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.

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).
