Influence of the use of bisphosphonates on the development of postextraction sequelae: scoping review with mapping evidence of in vivo studies.

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.
