Abstract

Osteoradionecrosis of the jaws (ORNJ) is a late complication of head and neck irradiation estimated at around 3% of irradiated patients. The PENTO protocol (Pentoxyfilline and Tocopherol), with the eventual adjunction of Clodronate (PENTOCLO), showed interesting results even in advanced ORNJ. The current literature does not describe the long-term outcomes and particularly after the completion of the protocol. The PENTO or PENTOCLO protocol should be prescribed as a life-long treatment or the outcome should be monitored at least as long as the duration of the protocol after its end.
