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.

[ōdon′təblast′]
Etymology: Gk, odous, tooth, blastos, germ
one of the connective tissue cells in the periphery of the dental pulp that develops into the primary and secondary dentin of a tooth. Also called dentinoblast.

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

Those cells are responsible for the regenerative processes of the odontoblasts and the dentin, and under certain conditions undergo divisions which recreate an undifferentiated cell; the undifferentiated cell is then able to synthesize the extracellular matrix [4].
Local disruption and disorganization of the odontoblast layer was detected in 50% of the specimens on the third day (Table 1), together with inflammatory infiltrate that was even more prominent subjacent to the cavity preparation (Figure 1).
This is possible because of the presence of progenitor/stem cells in the dental pulp, which are able to form odontoblasts under appropriate microenviron-ments (Hao et al.
Biglycan seems to be linked to odontoblast differentiation, dentin mineralization and pulp inflammation processes.
Vitamin A plays a crucial role in the formation of ameloblasts and odontoblasts.
It is hypothesized that the stage-specific signaling differences between the primary and secondary knot is responsible for altering odontoblast differentiation, patterning, and morphogenesis in order to develop the appropriate dental anatomy for each tooth [Thesleff et al.
Calcium hydroxide has been shown to promote the differentiation of odontoblasts or odontoblast-like cells, which will form a hard tissue bridge in the pulp, i.
Inside the dentinal tubules are the odontoblast cytoplasmic extensions or Thomes fibrils.
3) The transmission of stimuli from exposed dentin to the nerve endings located in the dental pulp may occur through the odontoblast process or by means of a hydrodynamic mechanism, the latter being considered the most plausible.
