Which radiographic finding is associated with dentigerous cyst?

Radiolucency attaches to CEJ of an unerupted tooth
Multilocular radiolucency with soap bubble appearance
Radiopaque mass within a radiolucent border
Periapical radiolucency at root apex

Show answer and explanation

Correct answer: A. Radiolucency attaches to CEJ of an unerupted tooth

A dentigerous (follicular) cyst characteristically presents as a well-defined radiolucency that cleanly attaches to the cementoenamel junction (CEJ) of an unerupted tooth, surrounding the crown. This attachment to the CEJ is nearly pathognomonic for dentigerous cyst.
