Statement of Problem: Odontogenic cysts and tumors are lesions that are found exclusively in the mandible and maxilla. These lesions are one of the main causes of jaw destruction. But unfortunately only a few studies have been conducted in Iran on relative frequency of these lesions.
Purpose: The aim of this study was to determine the relative prevalence of odontogenic cysts and tumors in Kerman province along with age, sex and site of presentation over a 12-year period and to compare it with previous reports from different parts of the world.
Materials and Method: This research reviewed 1320 biopsies in a 10- year period. Data on factors such as age, sex and location of the lesions were extracted from pathology reports and analyzed by SPSS statistical software.
Results: Of 1320 specimens, 221 were diagnosed as odontogenic cysts and 24 biopsies were diagnosed as odontogenic tumors. Odontogenic cysts and tumors occurred most frequently in the first to second decades of life and most commonly in the mandible. Cysts were more common in men than women. Radicular cysts were the most common ones (33.9%), followed by dentigerous cysts (21.7%) and odontogenic keratocyst (15.4%). The most prevalent odontogenic tumor was ameloblastoma (41.4%).
Conclusion: Our study provides demographic data on odontogenic cysts and tumors in Kerman province. Odontogenic cysts have a predilection for certain ages, sexes and sites. To determine the real relative frequency of odontogenic tumors, further studies should be conducted, especially in Iran, by experienced pathologists in the field of odontogenic tumors.
