“…BRONJ can occur in patients receiving BPs therapy and appears to be associated with previous dental traumatic injury; however, spontaneous occurrence has also been observed [6, 10–13]. Most of the incidences of BRONJ have been reported as a result of intravenous administration of high doses of aminobisphosphonates [14, 15], ranging from 0.8% to 12% [16, 17], whereas association of BRONJ and non-nitrogen BP is very rare [18], ranging from 0.01 to 0.34% [16, 17]. The risk of BRONJ development rises in the presence of long duration of BPs exposure, concomitant treatment with corticosteroids [19–21], chemotherapies [22, 23], antiangiogenic drugs [24–26], and hormone therapy or in the presence of patient comorbidities such as immunodeficiency, diabetes mellitus, obesity, hypercholesterolemia, and parodontopathies.…”
