[Management of medication-related osteonecrosis of the jaw-a review of recent study results in comparison to established strategies].

BACKGROUND

Antiresorptive agents are some of the most frequently used drugs worldwide, with indications in osteology and oncology. They are generally well tolerated and display a favorable safety profile. A potentially severe unwanted side effect is medication-related osteonecrosis of the jaw (MRONJ).

PURPOSE OF THIS REVIEW: This review summarizes the latest developments in etiology, diagnosis, and treatment of MRONJ, and compares new insights with established algorithms.

METHODS

A systematic review of relevant studies exploring diagnostic methods, prospective management trials, and innovative studies on the pathogenesis of MRONJ published between 2016 and 2021 was performed. The study quality was assessed using the MINORS (methodological index for non-randomized studies) rating score.

RESULTS AND DISCUSSION: The prevalence of MRONJ in patients undergoing treatment with antiresorptive drugs for oncological reasons is remarkable (2-12%). MRONJ prevalence in patients receiving antiresorptive drugs for the treatment of osteoporosis is much lower (0.1-1%). MRONJ treatment should be initiated early and involve a surgical approach. MRONJ treatment is safe and predictable, with long-term success rates of more than 85%.
