ABSTRACT
This paper presents a case of osteonecrosis of the jaw related to zoledronic acid (5 mg) administered once yearly to treat osteoporosis. A 79-year-old woman who has been treated for osteoporosis for 5 years with 5 applications of zoledronic acid was referred for evaluation. The patient had been submitted to dental implant placement and there was no osseointegration. On clinical examination, suppuration and exposed bone on the alveolar ridge were observed. Radiographic examination revealed an osteolytic area and bone sequestration. Both clinical and radiological features were suggestive of osteonecrosis. The treatment consisted of surgery to remove the affected bone completely. The patient is asymptomatic at 9 months after surgery. Dentists and oral surgeons should be alert to the possibility of osteonecrosis related to the use of once-yearly injections of zoledronic acid for the treatment of postmenopausal osteoporosis.
RESUMO
O presente estudo teve como objetivo apresentar um caso de osteonecrose dos maxilares associada ao uso de ácido zoledrônico (5 mg) administrado uma vez ao ano para tratar a osteoporose. Uma mulher de 79 anos de idade estava em tratamento de osteoporose por 5 anos com 5 aplicações do ácido zoledrônico foi encaminhada para nossa avaliação. A paciente tinha sido submetida à colocação de implante dental e não houve osseointegração. Ao exame clínico, supuração e osso exposto no rebordo alveolar foram observados. Os exames radiográficos revelaram uma área osteolítica e sequestro ósseo. Ambos os aspectos clínicos e radiográficos eram sugestivos de osteonecrose. O tratamento consistiu de cirurgia para remover todo o osso afetado. A paciente está assintomática há 9 meses (desde a cirurgia). Cirurgiões-dentistas e cirurgiões orais devem estar atentos para a possibilidade de osteonecrose relacionada ao uso de injeções anuais de ácido zoledrônico para tratamento da osteoporose pós-menopausa.
