What is AOT in oral pathology?
Adenomatoid odontogenic tumor (AOT) is a rare tumor of epithelial origin comprising 3% of all the odontogenic tumors. It is a benign, painless, noninvasive, and slow-growing lesion, with a relative frequency of 2.2-13% and often misdiagnosed as an odontogenic cyst on clinical examination.
What causes Keratocystic odontogenic tumors?
The genetic mutation that causes the syndrome is inherited. This syndrome results in the development of multiple odontogenic keratocysts within the jaws, multiple basal cell skin cancers and other characteristics.
What is Unicystic Ameloblastoma?
Unicystic ameloblastoma (UA) refers to those cystic lesions that show clinical, radiographic, or gross features of a mandibular cyst, but on histologic examination show a typical ameloblastomatous epithelium lining part of the cyst cavity, with or without luminal and/or mural tumor growth.
What is the treatment of ameloblastoma?
Ameloblastoma treatment usually includes surgery to remove the tumor. Ameloblastoma often grows into the nearby jawbone, so surgeons may need to remove the affected part of the jawbone. An aggressive approach to surgery reduces the risk that ameloblastoma will come back. Surgery to repair the jaw.
How can you tell the difference between AOT and Dentigerous cysts?
The characteristic radiographic difference between dentigerous cyst and follicular AOT is that the radiolucency in the former is never associated with part of the root (always attached at the cervix) whereas in the latter it is most commonly associated with the part of the root.

Presence of these changes may remain clinically undetected and carry a significant influence on treatment and outcome.

Which is the best description of an AOT tumor?
The histological typing of the WHO defined the AOT as a tumor of odontogenic epithelium with duct-like structures and with varying degrees of inductive change in the connective tissue. The tumor may be partly cystic, and in some cases the solid lesion may be present only as masses in the wall of a large cyst [ 14 ].
