den·tin

(den'tin), Do not confuse this word with dentine.
The ivory forming the mass of the tooth. About 20% is organic matrix, mostly type I collagen, with some elastin and a small amount of mucopolysaccharide; the inorganic fraction (70%) is mainly hydroxyapatite, with some carbonate, magnesium, and fluoride. The dentin is traversed by a large number of fine tunnels known as tubules, running from the pulp cavity outward; within the tubules are processes from the odontoblasts.
