ABSTRACT
OBJECTIVE: To map the current scientific landscape regarding the association/causality of medication-related osteonecrosis of the jaw (MRONJ) after tooth extraction under bisphosphonate (BF) therapy to identify knowledge gaps and guide future research. DATA: This review used the PCC strategy (P = Patient; C = Concept; C = Context). SOURCES: The MEDLINE/PubMed, Scopus, Web of Science/Clarivate Analytics, and gray literature databases were used. STUDY SELECTION: Searches were conducted by two independent reviewers until April 2024. Studies involving prior BF use and tooth extraction in humans or animals were included. Among the 176 studies, 73 (41.4 %) were in animals, and 103 (58.5 %) were in humans. Brazil led in animal studies (n = 14; 19.1 %), while Italy led in human studies (n = 14; 13.6 %). Zoledronic acid was the most cited BF (79.4 % in animals; 34.9 % in humans), with intravenous administration being most frequent (38.3 % in animals; 35.9 % in humans). The mandible was the main extraction site (n = 36 in animals; n = 41 in humans). In 91.7 % of the animal studies, sequelae compatible with osteonecrosis signs and symptoms were observed, with bone necrosis being most common (n = 39; 53.4 %). In humans, 93.2 % of studies presented 239 sequelae, with bone necrosis (n = 53; 22.1 %) being the most cited. The main location of sequelae was the mandible (n = 36 in animals; n = 41 in humans). CONCLUSIONS: Animal studies highlighted bone exposure, notably using murine models, with a significant Brazilian contribution. In human studies, bone necrosis was the main sequela of MRONJ, which has been reported by researchers in the Italy. CLINICAL SIGNIFICANCE: These findings underscore the importance of careful consideration and monitoring of patients who have a history of bisphosphonate use and who are undergoing tooth extraction, highlighting the potential risk of MRONJ.
