INTRODUCTION True neoplasm of odontogenic epithelium Term “ Ameloblastoma” coined by Churchill –
1934. “Unicentric, nonfunctional, intermittent in
growth, anatomically benign, clinically persistent”.
2nd most common odontogenic neoplasm, & represents 1% of all oral odontogenic epithelial tumors & 11% of all odontogenic tumors.

Etiology – Varied origin cell rests of enamel organ Epithelium of odontogenic cysts Disturbances of developing enamel organ Basal cells of surface epithelium of the
jaws Heterotopic epithelium in other parts of the
body

CLINICAL FEATURES Wide age range, but uncommon in
children and adults < 20 yrs of age Posterior mandible Asymptomatic, often discovered on
routine radiographs As tumor grows, painless enlargement
may be noted
![Page 23: Ameloblastoma](https://reader036.vdocument.in/reader036/viewer/2022082219/55842c25d8b42a785e8b4e2b/html5/thumbnails/23.jpg)
RADIOLOGICAL FEATURES Unilocular radiolucency, especially early
lesions that often progress to multilocular (soap-bubble, honeycomb)
May be associated with impacted tooth Cortical expansion and thinning Resorption of adjacent tooth roots,
displacement of teeth can be seen
