Aims: The purpose of this study was to investigate the demographic, clinicopathologic and imaging features of dentigerous cysts (DCs) and to review the literature. Materials and Methods: In this study, between 2010 and 2012, we analyzed 18 DCs of 18 patients (9 female, 9 male) whose ages ranged from 13 to 61. Results: Of the 18 DCs, 33% were found in the maxilla and 67% in the mandible. The most common site for DC was the mandibular molar region, and the most frequently involved tooth was the mandibular third molar. About 67% of the cases were found in the right side and 33% in the left side of the jaws. In the 67% of cases, displacement was observed in the involved tooth and/or adjacent teeth. 44% of the DCs partially surrounded the crown (lateral variety) and 56% surrounded the crown of the tooth (central variety). About 39% of cases had symptoms such as pain, swelling and drainage. 6% of the cases were infected, and resorption in the involved tooth was detected. 6% of the cases, DC caused devitalization of the adjacent tooth. Conclusions: The results of this study showed that DCs occurred most frequently in the posterior region of the mandible and related to third molar tooth. The cysts had a tendency to displace associated and/or adjacent teeth. Panoramic radiography is important in finding out these cysts. Computed tomography is recommended for differential diagnosis, expansion and association with neighboring anatomical structures.
