WebJun 17, 2016 · The carious lesion may develop at a slow rate. In such case, they are involved in the formation of reactionary (or tertiary) dentin. Rapidly progressing carious lesions lead to the formation of an atubular dentin of the osteodentin type or to the complete absence of tertiary dentin. This rapidly progressing lesion management often leads to pulp ... 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).

Formation of this form of dentin involves secretion of matrix metalloproteinases from dentinal tubules. These enzymes are also used during the formation of dentin in embryogenesis, so this this is another example of wound repair recapitulating embryonic development.
