Abstract
This literature review focuses on the latest advances in the study of osteonecrosis of the jaw in cancer patients taking bisphosphonates. Prescribing bisphosphonates for the treatment of metastatic bone disease is justifiable and unavoidable measure. The action of bisphosphonates leads to increase in bone tissue strength, but significantly suppressing normal bone remodelling, essential for repair, and becomes vulnerable to mechanical trauma and bacterial invasion. The unique anatomical and physiological features of the jaw bones determine their selective damage. The disease is characterized by progressive jaw necrosis, chronic inflammation of the surrounding tissues complicated by a pathological fracture and persistent oroantral fistula, which aggravates chronic pain and leads to a deterioration in the quality of life of patients. The occurrence of bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a multifactorial process. Most often, it occurs in patients with long term treatment with zoledronic acid preparations against after tooth extraction. The fact of an increase in the incidence of osteonecrosis is undeniable for objective reasons, the main of which are an increase in cancer, an increase in the life expectancy of cancer patients and their need for bisphosphonate therapy. In the article, it was analyzed the latest scientific reports on the causes of the disease, risk factors and the pathogenesis of the disease. Data on the frequency of jaw osteonecrosis in different countries are presented. It was shown promising developments and summarizes information on existing methods for diagnosing jaw bisphosphonate osteonecrosis. Questions about the key approaches in the treatment of the disease, as well as about new experimental techniques, are examined. The main problems of the prevention of bisphosphonate-related osteonecrosis of the jaws are formulated.
