Introduction. Cyst is a pathological cavity located in the bone or soft tissues within the capsular bag and filled with the contents of different composition and cohesiveness. An odontogenic cyst develops from the remains of Malassez epithelial cells, the dental lamina or the enamel organ. Odontogenic cysts are the most common cystic lesions involving the head and neck area, and they constitute an important aspect of dental practice. Aim of the study. To determine the prevalence of odontogenic cysts and to identify their clinicopathological features among patients by studying the archives of the Department of Oral Surgery Medical University of Warsaw. Material and methods. Data of odontogenic cysts diagnosed between 2011 and 2014 were collected from the files of the Oral Surgery Department, Medical University of Warsaw. Written records were imported into an electronic database. Age, gender, anatomical location of the lesion and histological diagnosis were assessed. Results. Of the 400 histopathological examination reports, 272 cases (68%) were odontogenic cysts, 113 cases (28.25%) were mucocele and 15 cases (3.75%) were other lesions. The most frequently encountered lesion was inflammatory cyst (90%) including radicular cyst (48%), followed by dentigerous cyst (6%). The patients’ age ranged from 10 to 82 years with a mean of 44 years. There was barely any prevalence of gender. Conclusions. The prevalence of odontogenic cysts was similar to that reported in the literature. Inflammatory cysts including radicular cysts were identified as the most frequent ones.
