Purpose: To conduct a systematic review of the literature to detect the effect of anti-resorptive drugs (ARDs) and their administration characteristics in the development of medication-related osteonecrosis of the jaw (MRONJ) in osteoporosis patients. Methods: Systematic search in PubMed, Web of Sciences and Cochrane Library was performed for relevant studies to July 2016. Population variables (age, gender, comorbidities, medications, preceding events, number of patients with MRONJ), ARDs and clinical variables were abstracted independently from these articles. Results: The 44 eligible studies described 680 MRONJ cases in osteoporotic patients. The mean age of MRONJ patients was 69.7 +/- 5.2 years. It was more common in females. Mandible was the most common site. Alendronate was the most frequently administered ARD. Oral route of administration was noted in 86.7% of the patients. The mean duration of BPs intake was 50.4 +/- 19 months. Extraction was the most frequently preceding event followed by dentoalveolar surgery. Corticosteroids or immunosuppressants were the most common concomitant medications in MRONJ. Conclusion: A long duration of ARDs administration seems to be an important risk factor in MRONJ development. Patients under treatment with corticosteroids or immunosuppressants might be at a higher risk even if the BPs duration is less than 4 years.
