Prevalence of odontogenic cysts in patients visiting a tertiary Dental Care Hospital in North India- An 8 year experience

Abstract

Aims and Objectives: The present study aims at evaluation of age, sex and site of occurrence related prevalence of Radicular cyst, Dentigerous cyst, Odontogenic keratocyst (OKC), Lateral Periodontal cyst, Residual cyst, Adult Gingival cyst, Calcifying odontogenic cysts. Materials and Methods: During 8 year period (From 2010 to 2017), 1000 patients with cystic lesions of the jaws were analysed. All patients underwent clinical examination and plain film radiography (panoramic, periapical, and occlusal views). Some of them were referred for CBCT or computed tomography (CT) with a multiplanar reconstruction program (MPR). Age, sex, type of cyst and location were recorded in designed performa. The treatment modalities used for the management of cysts are marsupialization, enucleation, enucleation with bone grafting or resection under local or general anaesthesia depending on the case. Results: Radicular cyst(45.2%) is most common cyst followed by dentigerous cyst(23.2%),Odontogenic keratocyst (13.4%), lateral periodontal cyst(8.9%), residual cyst(4.5%),Calcifying odontogenic cyst (4.4%) followed by the least common occurring adult gingival cyst (1.1%). The mandibular posterior region (41.3%) is most predilected site of occurrence of cysts in orofacial region however maxillary anterior region (17.7%) is least predilected site of occurrence. Conclusion: The radicular cyst is most common cyst of oral cavity while adult gingival cyst is least common cyst. Keywords: Cyst, Jaw bone, Prevalence, Odontogenic, Nonodontogenic.
