AbstractOsteonecrosis of the jaws is a complication after treatment with antiresorptive drugs. Bisphosphonates (BPs) are widely used to treat conditions with bone metastases of malignant tumors such as multiple myeloma, breast cancer, prostatic cancer, as well as hypercalcemia of malignancy, osteoporosis, Paget’s disease, and osteogenesis imperfecta. Denosumab is an antiresorptive agent that is used for the treatment of osteoporosis or metastatic bone diseases. These antiresorptive agents improve the quality of life of patients by increasing strength and bone mineral density, and reducing the risk of bone fractures. More than a decade had passed since the first publication of this pathology, and the occurrence of the disease, its pathophysiology, and proper treatment methods are still not fully elucidated. Prevention is critical in medication-related osteonecrosis of the jaw, because the treatment is difficult, and there are no universally accepted treatment protocols. There is an accepted approach of palliation of symptoms and controlling the associated infections. Treatment may follow one of three procedures: conservative management of pain, conservative or extensive (segmental) surgery, depending on the disease stage.

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 1-10% of the patients). The pathophysiology of ONJ is still not completely understood but it is multi-factorial. ONJ is a condition associated with poor oral health, oral surgery, and use of antiresorptive agents. Prevention is of paramount importance especially in cancer patients, in whom the large majority of cases of ONJ (>90%) are reported, but it should also be considered in osteoporotic patients, especially during dental surgical procedure. Some simple prevention procedures are effective in reducing the risk of its appearance. When ONJ unfortunately occurs, the large majority of patients can be managed conservatively. In conclusion, ONJ is a rare condition associated with antiresorptive drugs. Both osteoporotic and oncologic patients should be well informed about its low absolute risk and regarding the fact that the benefits of antiresorptive therapy far outweigh this potential risk of ONJ.

Bisphosphonates (BPs) are a class of synthetic drugs commonly used to treat bone metastasis and various bone diseases that cause osseous fragility (such as osteoporosis). Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a common complication in patients who received BPs, especially intravenously. Recently, osteonecrosis of the jaw (ONJ) caused by chemotherapeutic not belonging to BPs drug class has been reported. For this reason, it has been proposed recently to rename BRONJ in antiresorptive agents related osteonecrosis of the jaw (ARONJ), to include a wider spectrum of drugs that may cause osteonecrosis of the jaw. The most debated topic about ARONJ/BRONJ is therapy. The most adequate procedure is far from being standardized and prevention seems to play a pivotal role. In our study, we considered 72 patients with BRONJ with nonsurgical therapy, surgical therapy, and surgical therapy with platelet rich plasma (PRP) gel to evaluate its therapeutic effect in promoting ONJ wounds healing. Good results showed by PRP in improving wound healing give away to case-control randomized studies that could give definitive evidence of its effectiveness.

Antiresorptive agent-related osteonecrosis of the jaw (ARONJ) is an adverse event induced by antiresorptive agents (ARAs). The purpose of this study was to evaluate variables, mainly surgery and hyperbaric oxygen (HBO) therapy, associated with treatment outcomes in patients with a diagnosis of ARONJ at a single center. We enrolled consecutive patients who presented to our hospital for the management of stage 2 or 3 ARONJ between January 2003 and December 2019. The relationship between potentially predictive factors and outcome variables was examined using statistical analyses, along with a subgroup analysis based on disease stage. Of 252 patients included in this study, 206 had stage 2 ARONJ and 46 had stage 3 ARONJ. There were 119 patients with osteoporosis and 133 with malignant disease. In total, 139 patients were healed, and the healing rate of patients with stage 3 ARONJ was lower than that of patients with stage 2 ARONJ. With regard to the combination of surgery and HBO therapy, most patients underwent HBO before and after surgery. In the univariable analysis, surgery showed a therapeutic effect in both stage 2 and 3 ARONJ, whereas HBO showed a therapeutic effect in stage 2 ARONJ. In the multivariable analysis for stage 2 ARONJ, extensive surgery showed a stronger association with healing than conservative surgery, whereas ≥46 sessions of HBO therapy was less associated with healing than was non-HBO therapy. Our findings suggest that extensive surgery is highly effective against ARONJ regardless of disease stage if there is a sequestrum separation and systemic tolerance, whereas HBO therapy before and after surgical approach can be effective. Further studies are needed to identify treatment strategies for patients with treatment-refractory ARONJ who may be forced to undergo long-term HBO therapy with the expectation of sequestrum separation.

There is no agreement of data in the subject of implant failure and the development of osteonecrosis in patients receiving antiresorptive agents. The purpose of this systematic review is to evaluate whether dental implants placed in patients on antiresorptive medication have an increased failure rate and whether the implant placement or the implant existence are risk factors for developing medication-related osteonecrosis of the jaw (MRONJ). An electronic search was conducted in PubMed/Medline and all publications fulfilling the inclusion criteria were included. The search was completed by a hand research of the references cited in all electronic identified publications and resulted in 411 articles. According to the inclusion criteria, 32 studies were included with a total of 5221 patients, 12 751 implants, 618 cases of implants loss and 136 cases of MRONJ analyzed. It cannot be established that antiresorptive medication affects the dental implant survival rates, because of small number of studies, most of them characterized by a low level of quality. The risk of MRONJ as an early or late complication is also not well established. Therefore, successful dental implant procedures on patients receiving antiresorptive medication might be possible, but more studies need to be carried out in the future to verify this topic. Apart from intravenous antiresorptive drugs, which remain an absolute contraindication, dental implantology in patients under antiresorptive medication is not a contraindication but it must be accompanied with a careful treatment planning, patients must be informed about the possible complications and large follow up periods are essential.

AbstractAntiresorptive drugs operate in the bone metabolism modulation and are widely used in the treatment of bone metastases and bone losses related to hormonal deficiency. Although this therapy shows satisfactory results, there are adverse effects associated with its use, such as osteonecrosis of the jaws. Medication-related osteonecrosis of the jaws (MRONJ) is, therefore, a serious and challenging condition with important implications in dentistry. The aim was to conduct a narrative literature review on anti-resorptive drugs and their latest repercussions on the maxillary bones. The review was carried out through a bibliographic search using Decs/Mesh descriptors of interest, in Portuguese and English, in the PubMed, Virtual Health Library (VHL) and Scielo databases. After applying the inclusion and exclusion criteria, a total of 33 studies were selected for analysis. It can be noticed that therapy with anti-resorptive agents is complex, especially in dental practice, since MRONJ is a complication that is difficult to manage. Regarding the therapeutic options, these are divided into conservative, surgical or adjuvant therapy, however, there are no protocols in the literature, and there is no consistency regarding the indication of the suspension of the drug administration - "Drug Holiday". Thus, it is important that the multidisciplinary team seeks strategies that minimize complications and promote control over the use of these drugs. In addition, there is a need for investigations that contribute with guidelines for the management and control of adverse effects resulting from therapy with antiresorptive drugs.

ResumoAs drogas antirreabsortivas atuam na modulação do metabolismo ósseo e são indicadas para o tratamento de metástases ósseas e perdas ósseas relacionadas à deficiência hormonal. Ainda que esta terapia apresente resultados satisfatórios, observam-se efeitos adversos associados ao seu uso, como a osteonecrose dos maxilares. A osteonecrose dos maxilares associada ao uso de medicamentos (OMAM) é, portanto, uma condição séria e desafiadora com implicações importantes na Odontologia. O objetivo foi realizar uma revisão narrativa de literatura sobre as drogas antirreabsortivas e suas respectivas repercussões nos ossos maxilares. A revisão foi realizada através de busca bibliográfica utilizando descritores Decs/Mesh de interesse, em português e inglês, nas bases de dados PubMed, Biblioteca Virtual de Saúde (BVS) e Scielo. Após aplicação dos critérios de inclusão e exclusão, um total de 33 trabalhos foram selecionados para análise. Pode-se constatar que a terapia com agentes antirreabsortivos é complexa, sobretudo na prática odontológica, visto que a OMAM é uma complicação de difícil manejo. Em relação às condutas terapêuticas para esta condição, divide-se em terapia conservadora, cirúrgica ou adjuvante, todavia, não existem protocolos validados na literatura, bem como não há consistência quanto à indicação do intervalo de suspensão da administração da droga - “Drug Holiday”. Desse modo, é importante que a equipe multidisciplinar busque estratégias que minimizem as complicações e promovam o controle no uso dessas drogas. Além disso, nota-se a necessidade de realizar investigações que contribuam com diretrizes para o manejo e controle dos efeitos adversos decorrentes da terapia com medicamentos antirreabsortivos.

There is a current debate about the extent to which antifracture efficacy of antiresorptive drugs are related to changes in bone mineral density (BMD). In vitro studies show that most of the variability in bone strength is related to BMD, and prospective studies have shown that low BMD is an important predictor of fracture risk. It seems that higher levels of bone turnover are also associated with increased fracture risk. Over the short term, a reduction in activation frequency or resorption depth would lead to fewer (and/or shallower) resorption sites and refilling of existing sites initially. There is also evidence that inhibiting resorption allows bone to respond to mechanical demands, preferentially thickening critical trabeculae, and this may help compensate for reduced connectivity. Each of these mechanisms would increase BMD and would disproportionately improve bone strength. Over the long term, maintaining bone mass and preventing loss of structural elements would result in progressively greater differences in BMD and fracture risk over time, relative to untreated women. The conceptual model predicts that both the short- and long-term antifracture efficacy of antiresorptive drugs will depend on the extent to which treatment can increase and maintain BMD. To examine this issue, we compiled data from clinical trials of antiresorptive agents and plotted the relative risk of vertebral fractures against the average change in BMD for each trial. The confidence intervals are large for individual trials, and there was substantial variability in antifracture efficacy at any given level of change in BMD. Overall, however, trials that reported larger increases in BMD tended to observe greater reductions in vertebral fracture risk. Poisson regression was used to quantify this relationship. The model predicts that treatments that increase spine BMD by 8% would reduce risk by 54%; most of the total effect of treatment was explained by the 8% increase in BMD (41% risk reduction). These findings are consistent with the short-term predictions of the conceptual model and with reports from randomized trials. The small but significant reductions in risk that were not explained by measurable changes in BMD might be related to publication bias, measurement errors, or limitations of current BMD technology.

<p>Bisphosphonates (BP) are routinely used in the management of metastatic bone diseases and malignancies neoplasms, but there is an adverse effect of their chronic use called bisphosphonate-related osteonecrosis of the jaw (BRONJ). Treatment for BRONJ is challenging and complex, as there is still no definitive treatment protocols and the various treatments described in the literature have success variables indexes. In this sense, this study aims to emphasize the responsibility of dentist about the knowledge of BRONJ and report a clinical case that the surgical therapy was the best treatment option. Male patient, sixty-nine years old, asked for dental care complaining about bone exposure. On the anamneses, he reported the use of BP due to cancer history. The intra oral examination revealed exposed bone in the lower right molar region extending to retromolar trigon region on lingual side. There was conservative treatment with antibiotic therapy and mouth rinses of chlorhexidine 0.12 %, but not obtaining success. Therefore, we opted for the surgical removal of necrotic bone area and the tooth involved. The postoperative was within normal standard. The knowledge of dentist about this pathology is essential to prevent, diagnose and treat this disease the most appropriate way. Although the treatment of BRONJ remains challenging and complex, surgical therapy is a treatment option for lesions in early clinical stages and resistant to conservative treatment, providing a better prognosis and quality of life for the patient.</p><p> </p><p><strong>Keywords</strong></p><p>Bisphosphonate-associated osteonecrosis; Mandible; Oral surgical procedures.</p>

Abstract Context Antiresorptive therapy significantly reduces fracture risk in patients with benign bone disease and skeletal-related events (SREs) in patients with bone metastases. Osteonecrosis of the jaw (ONJ) is a rare, but severe condition, manifested as necrotic bone lesion(-s) of the jaws. ONJ has been linked to the use of potent antiresorptive agents, termed as Medication Related ONJ (MRONJ). Methods A working group of the European Calcified Tissue Society (ECTS) and two experts performed an updated detailed review of existing literature on MRONJ incidence, characteristics, and treatment applied in bone diseases with variable severity of skeletal insult, ranging from osteoporosis to prevention of cancer treatment-induced bone loss and SREs in cancer patients with bone metastases. We aimed to identify the differences in various aspects of MRONJ among these distinct patient categories and provide recommendations on how to mitigate the risk and optimally manage MRONJ in each one of them. Results The risk for MRONJ is much higher in patients with advanced malignancies compared to those with benign bone diseases, because of the higher doses and more frequent administration of antiresorptive agents in individuals with compromised general health, along with co-administration of other medications that predispose to MRONJ. The overall risk for MRONJ is considerably lower than the benefits in all categories of patients. Conclusions The risk for MRONJ largely depends on the underlying bone disease and the relevant antiresorptive regimen applied. Physicians and dentists should keep in mind that the benefits of antiresorptive therapy far outweigh the risk for MRONJ development.

Vitamin D and calcium are considered crucial for the treatment of bone diseases. Both vitamin D and calcium contribute to bone homeostasis but also preserve muscle health by reducing the risk of falls and fractures. Low vitamin D concentrations result in secondary hyperparathyroidism and contribute to bone loss, although the development of secondary hyperparathyroidism varies, even in patients with severe vitamin D deficiency. Findings from observational studies have shown controversial results regarding the association between bone mineral density and vitamin D/calcium status, thus sparking a debate regarding optimum concentrations of 25-hydroxyvitamin D and calcium for the best possible skeletal health. Although most of the intervention studies reported a positive effect of supplementation with calcium and vitamin D on bone in patients with osteoporosis, this therapeutic approach has been a matter of debate regarding potential side effects on the cardiovascular (CV) system. Thus, the aim of this review is to consider the current evidence on the physiological role of vitamin D and calcium on bone and muscle health. Moreover, we provide an overview on observational and interventional studies that investigate the effect of vitamin D and calcium supplementation on bone health, also taking into account the possible CV side-effects. We also provide molecular insights on the effect of calcium plus vitamin D on the CV system.

Bisphosphonates are first-line therapy for osteoporosis, with alendronate, risedronate, and zoledronate as the main treatments used globally. After one year of therapy, bisphosphonates are retained in bone for extended periods with extended anti-fracture effects after discontinuation. Due to this continued fracture protection and the potential for rare adverse events associated with long-term use (atypical femoral fractures and osteonecrosis of the jaw), a drug holiday of two to three years is recommended for most patients after long-term bisphosphonate therapy. The recommendation for a drug holiday up to three years is derived primarily from extensions of pivotal trials with alendronate and zoledronate and select surrogate marker studies. However, certain factors may modify the duration of bisphosphonate effects on a drug holiday and warrant consideration when determining an appropriate time off-therapy. In this narrative review, we recall what is currently known about drug holidays and discuss what we believe to be the primary considerations and areas for future research regarding drug holiday duration: total bisphosphonate exposure, type of bisphosphonate used, bone mineral density and falls risk, and patient sex and body weight.
