•Main x-ray finding:

There is a well-defined, round-shaped unilocular mixed radiolucent/radiopaque lesion with corticated margin over right anterior mandible, extending from alveolar crest of 84 to lower border of mandible, and from 32 root apex to 45 mesial root apex, approximately 4 cm x 4cm in size. The lesion involves impacted 43,

extending to mesial root apex and disatal CEJ. Snowflake calcifications are present in the radiolucent area.
