[Current evidence-based approaches and international guidelines in primary and secondary prevention strategies of medication-related osteonecrosis of the jaws].

Introduction

The presumably multifactorial pathomechanisms of medication-related osteonecrosis of the jaws have not been fully elucidated so far. Management of this rare but serious side effect is a real challenge and requires a multidisciplinary approach. Aim: The aim of the authors was to take stock of our present knowledge about the pathogenesis, risk factors, clinical manifestations and the possibilities of prevention and treatment in the medication-related osteonecrosis of the jaws. In addition, the available international guidelines are compared and the evidence-based, stage-specific conservative and adjuvant therapeutic approaches are also reviewed, having regard to special aspects of medical and dental care. Method: In the last 5 years - due to the increasing number of disorder-oriented database - the number of available systematic reviews, recommendations and meta-analyses has escalated significantly which we reviewed and compared.

Results

Since the last Position Paper published by the taskforce of the American Association of Oral and Maxillofacial Surgeons, novel pharmacological groups with the potential to induce osteonecrosis have come in the clinical scope, further elaborating the nomenclature of the disease and further specifying patient groups. The sphere of patients at risk has broadened and novel patient groups (rheumatologic-osteological, immunosuppressed, transplanted or oncological patients treated with monoclonal antibody, known as 'target therapy') are expected to develop this serious side effect.

Conclusion

Although a number of issues are still open regarding the treatment of the disorder, evidence-based, individualized, stage-adapted therapeutic approaches have replaced the previous empirical treatment. Orv Hetil. 2020; 161(6): 214-223.
