odontogenesis of dentin-containing tooth odontosis The process whose specific outcome is the progression of a dentin-containing tooth over time, from its formation to the mature structure. A dentin-containing tooth is a hard, bony organ borne on the jaw or other bone of a vertebrate, and is composed mainly of dentin, a dense calcified substance, covered by a layer of enamel. Note that placoid scales found in the cartilaginous fishes presumably develop through the same processes, but are found on the dermis, rather than in the mouth or pharynx.
