Study Notes
Ameloblastic Fibroma (AF)
- Benign odontogenic tumor; lacks hard dental tissue.
- Primarily affects individuals in their 20s.
- Characterized by pain-free, slow-growing swelling, often near missing teeth.
- Common locations: posterior mandible and maxilla.
- Radiographically: multilocular, smooth borders, radiolucent with internal septa, expands the jaw.
Ameloblastic Fibrodentinoma (AFD) & Ameloblastic Fibro-odontome (AFO)
- Previously separate, now classified as developing odontomes.
- AFD: Contains dentin.
- AFO: Includes enamel and dentin.
- Often predominantly soft tissue.
Adenomatoid Odontogenic Tumor (AOT)
- Benign, slow-growing tumor resembling a glandular adenoma.
- Typically arises in the anterior maxilla, often affecting unerupted canines, during the 20s.
- Non-infiltrative, causing painless cortical expansion.
- Radiographically: initially radiolucent, developing calcifications; unilocular.
Calcifying Odontogenic Cyst/Tumor (COC)
- Exists in cystic and solid forms.
- Affects individuals of various ages.
- Commonly observed in the maxilla or mandible, often related to unerupted teeth.
- Typically small (~4 cm).
- Characterized by developing internal calcifications (radiopaque areas).
- Radiographically, initially radiolucent, then showing internal calcifications.
- Notable feature: presence of "ghost cells" (flattened epithelial cells).
Odontome (Odontoma)
- Common benign malformation of teeth, the most differentiated odontogenic tumor.
- Shows perfect histodifferentiation (distinct tissue layers), with variable morphodifferentiation (shape/form).
- Forms tooth-like structures or disorganised dental tissues; well-mineralised.
- Can cause jaw expansion if large.
- Easily treatable in early stages with surgical procedures.
Odontoma Types
- Complex Odontome: disorganised mass of enamel, dentin, and pulp, radiolucent early and becoming radiopaque.
- Compound Odontome: cluster of small tooth-like structures; contains pulp, odontoblasts, dentin, and enamel.
Developing Odontomes
- Previously called ameloblastic fibrodentinoma or fibro-odontoma.
- Characterized by incomplete maturation/mineralisation.
