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]

A specialized connective tissue cell, lying in the outer surface of the dental pulp, that produces DENTINE.

Demineralized dentin matrix induces odontoblastic differentiation of dental pulp stem cells.
Furthermore, as noted in some cases (1,7,9), marked globular dentine, increased predentin width and intact odontoblastic cell layer were seen in the present case.
Up to the present, we've known that PC is able to facilitate odontoblastic differentiation on dental pulp cells, [sup][18] encourage hard tissue deposition [sup][24] and show good biocompatibility.
Strong cytoplasmic HMGB1 signal was noted in both odontoblastic and subodontoblastic cell layers (A and C, arrow), as well as in odontoblast processes in tubules of the predentin.
DPSCs' possible employment as therapeutic tool in regenerative endodontics is supported by several in vivo studies which showed that human DPSCs transplanted under the skin of immunocompromised mice formed pulp/dentin-like tissue complexes after odontoblastic differentiation [7, 35-37].
As a pulp capping or pulpotomy medicament in both animals and humans, MTA preserved normal pulp architecture, caused little or no inflammation and maintained an intact odontoblastic layer in almost all samples (Table 1) [Dominguez et al., 2003; Agamy et al., 2004].
Additionally, the odontoblasts, which are the dentin-producing cells, are located near the pulp with the odontoblastic processes being restricted to the inner one-third of the dentinal tubules.
Effect of Platelet-rich Fibrin on Odontoblastic Differentiation in Human Dental Pulp Cells Exposed to Lipopolysaccharide.
Odontoblastic differentiation was induced after the application of Biodentine on exposed rat pulps, and resulted in a dentin bridge formation adjacent to Biodentine, similar to MTA after 14 days and 30 days.
Metformin significantly increased the mRNA expression of odontoblastic gene markers, including DSPP, DMP-1, Runx2, and OCN mRNA (Figure 5).
Many studies have demonstrated that water cooling is required to reduce the increase in pulpal temperature and improve the ablation rate during cavity preparation; this is to avoid odontoblastic alterations and inflammatory response in the pulp chamber beneath the preparation.
