Solitary (traumatic) bone cyst

  • Unknown etiology and pathogenesis. Almost always asymptomatic.
  • Most often is found in young people under 20 years.
  • Most common location: mandible, premolar/molar region.
  • Unilocular, moderately well defined and moderately well corticated radiolucency.
  • The superior margin squeezes between the roots of the adjacent teeth (scalloping).
  • There is rarely any resorption or displacement of the adjacent teeth. The teeth are usually vital.
