Huge Dentigerous Cyst in the Mandible Treated under Local Anesthesia

A case of a dentigerous cyst located in the mandible of a 32year-old male was reported. The patient was consulted to our clinic with complaining discomfort in the retromolar area of the left mandible. Radiographic examination revealed regularly demarcated huge bone resorption in the left molar area. Under local anesthesia, lesion was excised and specimen was sent for pathological examination. Microscopic examination of the excised tissue showed it to be well-circumscribed with fibrous tissues, and the cystic space lined by keratinized epithelium. There was no evidence of recurrence of the cysts. The patient remained in good health during the 1 year follow-up.
