title: [Odontogenesis, organogenic model using teratomas].
abstract: The study of odontogenesis in teratomas, leads to the following observations. Conspicuous odontogenic fields are present in the vicinity of pluri-differentiated cystic structures. Tooth germs are connected to the walls of the cysts by an anastomosed dental laminar. The teeth developing in teratoma are not comparable to the normal process which is harmonized when the formation and the distribution of the various parts are concerned. They are deformed in appearance but not in the same way as the classic genetic malformations. The origin of both epithelial and mesenchymal parts is still not completely understood.
