Medication-related osteonecrosis of the jaw (MRONJ) is developed even in the patients who are edentulous and treated with short-term bisphosphonate therapy and oral administration. It sometimes causes lethal sepsis in patients who have multiple health problems such as diabetes, cirrhosis, steroid use for interstitial pneumonia, sepsis, and spinal disk herniation.

We hypothesized that local infection plays a critical role in the pathogenesis of medication-related osteonecrosis of the jaw (MRONJ). Recent developments in molecular methods have revolutionized new approaches for the rapid detection of microorganisms including those difficult to culture. The aim of our study is to identify the bacterial profiles in MRONJ by microbiological culture and polymerase chain reactions (PCR). A retrospective analysis was performed on MRONJ patients from 2008 to 2014. The bacterial profile from MRONJ bone samples was determined using microbiological culture and PCR...

INTRODUCTION: Osteonecrosis of the jaw (MRONJ) linked to bisphosphonate treatment has specific characteristics that render its therapeutic management challenging for clinicians. Poor response to standard treatment makes it essential to take special precautions when treating this type of disease; therefore, antibiotic prophylaxis and/or antibiotic therapy have been proposed as effective and helpful tools in these situations. OBJECTIVES: This article seeks to assess published evidence in order to evaluate the different protocols used for antibiotic prophylaxis and/or antibiotic therapy in the general context of patients treated with bisphosphonates...

Background Recent evidence suggests that medication-related osteonecrosis of the jaw (MRONJ) can be caused by a number of anti-resorptive and anti-angiongenic agents not limited to bisphosphonates. A working knowledge of these medications is important for dental practitioners.Methods A total of 129 general dental practitioners (GDPs) were surveyed regarding their awareness of MRONJ and its causes.Results More than 90% of the GDPs sampled were unaware of anti-resorptive and anti-angiogenic medications other than bisphosphonates that had the potential to cause MRONJ...

Surgical debridement of medication-related osteonecrosis of the jaw (MRONJ) lesions is far less predictable than lesion resection. Margins for surgical debridement are guided by surrogate markers of bone viability, such as bleeding and bone fluorescence, which limit debridement to visibly necrotic bone. In contrast, surgical resection is extensive, including a substantial portion of surrounding bone. The concept that the MRONJ lesion is a composite of affected but viable ("compromised") and necrotic bone is supported by histopathological data...

BACKGROUND: Multiple myeloma (MM) is characterized by a neoplastic proliferation of plasma cells primarily in the bone marrow. Bisphosphonates (BP) are used as supportive therapy in the management of MM. This study aimed to analyze the incidence, risk factors, and clinical outcomes of medication-related necrosis of the jaw (MRONJ) in MM patients. METHODS: One hundred thirty MM patients who had previous dental evaluations were retrospectively reviewed. Based on several findings, we applied the staging and treatment strategies on MRONJ...

Medication-related osteonecrosis of the jaw (MRONJ) has been associated with medications that include bisphosphonates (BPs), denosumab, bevacizumab and sunitinib. Ziv-aflibercept is a recombinant human vascular endothelial growth factor (VEGF) receptor which has been used to treat patients with various advanced solid tumors. We report three patients without a history of the use of medications known to cause MRONJ presenting with jaw osteonecrosis typical for MRONJ following therapy with ziv-aflibercept. All patients had metastatic gastrointestinal cancer treated with ziv-aflibercept and were evaluated for MRONJ because of exposed bone in the oral cavity...

Medication-related osteonecrosis of the jaws (MRONJ) is an adverse side effect of several drug therapies, including bisphosphonates (BPs). Osteonecrosis of the jaw specifically related to BP therapy is usually referred to using the acronym BRONJ. However, no consensus has yet been reached regarding the most appropriate management of BRONJ. The greatest success rates have been recorded with surgical removal of necrotic bone. In particular, erbium:yttrium-aluminum-garnet (Er:YAG) laser-assisted surgery has shown significantly better results than conventional surgical approaches...

REVIEW
A J Lyons, P A Brennan
Pentoxifylline has been used to treat complications related to fibrosis for over 20 years. Formerly used to treat those after radiotherapy such as osteoradionecrosis (ORN), it is now being tried for medication-related osteonecrosis of the jaw (MRONJ), which can occur after prolonged use of bisphosphonates. We review theories on the formation of fibrosis in patients with ORN, discuss the pharmacology of pentoxifylline and vitamin E, and report published outcomes. To our knowledge no prospective randomised controlled trial has investigated the benefits of these agents in cases of ORN, but reported outcomes in many published case series are encouraging...

OBJECTIVES: The receptor activator of nuclear factor kappa-B ligand (RANKL) inhibitors are novel clinically effective agents that inhibit osteoclast differentiation, function, and survival by binding to RANKL. Medication-related osteonecrosis of the jaw (MRONJ), caused as a result of treatment using denosumab, is a newly emerging type of bone necrosis, the exact pathogenesis of which is unknown. Several studies recently showed that the intravenous administration of mesenchymal stem cells (MSCs) improved the osteonecrosis of the jaw, and it was hypothesized that paracrine effects by secretomes from MSCs are the main constituent...
