Adenomatoid odontogenic tumour- revisted

Abstract

Adenomatoid odontogenic tumor, fourth most common odontogenic tumor in the Indian population. It is the most common odontogenic tumor associated with impacted teeth. The diagnosis stands important as it is most commonly associated with an impacted maxillary canine. An adenomatoid odontogenic tumor (AOT) is a tumor of epithelial origin that shows duct-like structures and the epithelium forms whorled masses of cells in a scant fibrous stroma. AOT is not a common odontogenic neoplasm and it was first described by Steensland in the year 1905. Initially, AOT was described as pseudoadenoameloblastoma by Dreibladt in the year 1907 and it was considered a distinct entity and some of them believed it to be a variant of ameloblastoma by Stafne in the year 1948.
