Research Interests / Professional Overview:

Dr. Fleisher is the principle investigator of a study designed to understand the pathogenesis of Osteonecrosis of the Jaw (ONJ).

What is Osteonecrosis of the Jaw?  Osteonecrosis of the jaw, often referred to as "ONJ", refers to an area of dead bone in the jaw.

How do I know if I have osteonecrosis of the jaw?  While some patients may not experience any symptoms, some may have exposed bone, pain, swelling and/or infection. An oral health care specialist can typically make this diagnosis after a taking a thorough medical history and performing a careful examination.

What causes osteonecrosis of the jaw?  The cause of ONJ is unknown. There are many risk factors for ONJ that include antiresorptive therapy (i.e., bisphosphonates, denosumab), poor oral hygiene, cancer, chemotherapy, infection (osteomyelitis), smoking and alcohol abuse.  ONJ may be associated with dental extractions. ONJ associated with radiation therapy to the head and neck is called osteoradionecrosis.

How is osteonecrosis of the jaw treated? There are many strategies for managing ONJ.  For more information about ONJ, please contact Dr. Fleisher.
