A compound odontoma is best described radiographically as:

Correct answer: B. Multiple small tooth-like radio-opaque structures

• A. A multilocular radiolucency describes lesions like ameloblastoma — not odontoma.
• B. Correct. A compound odontoma contains multiple small, discrete tooth-like structures (denticles) arranged in an orderly fashion and appears as multiple recognizable tooth-like opacities on radiograph. This distinguishes it from complex odontoma (irregular calcified mass).
• C. A unilocular radiolucency with scalloped borders describes a traumatic bone cyst or keratocystic odontogenic tumor — not odontoma.
• D. Odontomas have well-defined borders — they are not diffuse.
