Bisphosphonates are commonly used in the management of bone diseases, such as osteoporosis and Paget's disease, and to prevent bone complications and to treat malignant hypercalcemia in certain types of cancer. Although this class of drugs has clear evidence of medical efficacy, there are an increasing number of reports of bisphosphonate-associated osteonecrosis of the jaws that have substantial implications for the patient and for the treating dentist. This case report reviews proposed possible mechanisms of bisphosphonate-associated osteonecrosis of the jaws and describes two case reports where nonsurgical and surgical root canal treatments were precipitating factors. Recommendations for prevention and treatment of the disease follow. Thorough history taking and timely consultation with the patient's oral surgeon and oncologist are emphasized.

Background: Low-doses of bone modifying agents (LD-BMAs) compared to those used to treat bone metastases are used in breast or prostate cancer patients on adjuvant endocrine therapy to prevent Cancer Treatment Induced Bone Loss (CTIBL). Their use is associated with an increased risk of developing Medication-Related Osteonecrosis of the Jaw (MRONJ). However, there is not clarity about strategies aimed to minimize the MRONJ risk in cancer patients at different conditions as low- vs high-doses of BMA.

Background: While the surgical treatment of mandibular stage 3 medication-related osteonecrosis of the jaw (MRONJ) is well-documented, research on maxillary stage 3 MRONJ is limited. Antiresorptive medications can induce MRONJ and atypical femoral fracture (AFF), but their impact on the feasibility of using fibula flaps for reconstruction remains controversial. This study aimed to assess the surgical outcomes and functional recovery of fibula flap reconstruction for maxillary stage 3 MRONJ, considering both recipient and donor site outcomes.

Both denosumab (DMB) and bisphosphonates (BPs), antiresorptive drugs (ARDs) used for the treatment of osteoporosis and oncological disorders, are known for their potential to cause medication-related osteonecrosis of the jaws (MRONJ). Besides ARDs, statins were recently associated with MRONJ development, especially in patients taking higher doses of statins for a longer period of time. Here, we report a case of a female patient with osteoporosis using statins and treated with alendronate for 3 years who rapidly developed MRONJ stage III after only a single low dose of DMB.

Context: Fragility fractures in young adults present significant clinical challenges due to the limited evidence on the effectiveness of bisphosphonates in preventing subsequent fractures.
Objective: To evaluate the effectiveness of bisphosphonate therapy in reducing the fracture risk among premenopausal women with a history of osteoporotic fractures.
Design: A population-based retrospective cohort study was conducted using data from the National Health Insurance Service-National Sample Cohort (NHIS-NSC) in South Korea, covering the years 2003 to 2014.

Osteonecrosis of the jaw (ONJ) is a severe disease leading to decreased quality of life, but risk factors for ONJ in chronic kidney disease (CKD) patients remain unclear. We conducted a nested case-control study using a large Japanese administrative database to investigate. CKD patients were identified based on estimated glomerular filtration rate (eGFR) measurements, and ONJ cases were identified using ICD-10 codes and diagnostic terms.
