Zoology.

A. adj.

(Of a tooth) occurring in only a single dentition; (of a dentition) occurring in an animal as the only dentition. Also, of an animal: growing only one set of teeth.

1964 T. J. Parker & W. A. Haswell Text-bk. Zool. (ed. 7) II. 864 Usually mammals have two distinct sets of teeth developed... Sometimes there is only one set present. Accordingly disphyodont and monophyodont dentitions are distinguished.
