RESUMEN
Bisphosphonate-related osteonecrosis of the jaw (BRONJ) occurs mainly in female patients. In males the occurrence rate is low, which seems to be related to the low incidence of osteoporosis in men. Unfortunately, BRONJ tends to be ignored in general dental clinics in male patients with a history of osteoporosis treatment. BRONJ occurred in a male patient due to the clinician's lack of interest in the patient's history. In this case, the male patient was on bisphosphonate therapy because of a orchiectomy, and a dental treatment was performed without consideration of his medical history, resulting in BRONJ. We performed careful examinations and treatment with antibiotics and surgical operations. The postoperative healing was successful. In light of this particular case, we concluded that careful listening to the patient's history is very important.
