Study Notes
Odontogenic Tumors
- Odontogenic tumors originate from the cells of the odontogenic apparatus
- These include:
- Epithelial rests of Serres
- Reduced enamel epithelium
- Epithelial root sheath of Hertwig
- Epithelial rests of Malassez
- Tumors can also arise from the mesenchymal parts of the odontogenic apparatus, the dental sac, or dental papilla
- Tumours can also originate from both epithelial and mesenchymal components
- Odontogenic tumors are categorized based on their cell of origin into:
- I Epithelial Odontogenic Tumors
- Simple ameloblastoma
- Adenomatoid odontogenic tumor
- Calcifying epithelial odontogenic tumor
- II Connective Tissue Odontogenic Tumors
- Odontogenic fibroma
- Odontogenic myxoma
- Cementoblastoma
- Periapical cemental dysplasia
- Gigantiform cementoma
- Dentinoma
- III Mixed Odontogenic Tumors
- Ameloblastic fibroma
- Ameloblastic fibro-odontoma
- Odontoma (complex and compound)
- I Epithelial Odontogenic Tumors
Simple Ameloblastoma
- Definition: A locally aggressive, benign epithelial neoplasm of odontogenic origin
- Histogenesis: Arises from:
- Remnants of dental lamina (rests of Serres)
- Reduced enamel epithelium
- rests of Malassez
- It constitutes 1% of oral neoplasms
- Clinically, it commonly affects individuals aged 20-40, with no significant gender preferences.
- It commonly manifests in the mandible or molar areas, with the peripheral lesions being less aggressive than central ones
- The tumor is slow-growing and locally aggressive
- It expands bony cortices, causing large facial deformities
- It often shows "eggshell cracking" when palpated
- Radiographically: presents as a unilocular or multilocular, irregular radiolucent area resembling a "soap bubble" or "honeycomb"
Adenomatoid Odontogenic Tumor (AOT)
- Definition: A well-circumscribed benign epithelial odontogenic tumor
- Histogenesis: Likely originates from reduced enamel epithelium
- Clinically: Usually affects adolescents (14-15 years old) more often in females
- It often presents with painless swelling in the anterior maxillary area (usually near the impacted canine)
- Radiographically: Often unilocular with well-defined borders, sometimes including a tooth. May contain flecks of radiopacities.
- Radiographically: It is typically unilocular with well-corticated borders and might contain a tooth. Most lesions are radiolucent, but some may have faint flecks of radiopacities. They often surround the crown of an impacted tooth
Calcifying Epithelial Odontogenic Tumor (CEOT)
- Definition: A locally aggressive epithelial odontogenic tumor that can occur centrally (intraosseous) or peripherally (extraosseous)
- Histogenesis: Originates from epithelial rests of dental lamina and the reduced enamel epithelium
- Clinically: Affects individuals between 20 and 60 years of age, with no significant gender preferences. Most commonly manifests in the mandible, molar area
- Clinically, It presents a slowly enlarging and painless mass. Peripherally, it appears as a superficial, soft tissue swelling on the gingiva
- Radiographically: Small unilocular radiolucency with possible flecks of calcified structures (radiopacities)
- Histopathologically: Composed of polyhedral epithelial cells exhibiting pleomorphism, hyperchromatism, and prominent nucleoli with eosinophilic cytoplasm. Often contains areas of homogenous hyaline eosinophilic material between epithelial sheets and may have diffuse spherical calcifications.
Odontogenic Fibroma
- Definition: A benign fibroblastic odontogenic neoplasm
- Clinically: The peripheral form shows as a growth (typically normal color on the gingiva), while ulceration can cause erythema.
- Clinically: The central form is asymptomatic and painless, common in the mandible.
- Radiographically (Peripheral): Negative, as it's primarily in soft tissue.
- Radiographically (Central): Unilocular and well circumscribed radiolucent area
Odontogenic Myxoma
- Definition: An aggressive lesion originating from odontogenic connective tissue, characterized by a mucoid ground substance, and undifferentiated mesenchymal cells.
- Clinically: Affects young people and presents as painless, slow-growing swellings that might displace teeth. It often locates in the mandible or maxilla
- Radiographically: Large lesions are typically multilocular radiolucent with an "honeycomb" or "soap bubble" appearance. Ill-defined radiolucencies are commonly present
Cementoblastoma
- Definition: A true neoplasm growing from the cementum layer of a molar or premolar
- Clinically: Often painful, with pain worsening during palpation. Frequent in the mandibular molar or premolar area
- Radiographically: Primarily radiolucent, but may include partly radiopaque areas with a surrounding zone of radiolucency..
- Histology: Characterized by a deposition of unmineralized eosinophilic matrix with cementoblasts connected to normal cementum
Periapical Cemental Dysplasia
- Definition: A developmental dysplastic disturbance of cementum
- Site: Mandibular incisor region, usually affecting multiple teeth.
- Usually fibroblastic in its early stages, progressing with cementum-like tissue interspersed with woven bone..
- Radiographically: Early lesions show ill-defined radiolucencies near the apices; later stages reveal radiopaque masses. (osteolytic or cementoblastic stage)
- Clinical: May be asymptomatic or mildly painful
Gigantiform Cementoma
- Definition: A familial osseous dysplastic disturbance of cementum
- Radiographically: Distinct, dense radiopaque masses (often lobulated)
- Histologically: Large tissue sheets resembling secondary cementum. Empty lacunae, and few vascular channels.
- Clinically: Often involves multiple teeth in a bilateral and symmetrical pattern.
Dentinoma
- Definition: A rare lesion composed entirely of dentin and dentin tubules
Mixed Odontogenic Tumors
- Definition: Lesions originating from both epithelial and connective tissue odontogenic elements.
Odontoma
- Definition: A hamartomatous lesion (not a neoplasm), frequently found in unerupted teeth, comprising enamel, dentin, pulp, and cementum in recognizable or non-recognizable tooth forms.
- Clinically: Usually presents with painless swelling; often appearing in the maxilla during the first two decades, with less frequency in the mandible
- Radiographically: Often unilocular with multiple radiopaque masses
- Histology: Enamel, dentin, and pulp tissue structures within a surrounding capsule. Complex odontomas show disorganised patterns, lacking typical tooth shapes. Additional information regarding compound and complex odontoma structures have been included.
