Clinico-Radiological Study of Odontogenic Cysts in Mandibular Region from Agartala, Tripura

BACKGROUND Most common osseous destructive lesions effecting the jawbone are odontogenic cystic lesions, which are lined by epithelium, has been involved in the formation of teeth as the epithelial cell rest are present in jawbone after teeth formation. The three most common odontogenic cysts (OCs) are radicular cyst (RC), dentigerous cyst (DC) and the odontogenic keratocyst (OKC). Less common variety is the residual cyst. Odontogenic cysts are mainly developmental and inflammatory in origin. The objective of the present study was to find clinico-radiographic characteristics of odontogenic cysts in the mandible. METHODS This was a case series (descriptive) study on OCs of mandible conducted at Tripura Medical College and Dr BRAM Teaching Hospital, Hapania, Agartala, Tripura (W), India, over a period of 6 months from August 2019 to January 2020. Subjects showing clinico-radiographic features of OCs in mandible were included, subsequently confirmed by histopathological examinations. Usually orthopantomograms (OPGs) and intra oral peri apical radiograph (IOPAs) were done for radiological findings, computed tomography (CT) scan was required for examination of the size of lesion. Data were analysed using windows excel. RESULTS Diagnosis of OCs was confirmed in 20 patients, among them, males were (60 %) and female were (40 %). The age range of the patients was 17 - 65 years. Most common type of cyst diagnosed in the study was radicular cyst in 50 % cases followed by dentigerous cysts which were in 30 % cases, odontogenic keratocysts were in 15 % patients and others were 5 %. RCs were represented in higher percentage (50 %). Right side of mandible was the most effected side (60 %) than left side (40 %). Main finding of the study was, in every type of cystic lesions, males were recorded as predominant, and it occurred in early age group. CONCLUSIONS Main finding of the study was radicular cyst which was in higher percentage (50 %) and was being most common with association of carious tooth.
