Osteonecrosis de maxilares asociada al uso de bifosfonatos: Revisión de 491 casos

Abstract

In the last years, the number of patients presenting jaw osteonecrosis associated with the use of bisphosphonates (BIONJ) has increased. This is due to increased consumption of bisphosphonates, which are associated with the treatment of carcinomas with bone metastases, multiple myeloma, osteoporosis, osteopenia and metabolic diseases such as Paget's disease. The aim of this review is to analyze the number of cases of patients who developed jaws osteonecrosis-associated with the use of bisphosphonates, published from June 2006 to April 2010. In this review, we referred to the databases Pubmed-Medline, Scielo and Spanish Medical Index, including limits on the search to collect BIONJ cases published from 2006 up to now. The selected papers presented cases in which the patients who received bisphosphonates developed BIONJ. We found 491 cases of BIONJ in total, of which 49.3% correspond to women, 32% to men and 18.7%, did not establish gender. Most of these cases occurred in the mandible and associated particularly with zoledronic acid. In the coming years it is expected that the number of patients who develop this complication increase, particularly in women, who are more and more prescribed this medication for the osteoporosis treatment.
