel or dentin. The "smear layer" of organic and inorganic material on a tooth, which results from cavity prep, makes for a less than ideal surface for bonding. Because of the need to "disrupt" this smear layer, acid etching began in the 1970s and … regionchange.rar
