American Heritage® Dictionary of the English Language, Fourth Edition
- n. One of the cells forming the outer surface of dental pulp that produces the dentin of a tooth.
Century Dictionary and Cyclopedia
- n. A cell by which dentine is developed; a cell which produces dentinal tissue, the special substance which largely composes teeth. They occur in the layers of well-defined cells on the surface of the dentinal wall of a tooth, constituting the so-called membrana eboris, and become converted into dentine by the process of calcification. An odontoblast differs from an osteoblast only in the result of its formative activity.
GNU Webster's 1913
- n. (Anat.) One of the more or less columnar cells on the outer surface of the pulp of a tooth; an odontoplast. They are supposed to be connected with the formation of dentine.
- n. (Zoöl.) One of the cells which secrete the chitinous teeth of Mollusca.
- odonto- + -blast (Wiktionary)
“In this way the entire thickness of the dentin is developed, each canaliculus being completed throughout its whole length by a single odontoblast.”
“In the nucleus DMP1 might play an important role in the regulation of genes that control osteoblast or odontoblast differentiation.”
