Presentation of case A 64-year-old male patient presented with a progressive mandibular expansion and associated pain as a chief complaint. The oral examination revealed a swelling in the anterior portion of mandible with buccal plate expansion. The radiographic and histopathologic features were consistent with the diagnosis of dentigerous cyst. Consequently, the lesion was surgically removed, and no clinical or radiological recurrence was detected during 12 months post-operative follow-up.
