What Researchers Did
Researchers reviewed the current understanding of the pathophysiology and treatment of osteoradionecrosis of the jaws, including historical theories and emerging therapeutic approaches.
What They Found
The study highlighted a shift from the long-held tissue hypoxia theory, which led to hyperbaric oxygen (HBO) use, to a new theory proposing radiation-induced fibrosis as the primary cause of osteoradionecrosis. New treatments like pentoxifylline and tocopherol, targeting fibrosis and free radical damage, have shown impressive results in reversing the process of osteoradionecrosis.
