Study Notes
Odontogenic Tumors
- Odontogenic tumors characterized by odontogenic epithelium with mature fibrous stroma, without odontogenic mesenchyme are classified as Ameloblastomas.
Ameloblastoma
- Ameloblastoma is the most common clinically significant odontogenic tumor.
- The multicystic variant of Ameloblastoma is characterized by multiple cystic spaces intra-osseously.
- Peripheral (extraosseous) Ameloblastoma originates from the histogenesis of the gingiva or mucosa.
- The most common age range for the occurrence of Ameloblastoma is between 30-50 years.
- Ameloblastoma is most commonly associated with the black race.
- The most common site for Ameloblastoma to occur is the mandible, especially in the molar-ramus area.
- The most common histological pattern seen in Ameloblastoma is the follicular pattern.
- The acanthomatous variant of Ameloblastoma may show squamous metaplasia.
- The plexiform variant of Ameloblastoma may exhibit cystic degeneration affecting stellate reticulum-like cells.
- Enucleation with thorough curettage is recommended for Ameloblastoma to prevent recurrence.
Unicystic Ameloblastoma
- Unicystic Ameloblastoma refers to a type of Ameloblastoma that involves a single cystic space.
- The intraluminal variant of Unicystic Ameloblastoma involves infiltration of the fibrous wall by Ameloblastoma cells.
Other Odontogenic Tumors
- Odontogenic tumors characterized by odontogenic mesenchyme with epithelial rests are classified as Odontogenic Hamartomas.
- The classification of odontogenic tumors that includes odontogenic epithelium with odontogenic mesenchyme is called Odontogenic Tumors with Odontogenic Mesenchyme.
