Adenomatoid Odontogenic Tumor (AOT)


  • Benign. Relatively rare.
  • It occurs in young patients (70% of cases in patients younger than 20 years).
  • Most common site: anterior maxilla.
  • Often surrounds an entire unerupted tooth (most commonly the canine).
  • Usually well defined, well corticated. Some tumors are totally radiolucent; others show evidence of internal calcification.
