Prevalence and Distribution of Odontogenic Cyst in Indian Population: A 10 Year Retrospective Study

Abstract

The purpose of this study is to determine the prevalence of odontogenic cyst in an Indian population and compare it with various reports from the other geographic areas of the world. The files on odontogenic jaw cysts treated between 2001 and 2011 at the oral and maxillofacial surgery unit were retrieved retrospectively. Patient's demographic information mainly age, sex and location of the lesion was recorded and analyzed using descriptive statistics. The diagnosis of odontogenic cyst accounted in 150 cases and accounted for 15.31 % of all lesions biopsied throughout the period. Mean age of the patient was 32.2 years, and 58 % were males. The overall male to female ratio was 1.38:1. Radicular cyst was most prevalent histological type (48.67 %) followed by dentigerous cyst, odontogenic keratocyst, lateral periodontal cyst, paradental cyst, residual cyst, adult gingival cyst, glandular odontogenic cyst, calcifying odontogenic cyst. The most common locations of the odontogenic cysts were the mandibular (49.33 %) and posterior region (33.33 %). The distribution pattern of odontogenic cyst in this study is relatively similar to that in other parts of the world but there are some geographic differences with regard to the relative frequency, sex, and anatomic distribution of the odontogenic cyst.

Prevalence of Odontogenic Cysts and Tumors in Kancheepuram District, Chennai, Tamil Nadu: A Retrospective Study of 158 Cases

“…The mean age for odontogenic cysts in the present study was 34.5 yrs and for odontogenic tumours was 29.5 yrs and results were in accordance to studies conducted in Thailand(34.6), Iran(OC-27.8,OT-23.9) UAE (OC-35) Sri Lanka (OC-30.6) Bhopal (India OC-33.2) [1,2,3,7] www.wjpr.net Vol 6, Issue 10, 2017. 555…”

“…The frequency of odontogenic cyst encountered in our study was highest for Radicular cyst (48.8%) followed by okc (25.9%), dentigerous cyst (16.2%) this was in agreement with studies conducted in UAE (RC-69.1%), [6] Karachi (OC-53%), [5] (Bhopal) India (RC-56.6%), [2] however differing results were published by the studies conducted in Iran [4] and Andhra Pradesh [8] with the commonest cyst for both being dentigerous cyst (27.2%, 68.4% respectively). In the present study, frequency of ameloblastoma amongst the OTs was highest (69.5%) followed by odontoma which accounted for 17.3% of all lesions.…”

“…These values were similar to the studies conducted in Iran, Andhra Pradesh (OC-73% in males) UAE, (Bhopal) India (OC-58% in males). [2,4,7,8] However the odontogenic tumors in our study showed a slight female predilection (56.5%)…”

“…[ The incidence was similar to studies conducted in Iran (OC-16.9%, OT-2.6%), Sri Lanka (OT-3.8%), India Bhopal (15.4% OC), Pakistan (OT-3.5%), and China (OT-2.4%). [2,3,4,5,6] Studies conducted in UAE and Thailand [4,6] showed higher incidence of odontogenic cysts and tumors.…”

“…[10] The most prevalent site for Radicular cyst in our study was anterior maxilla, on the contrary it was posterior mandible for rest of the cysts which coincided with results obtained from studies conducted in Iran [4] , Bhopal. [2] On the contrary only Karachi [5] had greater prevalence of Radicular cyst in the mandible. The most prevalent site for Ameloblastoma in our study was posterior mandible which was coherent with studies conducted in Andhra Pradesh [10] ,Thailand [1] , Iran [4] , UAE [7] , Karachi [5] , Sri Lanka [3] , Chennai [9] , China.…”
