Odontogenic and nonodontogenic cysts in Istanbul: Analysis of 5088 cases

Background The aim of this study was to determine the prevalence of 5088 odontogenic and nonodontogenic cysts over a 40-year period in the Turkish population and to compare results with findings in the literature. Methods The records of odontogenic and nonodontogenic cysts, occurring during 1971 to 2010, were collected and analyzed for anatomic site, age range, and sex distribution. Results Among 5088 odontogenic and nonodontogenic cyst biopsies, 5003 cases (98.3%) were classified as odontogenic, whereas only 85 cases (1.7%) were nonodontogenic. In the former group, the most frequent diagnosis was radicular cyst (52.09%), followed by odontogenic keratocyst (20.6%) and dentigerous cyst (10.39%). Maxilla to mandible ratio was 1.13:1. The mean age of patients was 36.33 years (range, 287 years). The cysts were slightly more prevalent among male patients (57.70%). Conclusions The knowledge of the biological behavior and clinicopathologic features of jaw cysts constitute key aspects to provide early diagnosis and adequate surgery.
