Synonym(s): dentinum [TA], ebur dentis, substantia eburnea [L. dens, tooth]

den·tin

(den'tin) The ivory forming the mass of the tooth. Calcified tissue that is not as hard as enamel but harder than cementum. About 20% is organic matrix, mostly a fibrous protein collagen, with some elastin and a small amount of mucopolysaccharide; the inorganic fraction (70%) is mainly hydroxyapatite, with some carbonate, magnesium, and fluoride. It is traversed by closely packed tubules running from the pulp cavity outward; within the tubules are processes from the odontoblasts.
