Medication-related osteonecrosis of the jaw triggered by endodontic failure in oncologic patients.

Objectives: To describe the association between endodontic treatment failure and medication-related osteonecrosis of the jaw (MRONJ) in a cohort of oncologic patients in therapy with antiresorptive and antiangiogenic drugs.

Materials And Methods: Patients were selected as affected by MRONJ in absence of the common local risk factors (oral surgical procedures or ill-fitting dentures) but showing failure of previous endodontic treatment performed at least 6 months before the starting of antiresorptive/antiangiogenic therapies. Jaw lesions were all surgically treated and patients underwent a strict clinical and radiological follow-up.

Diode Laser Photocoagulation of Oral Venous Malformations in Patients on Anticoagulant Therapy Without Drug Discontinuation.

The diode laser is widely used for the treatment of venous malformations of the oral cavity nowadays. Anticoagulant therapy is usually modified or suspended in patients needing oral surgery, especially for vascular lesion treatment. We report a case series of venous malformations in patients on anticoagulant therapy treated by diode laser photocoagulation without drug discontinuation.
