WebJan 4, 2015 · After a mild lesion (caries, abrasion, and/or restorative material), odontoblasts and Hoehl’s cells contribute to the formation of reactionary dentin (also named tertiary dentin) beneath a calciotraumatic line. After irreversible alteration of these cells, or a pulp exposure, pulp cells contribute to the formation of reparative dentin. WebDentin 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.

WebThe resulting matrix deposited on the pulpal aspect in the region of microbial invasion is termed reactionary dentin (Rd). A characteristic feature of Rd is the presence of fewer tubules that typically display apparent constrictions when viewed in semi-thin sections (Charadram et al., 2012; Farahani et al., 2010). WebDentin located in the root walls of teeth that have been endodontically treated contains 9% less moisture than root dentin of vital teeth. 403 That is a positive feature for dentin adhesion.
