The WHO classification of odontogenic and maxillofacial bone tumours, last published in 2017, is a subset of the WHO classification of head and neck ~~tumors~~tumours (4^th edition), ~~that~~which lays out a histological classification system for neoplasms and other tumours related to the odontogenic apparatus.
