Study Notes
Odontogenic Tumors
Odontoma
- Most common odontogenic tumor
- Benign, non-aggressive
- Composed of enamel, dentin, cementum, and pulp tissue
- Can be compound (multiple small teeth) or complex (single, irregular mass)
- Typically asymptomatic, discovered on routine radiographs
- Treatment: surgical removal, usually curative
Ameloblastoma
- Second most common odontogenic tumor
- Benign, but locally aggressive
- Arises from ameloblasts (tooth-forming cells)
- Can be solid or cystic, often with a mix of both
- Typically occurs in the mandible, often in the molar-ramus area
- Symptoms: swelling, pain, tooth mobility, and displacement
- Treatment: surgical removal, may require extensive resection
Cementoblastoma
- Rare, benign tumor
- Arises from cementoblasts (cementum-forming cells)
- Typically occurs in the root of a tooth, often in the mandible
- Radiographically, appears as a radiolucent lesion with a radiopaque center
- Symptoms: swelling, pain, tooth mobility, and sensitivity
- Treatment: surgical removal, including the associated tooth
Keratocystic Odontogenic Tumor (KCOT)
- Also known as odontogenic keratocyst
- Benign, but locally aggressive and prone to recurrence
- Arises from the dental lamina or dental follicle
- Can be uni- or multi-locular, often with a cystic appearance
- Typically occurs in the mandible, often in the molar-ramus area
- Symptoms: swelling, pain, tooth mobility, and displacement
- Treatment: surgical removal, often with adjunctive therapies (e.g., Carnoy's solution)
Adenomatoid Odontogenic Tumor (AOT)
- Rare, benign tumor
- Arises from the dental lamina or dental follicle
- Typically occurs in the maxilla, often in the incisor-canine area
- Radiographically, appears as a well-defined radiolucency
- Symptoms: swelling, pain, tooth mobility, and displacement
- Treatment: surgical removal, often with preservation of adjacent teeth
