A drug interruption of 3 or more months prior to tooth extraction lowered MRONJ risk (AOR 0.11; 95% CI, 0.07\u20130.17). Stratified by drug type, denosumab users had significantly lower risk of MRONJ after extraction (AOR 0.14; 95% CI, 0.07\u20130.27) compared to those on other medications. Factors of drug duration \u2265\u200924\u2009months, &lt;\u20093\u2009months of interruption, and posterior mandibular tooth extraction posed the highest synergistic MRONJ risk (AOR 80.29; 95% CI, 33.05\u2013195.09).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Our results suggest an association between a three\u2010month ART interruption prior to tooth extraction and reduced MRONJ risk, especially in long\u2010term ART patients undergoing posterior mandibular extractions.
