Summary

Oral ulceration linked to bone necrosis can occur on the mandible. Trauma to the periosteum, combined with anatomical factors, causes this focal ulcerative lesion.

Area of Science:

  • Oral pathology
  • Dental medicine
  • Surgical pathology

Background:

  • Oral mucosal ulceration is a frequent symptom of diverse pathologies.
  • Identifying etiological factors is crucial for effective management of oral lesions.

Purpose of the Study:

  • To describe a specific type of oral ulceration.
  • To elucidate the pathogenesis of ulceration overlying the lingual shelf and mylohyoid ridge.

Main Methods:

  • Clinical case description.
  • Histopathological examination of ulcerated tissue and underlying bone.
  • Analysis of etiological factors including trauma and anatomical predispositions.

Main Results:

  • Oral ulceration was observed on the mucosa overlying the lingual shelf and mylohyoid ridge of the mandible.
  • Lesions were associated with bone sequestration, indicating ischemic bone necrosis.
  • Trauma to the periosteum was identified as a key factor in the ulcer's development.

Conclusions:

  • Focal ulcerative lesions on the mandible can result from ischemic bone necrosis.
  • The pathogenesis involves trauma to the periosteum, leading to bone necrosis.
  • Local anatomical factors and potential systemic factors may predispose individuals to this condition.
