The prevalence of inflammatory and developmental odontogenic cysts in a Jordanian population: a clinicopathologic study.
OBJECTIVE
To determine the prevalence of odontogenic jaw cysts in a Jordanian population and to compare these data with previously published reports from other geographic areas.


METHODS
The files on odontogenic jaw cysts treated between 1989 and 2001 in the Oral and Maxillofacial Pathology Diagnosis Service at the Department of Oral Medicine and Oral Surgery, Faculty of Dentistry, Jordan University of Science and Technology, were reviewed. Clinical and radiographic data were recorded and microscopic slides evaluated according to the most recent World Health Organization classification. Cases were analyzed with regard to age, sex, and anatomic site.


RESULTS
A diagnosis of odontogenic jaw cyst was established in 654 patients, with a male-to-female ratio of 1.7:1. Radicular cyst was the most common type of odontogenic cyst found (41.7%), followed by dentigerous cysts (24.8%). The peak age affected was between the third and fifth decades. Both jaws were almost equally affected. The most common anatomic site of incidence was the maxillary incisor/canine region, followed by the mandibular molar region.


CONCLUSIONS
This study indicates that there are some geographic differences with regard to the relative frequency, sex, and anatomic distributions of odontogenic cysts.
