Focal Idiopathic Osteosclerosis

Definition: A localized hyperplasia of bone within the jaws, often associated with external root resorption of adjacent teeth.

Radiographic Features:

  • Location: Can occur anywhere in maxilla or mandible
  • Edge: Well-defined
  • Shape: No specific shape; variable
  • Internal:
    • Radiopaque
    • Radiopacity similar to cortical bone
  • Number: May be single or multiple

Key Diagnostic Signs:

  • Localized area of increased bone density
  • Possible root resorption of adjacent teeth

Clinical Significance:

  • Usually asymptomatic and discovered incidentally
  • No treatment typically required unless causing complications
  • May complicate orthodontic tooth movement in affected area
  • Important to monitor for potential impact on adjacent teeth

Note: While similar in appearance to enostosis, focal idiopathic osteosclerosis is more likely to be associated with root resorption. Regular follow-up is advisable to monitor for any changes or effects on surrounding structures.
