1. Adenomatoid O dontogenic Tumor Prepared By : Ibrahim Mohammed 1330146 Dental Surgery The University Of Georgia

2. Origin It originates from the enamel organ or from the remnants of dental lamina.

3. Clinical Features Occurs between 10-19 years of age. Tends to occur in the anterior portion of the jaws, twice often in the maxilla, females are affected twice as men. Mostly small size (3cm). Peripheral forms are rare. They are small sessile masses located on the facial gingiva of the maxilla.

4. Radiographical Features Asymptomatic, discovered during radiographic examination, or to know why a tooth hasn’t erupted yet. Larger sizes of the lesion cause painless expansion of the bone. 75% of the tumor appears as unilocular radiolucency involves the crown of an unerupted tooth, mostly canine.

5. Radiographical Features It’s known for being hard to differentiate Adenomatoid Odontogenic Tumor radiographically from the dentigerous cyst. Radiolucency of the adenomatoid odontogenic tumor extends apically along the root past the cementoenamel junction, and it capsulates the whole tooth in an oval shape , which helps to differentiate from the dentigerous cyst which capsulates the crown of the involved tooth only.

6. Radiographical Features In some cases adenomatoid odontogenic tumor is not related an unerupted tooth, but rather located between the roots of the erupted teeth ( ertra -follicular type). Adenomatoid odontogenic tumor may appear completely radiolucent, also its’ capsule can contain fine (snowflakes) calcification structures, which helps to differentiate the adenomatoid odontogenic tumor from the dentigerous cyst.

7. Treatment Adenomatoid odontogenic tumor is completely benign tumor because of its capsule. It is easily enucleated from the bone. It is not aggressive and the reccurency is so seldom.
