title: [Tooth extraction in irradiated areas].
abstract: Tooth avulsion after head and neck radiotherapy has always been and is still a risk gesture when the avulsion is situated on the irradiation sites. The post-operating effects can become complicated with a delay in healing which can eventually induce an osteoradionecrosis. Dental treatment before the begining of radiotherapy aiming at the elimination of any suspicious tooth, and the generalisation of fluorotherapy aiming at limiting the decayed degeneration, did not make the avulsion indication disappear. At present tooth avulsion is still possible in case of tooth infection or broken tooth.
