[Dental treatment before radiotherapy of carcinoma of the mouth floor].

Two collectives of patients who required radiation therapy were built. In order to determine the adequate occasion and extension of surgical teeth restoration in dependence on radiation therapy, both collectives were compared. The first group implicated 21 manifest ORN. The triggers of these ORN were evaluated. In the second collective the ORN occurrence after 225 generous surgical teeth restorations before radiation therapy were prospectively fixed and analysed. In comparison of both collectives the concept of generous removing of all potential dentogene inflammations before radiation therapy was successful in prevention of the septic ORN.
