Prevalence, Characteristics and Distribution of Odontogenic Cysts amongst the Indian Subpopulation of Southern Rajasthan: A 5-year Retrospective Study of 218 Cysts.

Abstract

Odontogenic cysts (OCs) arise from the odontogenic epithelium and occur in the tooth-bearing regions of the jaws. Proliferation and/or degeneration of this epithelium lead to OC development. The purpose of this study was to determine the prevalence, characteristics, distribution and clinicopathological features of OCs and compare with other studies. Records of OCs were retrieved, and patient's data, aetiology, clinical features, histopathological distribution, treatment, complications and recurrence were studied. A total of 218 OCs were studied in 200 patients. The mean age of patients was 35.74 years. The overall sex ratio (male: female) was 1.22:1. Second, third and fourth decades of life were commonly affected. The majority of the patients (85%) reported with a complaint of pain (with or without swelling). Radicular cyst was the most prevalent type (49.55%). The most common site involved was the anterior maxilla (41.75%). Dental complications such as displacement, mobility, discoloration and root resorption were diagnosed in 91 cysts (41.75%). Bony complications such as expansion and perforation were present in 136 cysts (62.38%). Dentition was non-vital in 61.46% of cysts. The most common treatment method performed was combination surgery (enucleation with or without endodontic treatment/extraction and apicoectomy). Recurrence rate was 3.20%. The prevalence, characteristics and distribution features of OCs in India are similar to those of studies conducted in other parts of the world. There is a broad spectrum of OCs, with some cysts having a propensity for certain age, gender and site, whereas a few cysts have distinct properties to recur and have aggressive and invasive behaviour.
