  • It is a bone cavity not lined by epithelium.
  • Unknown etiology and pathogenesis. Almost always asymptomatic.
  • Most are found in young people under 20 years.
  • Common site: mandible, premolar/molar region
  • Monolocular, moderately well defined and moderately well corticated.
  • 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.
