Bisphosphonates are a group of medicines used in the treatment of oncological osteoporosis, Paget disease and osteogenesis imperfecta. They significantly interfere with the regeneration processes of bone tissue and have a tendency to accumulate in the areas of increased bone remodeling, i.e., the maxilla and the mandible. One of their most serious and problematic side effects is the induction of bisphosphonaterelated osteonecrosis of the jaw (BRONJ), characterized by an exposed, necrotic bone in the maxillofacial area, which lasts longer than 8 weeks, in the case of a patient who is using or was using bisphosphonates and who did not undergo radiotherapy in this anatomical area. Dentistry manipulations are one of the factors which may increase the risk of BRONJ occurrence. The existing recommendations for preventing osteonecrosis are ambiguous. Some authors recommend that the bisphosphonate therapy be discontinued prior to dental procedures, while others say that there is no evidence for the effectiveness of interrupting the therapy. There is also no unequivocal attitude toward antibiotic prophylaxis. According to this research, each case should be considered individually, primarily having regard to the good of a patient.
