Compound Odontoma

Definition: A benign odontogenic tumor composed of enamel, dentin, cementum, and pulp tissue, characterized by multiple tooth-like structures (denticles) within the lesion.

Radiographic Features:

  • Location: Most commonly in maxillary anterior region
  • Edge:
    • Well-defined
    • Corticated
  • Shape: Contains multiple tooth-like radiopacities (denticles)
  • Internal:
    • Mixed radiolucent/radiopaque
    • Radiopacity similar to tooth structure (enamel and dentin)
  • Number:
    • Usually single lesion
    • Multiple lesions are rare but possible

Key Diagnostic Signs:

  • Well-defined, corticated lesion containing multiple tooth-like structures
  • Often associated with an unerupted tooth

Clinical Significance:

  • Commonly impedes normal eruption of permanent teeth
  • Generally asymptomatic, often discovered on routine radiographs
  • May cause delayed tooth eruption or tooth displacement
  • Treatment typically involves surgical removal and monitoring of associated unerupted teeth

Note: Differentiation from complex odontoma is important. Compound odontomas show distinct tooth-like structures, while complex odontomas appear as a disorganized mass of dental tissues.
