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.

7. 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.

11. 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.
