Bone scintigraphy data were collected at baseline and during the BMA treatment. BSIJmax was calculated using computer\u2010assisted diagnostic software (BONENAVI). Primary endpoints were BSIJmax in the maxilla and mandible before the clinical diagnosis of MRONJ, compared with baseline values. Secondary endpoints included area under the receiver operating characteristic curves (AUCs) for diagnosing MRONJ using BSIJmax in the maxilla and mandible.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Among 135 patients, 27 developed MRONJ during a median follow\u2010up of 74\u2009months (interquartile range, 41\u2013124\u2009months).

The AUC for mandibular BSIJmax in diagnosing MRONJ was 0.803. A mandibular BSIJmax cut\u2010off of 0.033 yielded a sensitivity and specificity of 85% and 71%, respectively, for the diagnosis of MRONJ.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The mandibular BSIJmax increased before the clinical diagnosis of MRONJ.
