Bisphosphonate associated osteomyelitis of the jaw in patients with bony exposure: prevention, a new way of thinking

Abstract: Objective There is strong evidence of a link between the use of systemic bisphosphonates (BPs) and osteonecrosis of the jaw, especially in cancer patients. Among risk factors for BRONJ, tooth extraction and immune suppressive drugs seem to have significant role on bone healing. Therefore, the importance of these parameters in development of BRONJ was reviewed in this retrospective study in two maxillofacial surgery units.Material and Methods From 2007 to 2012, 46 patients on bisphosphonate who had developed or… Show more

“…Another important aspect refers to OMJ. It is true that MRONJ and ORNJ can easily evolve into osteomyelitis once secondary infection occurs, 12 which can hinder the final diagnosis as well as the comprehension of the etiological process of each disease. However, according to the patients' records, only those cases originating from chronic or acute dentoalveolar abscesses were chosen, with no association with radiation therapy or bisphosphonates, or with any other antiresorptive drug.…”

“…Apesar da baixa taxa de complicações associadas ao seu uso, há inú-meros relatos do desenvolvimento de osteonecrose mandibular após extrações dentárias 4 . Isso pode ocorrer pelo fato de o metabolismo ósseo mandibular tornar-se lento em pacientes que fazem uso crô-nico de bisfosfonatos, o que poderia permitir que a contaminação bacteriana não fosse combatida rapidamente pela resposta imune do paciente, por isso, há maior propensão ao desenvolvimento de osteonecrose mandibular 2 . A osteonecrose pode se manter assintomáti-ca por semanas, meses ou até mesmo anos, mas, quando sinais e sintomas clínicos aparecem, estão associados com dor, mobilidade dentária, edema, eritema e ulceração 6 .…”

“…A paciente do presente estudo referia sintomatologia dolorosa na região onde estariam os dentes 46 e 47, infecção bucal recorrente e apresentava ainda hiperplasia ulcerativa associada à supuração na área afetada. Estudos epidemioló-gicos indicam uma incidência estimada de 0,1 caso para os 100.000 usuários de bisfosfonatos por ano 2 . A partir do trabalho de Lin et al 8 .…”
