Abstract

Osteoradionecrosis (ORN) is a noninfectious, necrotic condition of the bone occurring as a complication of radiotherapy. Most cases occur following trauma or surgical manipulation of the irradiated site. Mandible is the most common bone to be affected following head and neck irradiation. The aim was to develop a successful therapeutic approach for ORN. A spectrum of treatment modalities is practiced for ORN with variable success rate that includes simple irrigation of the affected bone to the partial or complete resection of the jaw bone. In this paper, we present two cases which had successful therapeutic approach for ORN of mandible with autologous bone marrow concentrate stem cells and allogeneic dental pulp stem cells (DPSC) with platelet rich plasma (PRP) following failure of conventional methods. Autologous bone marrow aspirate concentrate (BMAC) was injected around the socket and into the periosteum for one case, and DPSC were mixed with tricalcium phosphate and inserted at the site of the defect in one case. The patient treated with BMAC remained asymptomatic and complete bone remodeling was noticed after 1 year. The extraoral sinus was excised, and healing was uneventful without recurrence in the patient treated with allogeneic DPSC and PRP. Periodic panoramic radiographs revealed an appreciable bone formation from the 2(nd) month onward. We have successfully treated two cases of ORN with BMAC and DPSC, respectively.
