title: [Imagery and orthodontics: trends, present and future].
abstract: From the first dental image in 1895 and the first image of the head in 1896 by Otto Walkhoff to 3D modern cephalic assessment there has been a continuous evolution in imaging techniques. Digital cephalic volume data processing allows 2D and 3D reformations in accordance with morphologic, topographic and biodimensional anatomic needs. In France, Jacques Treil demonstrated its application in cephalometry through his CT scan research. The transcription of European Directives to national laws leads to rigorous radioprotection measures. The worldwide spread of cone beam technique devoted specifically to dentomaxillofacial imaging should now reduce the reluctance of orthodontists to provide radiological examinations to children by significantly reducing radiation exposure. This is certainly the technique of the future.
