odontoblast

 [o-don´to-blast]
one of the connective tissue cells that deposit dentin and form the outer surface of the dental pulp adjacent to the dentin.

o·don·to·blast

(ō-don'tō-blast),
One of the dentin-forming cells, derived from mesenchyme of neural crest origin, lining the pulp cavity of a tooth; odontoblasts are arranged in a peripheral layer in the dental pulp, each with an odontoblastic process extending part way into the dentinal tubules; the cells generally are columnar in the coronal pulp but are more cuboidal in the radicular area and adjacent to tertiary dentin.
[odonto- + G. blastos, sprout, germ]

Cells participating in the activation of stem cells in the pulp (mesenchymal mucous tissue of the tooth) in the regenerative process of a damaged tooth are not only odontoblasts, which are dentinogenic cells, but also the cells located below them.
The H&E staining was used to investigate the dental pulp response, considering the morphological aspects of the inflammatory response, such as the intensity (i.e., mild, moderate, or severe) and type of inflammatory infiltrate (polymorphonuclear [PMN] or mononuclear [MN]), organization of the odontoblast layer, blood vessel condition, and presence of abscesses or necrosis (Six, Decup, Lasfargues, Salih, & Goldberg, 2002; Vier-Pelisser, Figueiredo, Cherubini, Braga Filho, & Figueiredo, 2007; Parolia et al., 2010).

Root canal instrumentation produces a smear layer, consisting of organic and inorganic material, mainly formed by dentin, pulp tissue remnants, odontoblast processes and, in a contaminated canal, there are also bacteria on dentin walls.
