title: Characteristic features of the adenomatoid odontogenic tumour on cone beam CT.
abstract: OBJECTIVE
  To illustrate characteristic features of adenomatoid odontogenic tumour (AOT) on CBCT.
  
  
  METHODS
  The archived CBCT and panoramic radiographs of eight patients histopathologically diagnosed as AOT were analysed. The radiographic features displayed on both radiographic images were carefully described and compared.
  
  
  RESULTS
  All eight AOT cases presented as unilocular and well-demarcated lesions on both CBCT and panoramic images. CBCT images displayed three-dimensional interpretation of AOT lesions, especially the detailed intralesional radiopacities. Numerous discrete radiopaque foci scattered in the lesion with evident contrast to the radiolucent background could be considered as one of the characteristic features of AOT on CBCT.
  
  
  CONCLUSIONS
  Compared with panoramic radiography, CBCT seems to possess better potential in diagnosing AOT.
