    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.
