Abstract
The purpose of this retrospective, descriptive study was to study the prevalence, distribution, treatment modalities and recurrence rate of odontogenic keratocyst (OKC) cases from 2008 to 2019 in Faculty of Dentistry, Khon Kaen University. Prevalence and distribution of OKC were analyzed from the patients who were diagnosed histologically as OKC during 2008 to 2019 from database of the Oral Pathology Unit, Faculty of Dentistry, Khon Kaen University. The treatment modalities and recurrence rate were analyzed from treatment records of the OKC patients who were treated in Faculty of Dentistry, Khon Kaen University. The Results from 187 cysts in 169 patients showed the prevalence of OKC was 15.4 % of all odontogenic cyst. OKCs occurred predominantly in female (54.4%) and in the second decades of life (36%). The most common site were the posterior region of mandible (49.7%). Most of the lesions were unilocular radiolucency (66.1%). Of which, 39 patients 59 cysts were treated in Faculty of Dentistry, KKU. Average follow-up period was 53 months. The overall recurrence rate was 12.3%. The recurrence occurred more frequently in OKCs that were multilocular radiolucency (16.7%) and were treated by enucleation followed by carnoy’s solution application. There was no recurrence found in patients treated by resection and enucleation followed by adjunctive measures (other than carnoy’s solution). In addition, as the overall recurrence rate in this study was relatively low, we recommend to choose the conservative treatment as much as possible to achieve the least morbidity. However, resection is recommended in syndromic OKCs patients or multiple recurrent OKC lesions. All recurrences in this study were occurred in the first 5 years after the operation. Therefore, proper treatments and long term follow up for at least 5 years are recommended
