Classification on Odontogenic Tumors a Suggestion

Abstract

A classification of odontogenic tumors based on the developmental interdependence of dental tissues is suggested. The tumors are divided into two main groups, viz., epithelial and mesodermal tumors. The epithelial tumors are subdivided into purely epithelial tumors and epithelial tumors with inductive changes in the connective tissue. A revision of the prevailing concept according to which ameloblastomas are synonymous with epithelial odontogenic tumors is suggested and a new subdivision is introduced. The group of epithelial tumors with induction in the connective tissue comprises tumors composed of soft tissue and tumors containing the dental hard tissues in varying amounts.
