Frequency of Different Odontogenic Cysts in Patients Visiting Oral Maxillofacial Department of Dental Hospitals in Peshawar

Abstract

Background and Objective:The aim of this study was to investigate the relative frequency of odontogenic cysts in two local dental college hospitals.Methodology:In this study 90 cysts from both jaws, treated at Khyber College of Dentistry and Sardar Begum Dental College from March 2008 to March 2013 were analyzed in order to evaluate the incidence of these cysts.Results:Case history of 52 males and 38 females were analyzed. The age of patients varied from 07 to 70 years, with a mean age of 26.4±13.89. In this 5-year study of odontogenic cysts, 48 were radicular cysts, 22 were odontogenic keratocysts and 20 were dentigerous cysts. Out of these 46 cysts were present in the maxilla and 44 in the mandible. In the maxilla 46.7%were present in the anterior maxilla and 4.4% in the posterior maxilla. In the mandible 35.6% were present in the posterior mandible and 13.3% in the anterior mandible.Conclusion:From the findings of this study we conclude that odontogenic cysts were mostly inflammatory in nature i.e. the radicular cysts and was followed by odontogenic keratocysts. Majority of the cysts were located in the anterior maxilla and posterior mandible regions. The male predilection was higher as compared to females.

“…However, 2 radicular cysts were lined by keratinized epithelium. 16 In another study with large sample of RCs (n=232) mean age of patients was 40.5 years, further it was observed that 98.2 % cysts were lined by nonkeratinized stratified squamous epithelium and only 0.9% lining of RCs were of mucoepidermoid type and 0.9% of respiratory epithelium. 17 In the present study most cases of OKCs were lined by keratinized epithelium with 38.5% hyperplasia, 46 % spongiosis and 7.7% acantholysis.…”
