Overview

Classification[1][2]

  • Stage 0: Patients who present with unspecific symptoms or radiographic findings but without clinical evidence of necrosis.
  • Symptoms:
  • Dull pain in the mandible body which can radiate to the temporomandibular joint
  • Unexplained odontalgia
  • Maxillary sinus pain
  • Altered mental status
  • Clinical findings
  • Not caries associated periapical or periodontal fistula
  • Unexplained loosening of the teeth
  • Radiographic findings
  • Trabecular pattern changes
  • Thickening of the periodontal ligament
  • Osteosclerosis regions which involves alveolar bone and the basilar bone
  • Alveolar bone loss or resorption
  • Stage 1: Asymptomatic patients, without infection evidence who present an exposed necrotic bone or fistula. Radiographic findings mentioned above can be found in patients with stage 1
  • Stage 2: Patients with exposed necrotic bone or fistula and signs of infection, usually symptomatic. Radiographic findings mentioned above can be found in patients with stage 2
  • Stage 3: Patients with the characteristics of stage 2 plus one or more of the following conditions:
  • Pathologic fracture
  • Osteolisis which reaches the sinus floor or the external border of the mandible
