Bisphosphonates-Related Osteonecrosis of the Jawsrefers to the exposed bone in the maxillofacial region (jaws) that fails to heal within 8 weeks in a patient who Is currently or was previously treated with bisphosphonates, and has not had radiation therapy to the jawsIncidence in the early USA the report was 0.8–12% with intravenous BP and 0.7/100,000 (0.0007%) with oral BP In Europe, the incidence was 95/100,000 (0.095%) with intravenous administration and 1/100,000 (0.001%) with oral administration in Australia  BRONJ occurred in 1.15% of intravenously administered patients and in 0.04% of the orally administered patients Taken together, these reports suggest that the incidence of BRONJ with intravenous (IV) BPs has greater risk than oral BPs References 1-    Tardast, A., Sjöman, R., Løes, S., & Abtahi, J.
