odontoblast[ō′dänt·ə‚blast] (histology) One of the elongated, dentin-forming cells covering the dental papilla. Odontoblast the cell that deposits dentin in the teeth of man and vertebrate animals. Its cell body is adjacent to the outer layer of the pulp, and its long outgrowths are within the tubules that perforate the dentin. odontoblastenUK
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.
