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.
METHOD AND MATERIALS: 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.
CONCLUSION: This study
indicates that there are some geographic differences with regard
to the relative frequency, sex, and anatomic distributions of
