Abstract

The Odontogenic Keratocysts (OKC) are epithelial developmental cysts of the jaws with a higher frequency of recurrences due to the incomplete removal of the cyst, difficulty in access to the lesion locations or eruption of the new cyst in the place. The objective of the present study was to determine the frequency of OKC post-operative recurrences and the possible affective factors in patients referred to Dr. Shariati Hospital and Tehran Dental School during 1996-2006. In this retrospective descriptive study, 209 patients (61.2% males, 38.8% females) were selected by census sampling and assessed. Different characteristics of the OKC lesions were obtained from the patient’s records or calling them. The effect of possible variables on the incidence of recurrence was statistically analyzed by Cox regression and the survival rate of the patients was determined by Kaplan-Meier test. The mean age of OKC involvement was 34.5 years and the most frequencies were observed in the third (62, 29.7%), fifth (40, 19.1%) and second (32, 15.3%) decades of the life. The most frequent OKC locations were mandibular (136, 65%), mandibular posterior (98, 46.9%), maxillary posterior (28, 13.4%) and maxillary anterios (12, 5.7%). Enucleation (202, 96.7%), curettage (76, 36.4%) and peripheral ostectomy (75, 35.9%) were the mostly used surgery techniques. Of the total patients, 37 individuals (17.7%) showed OKC recurrences after initial surgery, of which 14 cases (37.8%) occurred in the mandibular posterior and 6 cases (16.2%) in the maxillary posterior. Most cases had recurrences 12 months after the initial surgery (13, 35.1%). Aggressive curettage was statistically associated with the decreased recurrences while the gender, age, lesion location and other surgeries were not statistically associated with the recurrence incidence. The recurrence ratio of 17.7% among OKC patients referred to Dr. Shariati Hospital during 1996-2006 was similar to the existing repost in the literature.
