Prevalence and Distribution of Odontogenic Cysts in Kashmiri Population: A Retrospective Clinical Study of 152 Cases

Abstract

Background:The main purpose of this study was to determine the prevalence of odontogenic cysts in Kashmiri population. Methods: The data on odontogenic cysts (OCs) treated in the department of Oral and Maxillofacial Surgery Government Dental College Srinagar from January 2011 to December 2016 was collected retrospectively. The information regarding patient's age, sex, location of the cyst and the type of the odontogenic cyst was recorded and analysis was done using descriptive statistics. Results: A total of 152 OCs were identified out of which 87 were male and 65 female with male to female ratio of 1.3:1. The OCs were seen to predominate in the second, third and fourth decades of life, the most common anatomic location being the mandibular posterior region (40.8%). Radicular cyst dominated among the OCs (50.6 %) followed by dentigerous cyst (23%), odontogenic keratocyst (10.5%), residual cyst (8.6 %), lateral periodontal cyst (5.3 %) and paradental cyst (1.9 %). Radicular cysts most frequently involved the maxillary anterior region (33.8%) while as dentigerous cysts and odontogenic keratocysts were more common in the man-dibular posterior region (54.3% and 56.3% respectively). Conclusion: Radicular cyst and dentigerous cyst are the most prevalent odontogenic cysts in Kashmiri population; etiology being the dental decay (pulpal necrosis) and impacted teeth. In order to decrease the prevalence of radicular and dentigerous cysts, preventive measures need to be taken to diminish dental decay and programs of prophylactic extractions of impacted teeth need to be established.
