title: [Benign maxillofacial tumours. Odontogenic tumours].
abstract: Regarding the 2004 actualization of the classification of benign odontogenic tumours published by IARC and WHO, we have reviewed our files in order to explain the new parameters established in this actualization. Histologically tree groups can be considered depending on the tissue involved: a) odontogenic epithelium with mature fibrous stroma without odontogenic ectomesenchyme, b) odontogenic epithelium with odontogenic ectomesenchyme, with or without tissue formation, and c) mesenchyme and/or odontogenic ectomesenchyme, with or without odontogenic epithelium. Every tumour appears with clinical features, radiographical and specific epidemiology data to complete the cases, in adittion to recurrences and appropriate surgical resection.
