English abstract
Odontogenic tumours are lesions that occur solely within the oral cavity and are so named because
of their origin from the odontogenic (i.e. tooth-forming) apparatus. Odontogenic tumours comprise a variety
of lesions ranging from non-neoplastic tissue proliferations to benign or malignant neoplasms. However,
controversies exist regarding the pathogenesis, categorisation and clinical and histological variations of these
tumours. The recent 2017 World Health Organization classification of odontogenic tumours included new entities
such as primordial odontogenic tumours, sclerosing odontogenic carcinomas and odontogenic carcinosarcomas,
while eliminating several previously included entities like keratocystic odontogenic tumours and calcifying cystic
odonogenic tumours. The aim of the present review article was to discuss controversies and recent concepts
regarding odontogenic tumours so as to increase understanding of these lesions.
