Study Notes
Odontogenic Tumors
Ameloblastoma
- Definition: A benign, slow-growing, and locally invasive tumor that arises from the epithelial component of the tooth-forming tissues.
-
Epidemiology:
- Most common odontogenic tumor (70-80% of all cases)
- Peak incidence in 3rd-4th decades of life
- Male:Female ratio is 1:1
-
Clinical Features:
- Painless swelling in the jawbone
- May cause tooth displacement or resorption
- Radiolucent lesion with well-defined borders
-
Histopathology:
- Characterized by follicular or plexiform patterns
- Tumor cells resemble ameloblasts (tooth-forming cells)
- Treatment: Enucleation or surgical excision with a margin of healthy bone
Adenomatoid Odontogenic Tumor (AOT)
- Definition: A rare, benign, and non-invasive tumor that arises from the epithelial component of the tooth-forming tissues.
-
Epidemiology:
- Accounts for 3-5% of all odontogenic tumors
- Peak incidence in 2nd-3rd decades of life
- Female predilection (2:1 female: male ratio)
-
Clinical Features:
- Asymptomatic swelling in the anterior maxilla
- Radiolucent lesion with well-defined borders
- May cause tooth displacement or root resorption
-
Histopathology:
- Characterized by duct-like structures and tubules
- Tumor cells resemble ameloblasts
- Treatment: Enucleation or surgical excision with a minimal margin of healthy bone
