Principles and practice of operative dentistry . The function of the ameloblast is also that of superintending the layingdown of the lime-salts which are to form almost the entire bulk of thistissue. Definition.—The term calcification comes from the Latin, calx, lime,and fiere, to become,—to become lime ; hence the term is used to expressthe physiologic process by which a deposition of calcium salts, or otherinsoluble crystalline matter, is laid down within an especially preparedmatrix, as in the formation of bone, cementum, dentin, and enamel; or apathologic deposition of calcareous materials
