Osteonecrosis of the Jaw (ONJ)

With ZOMETA, ONJ is uncommon, may be prevented, and can be managed1-3

The causes of ONJ are not well understood1,4,5

  • There have been uncommon reports of ONJ in cancer patients receiving chemotherapy, radiation therapy, corticosteroids, RANKL inhibitors, or bisphosphonates6
  • A causal relationship between bisphosphonate therapy and ONJ has not been established5,6

ONJ is uncommon2,3,6

  • A 2008 comprehensive review by the MD Anderson Cancer Center revealed that ONJ is uncommon2,3
    • ONJ occurred in 0.73% of all cancer patients treated with bisphosphonates
    • The frequency was slightly higher in patients with breast cancer or multiple myeloma
  • A retrospective adjudication process applied to data from the ZOMETA clinical trial programme in tumour-induced hypercalcaemia, multiple myeloma, and bone metastases from solid tumours demonstrated a prevalence of 0.1% among 16,900 patients exposed to ZOMETA as of November 20063

ONJ may be prevented or managed through relatively simple, appropriate dental procedures1,5,7

  • Appropriate preventive dentistry, such as dental exams and good oral hygiene, should be performed prior to treatment with ZOMETA1,5
  • Once on treatment, patients should avoid invasive dental procedures and continue with dental cleanings and exams1,5,7
Bisphosphonate-related osteonecrosis stages & treatment strategies

*Recommended treatment protocol per American Association of Oral and Maxillofacial Surgeons (AAOMS), updated January 2009. AAOMS has defined stage 0 as patients with no clinical evidence of exposed/necrotic bone but with nonspecific symptoms for which symptomatic treatment may be advisable.
