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.
