[The rare case of osteonecrosis of the jaws in a patient treated with bisphosphonates for osteoporosis].

Bisphosphonates are used primarily in patients with bone metastases and osteoporosis One of the local complications, less well-known to doctors, associated with the use of bisphosphonates is osteonecrosis of the jaw (Biophosphatate Related osteonecrosis of the jaw--BRONJ). It affects approximately 1-10% of patients and may cause diagnostic difficulties because of its similarity to a primary focus in the bone. This issue can be encountered by the doctors of various specialties who use bisphosphonates. The purpose of this study is to present a case of the patient with BRONJ symptoms following the administration of bisphosphonate therapy, which can occur in the doctors practice. Concluding, maintaining good health of the oral cavity before starting the therapy reduces the incidence of BROKJ. Before starting bisphosphonate therapy, all patients should be referred to dental consultation to assess the potential foci of infection in the mouth.
