• A hamartomatous or benign mixed odontogenic tumor of the jaw

• Composed of enamel, dentin, cementum, and pulp tissue

Clinical Presentation

• Two forms, as follows:

• Complex: a randomly arrayed mixture of dental tissues with no gross resemblance to a tooth 

• Compound: multiple, tooth-like structures

• Mean age of occurrence, 12 to 16 years

• Asymptomatic, usually small and discovered incidentally

• Jaw expansion may be present with large lesions.
