Aims and Objectives: The purpose of this study is to analyze and report the prevalence, frequency, sex distribution, site distribution, and clinicopathological features of odontogenic cysts in an institutional academic dental hospital by studying the biopsy specimens and clinical records obtained from the archives of the Department of Oral and Maxillofacial Surgery and Department of Pathology, AMU, Aligarh, India, during the past 10 years. Materials and Methods: Data on odontogenic jaw cysts treated between 2009 and 2018 were retrieved from clinical files; imaging and histopathology reports and a total of 847 patients were included. In each case, we analyzed age, gender, type and number of cysts, and cyst location. Imaging characteristics and pathologies associated with cystic lesions were also determined. Results: Diagnosis of odontogenic cyst was made in 847 cases and accounted for 10.9% of all lesions biopsied (7748) throughout the period. Mean age of the patient was 28.2 years, and 57.3% were males. The overall male to female ratio was 1.34:1. Radicular cyst was most prevalent histological type (54.54%) followed by dentigerous cyst, odontogenic keratocyst, lateral periodontal cyst, residual cyst, botyroid odontogenic cyst, gingival cyst. The distribution of cysts was nearly equal in the mandible (51.6%) and maxilla (48.4%) with the cysts most commonly located in anterior maxilla and posterior mandible. The most prevalent radiological feature of these lesions was unilocular cyst (88.78%). Associated pathologies with cystic lesions such as displacement and resorption of teeth occurred in 14.7%. Conclusions: This study revealed that prevalence, distribution, and characteristics of odontogenic cysts of oral cavity and jaws in the North Indian population, have some differences as well as similarities with the findings of studies in different populations.
