What is Diagnosis?

A 13-year-old boy with Class III malocclusion returns with mother from an orthodontic office for extraction of the tooth H with panoramic X-ray taken last year (Fig.1).  An interesting finding was present, but not diagnosed a year earlier (Fig.2).

A cystic lesion around each of the impacted permanent upper canines.  A normal dental sac or dentigerous cyst?

Discussion over Weichat indicates that there is no need to differentiate them.  Both need retraction.  Everything will be alright.
