[Endodontic therapy in irradiated patient].

Abstract

Endodontic treatment should be the treatment of choice in irradiated patients in order to avoid extraction or to postpone it to a less threatening post irradiation period. Regressive changes in the irradiated area supplied by these damaged vessels appear so far to be of a nutritional nature. Endodontic procedures should be accomplished with judicious precision and gentle. The tooth should never leave "open for drainage" in an irradiated patient. Shorter lengths during instrumentation of the root canals would appear to be more desirable than over extended lengths. Canal obturation with gutta percha by means of lateral condensation is effective. This report demonstrated multiple endodontic treatments in two patients after cancericidal radiation to the head and neck area. The successful treatment had been followed up after 2 years.
