Abstract

Dentigerous cyst surrounding an impacted tooth is originated from reduced enamel epithelium. Generally; this cyst does not cause pain. In case of a large or infected one; however; swelling and pain can be developed. Pathology of a cyst involved in maxillary sinus is diverse. Caldwell-Luc approach is recommended generally. To prevent recurrence and gain a good prognosis; cystic and necrotic tissues must be enucleated completely. A 22 year-old female with facial swelling was referred to our department. CT and MR image revealed a huge radiolucency surrounding right maxillary third molar. Under general anesthesia; a cyst was enucleated by Caldwell-Luc approach. It was diagnosed as a dentigerous cyst after biopsy. Post operative condition of the patient has been good for 8 months since operation. So; we represent the case with the literature review.
