Conventional Ameloblastoma
Radiographic Appearance? |
* Well-circumscribed
* Usually a multilocular radiolucency - soap-bubble or honeycomb. May be unilocular * Buccal and lingual cortical expansion/displacement * Resorption of tooth roots |
|
|
Unicystic ameloblastoma
Radiographic Appearance? |
* Circumscribed, unilocular radiolucency
* Resembles a dentigerous, primordial, or residual cyst radiographically * Often surrounding the crown of an unerupted 3rd molar |
|

Adenomatoid Odontogenic Tumor (AOT)
Radiographic Appearance? |
* Well-circumscribed, unilocular lesion, associated with the crown, but extending below the CEJ

|
|
Ameloblastic Fibro-odontoma
Radiographic Appearance? |
* Usually unilocular

|
Odontoma
Radiographic Appearance? |
* Usually RO and surrounded by a RL line. This is usually diagnostic.
