Retrospective Clinic-pathological Study of 106 Odontogenic Cyst among Kashmiri Population

Introduction. The human jaw bones, main hard tissue of orofacial region can be the sites for development of various conditions such as cysts, neoplasms, or systemic bone diseases. The purpose of the study was to establish the epidemiological profile, according to the variables of sex, age group and anatomic location of odontogenic cysts among the Kashmiri population. Materials and methods. In this study 706 biopsies, diagnosed during a 7-year period from 2010 to 2017, were analysed in order to evaluate the prevalance of odontogenic cysts. Clinical features obtained from the patient records and microscopic slides were reviewed according to the 2005 World Health Organization classification. Results. In this 7-year study, 106 cases were diagnosed as odontogenic cysts with the overall prevalence of 13.9%. The prevalence of radicular cyst was 58.4%, dentigerous cyst (22.6%), odontogenic keratocyst (10.3%), calcifying odontogenic cyst (0.009%), lateral periodontal cyst (0.04%) and residual cyst (0.02%). Fifty six percentage of odontogenic cyst were observed in males and 43.3% were seen in females, with a female: male ratio of 1:1.3. Majority of the cases showed prevalence in the third, fourth and fifth decades. Mandible, particularly the posterior region (40.5%), followed by the posterior region of the maxilla (28.3%) were most common anatomic sites of the odontogenic cyst. Conclusion: The present study showed more prevalence of radicular cysts, dentigerous cysts, and odontogenic keratocysts in Kashmir valley.
