Drug-induced osteonecrosis of the jaw: the state of the art

Abstract: Osteonecrosis of the jaw (ONJ) is a rare adverse event of antiresorptive drugs such as bisphosphonates (BP) and denosumab (DMAb). The diagnosis of ONJ is considered in cases where exposed bone in the maxillofacial region does not heal within 8 weeks in a patient previously treated with an antiresorptive agent. In patients with osteoporosis, ONJ is reported as a very rare adverse event while in oncologic patients with bone metastases or malignant hypercalcemia the incidence is significantly higher (up to the 1-… Show more

“…During remodeling and healing of bone fractures, osteoblasts activate various bone morphogenetic proteins that stimulate the production of VEGF (Vascular Endothelial Growth Factor) factor, which is necessary for the formation of new blood vessels, or angiogenesis [5].…”

“…Osteoporotic changes worsen in postmenopausal females and can variably affect any bone, but more frequently the femoral neck, vertebrae, and distal radius where unique patterns of bone derangement emerge. This lesional microtopography is now gaining particular interest in bones traditionally considered less affected by osteoporosis such as the jaw (Figures 1A,B) because of the increased request of prosthetic implants (5) and as a unique site for chronic inflammation and aseptic osteonecrosis during antiresorptive therapy (6).…”

“…A osteonecrose dos maxilares causada pelo uso de medicamentos ["medicine drug related osteonecrosis of the jaw (MRONJ)"], tais como os antirreabsortivos, caracteriza-se pela presença de exposição óssea ou osso que pode ser examinado por meio uma fístula intra ou extraoral na região dos maxilares, persistente por mais de 8 semanas, durante ou após tratamento com BPs, sem histórico de radioterapia na região maxilofacial (RUGGIERO, 2014). Esse efeito adverso de difícil resolução tem mecanismos desconhecidos, causa destruição severa nos maxilares (MIGLIORATI, 2006) e sua gravidade varia de acordo com a via de administração, a dose, a frequência e o tempo de uso do medicamento (BASSO, 2013;FERREIRA JÚNIOR; CARDOSO; BARBOZA, 2007; ALIJOHANI et al, 2017;FASSIO et al, 2017).…”

“…Considerando que a MRONJ, patologia óssea multifatorial de difícil tratamento (FASSIO et al, 2017), pode ser desencadeada por tratamentos odontológicos envolvendo tecido ósseo, como doença periodontal, lesões periapicais, instalação de implantes, cirurgia oral, e extrações (ALIJOHANI et al,2017;FASSIO et al, 2017;NICOLATOU-GALITIS et al, 2019), sendo a última responsável por mais de 50% dos desencadeamentos da enfermidade, pode-se considerar também a ocorrência espontânea (RUGGIERO, 2014; KUROSHIMA; SASAKI; SAWASE; 2019), o propósito deste estudo consistiu em analisar a capacidade de diferenciação osteoblástica de células-tronco mesenquimais (CTMs) de ratos que foram tratados cronicamente com alendronato de sódio ou ácido zoledrônico.…”
