Abstract

This retrospective cohort study was conducted on 73 patients diagnosed with Osteoradionecrosis of the Jaws (ORNJ), treated in the Department of Maxillofacial Surgery of  the National Hospital of Odonto – Stomatology to describe some criteria including clinical symptoms, radiographic images and related factors of ORNJ in these patients by consulting medical records and interviewing patients. The study results show that the majority of lesions presented in the mandible, particularly in the angle region. The prominent symptoms were deep pain, fistula, exposed necrotic bone, tingling and numbness in the lips and cheeks, and trimus. Radiographic feature was ill-defined cortical destruction without sequestration. The patients’ major oral health problems  were poor dental hygiene and periodontitis. The related factors were tooth extraction, non-standard dental prosthesis and even root canal treatment.


Keywords: Osteoradionecrosis of the jaws, clinical symptoms, radiography images, related factors.
