A study of 1177 odontogenic lesions in a South Kerala population.

CONTEXT

A study on odontogenic cysts and tumors.

AIMS

The aim of this study is to determine the frequency of odontogenic cysts and tumors and their distribution according to age, gender, site and histopathologic types of those reported over a period of 1998-2012 in a Tertiary Health Care Center at South Kerala.

SETTINGS AND DESIGN

The archives of Department of Oral Pathology and Microbiology, were retrospectively analyzed.

SUBJECTS AND METHODS

Archival records were reviewed and all the cases of odontogenic cysts and tumors were retrieved from 1998 to 2012.

STATISTICAL ANALYSIS USED

Descriptive statistical analysis was performed using the computer software, Statistical Package for Social Sciences (SPSS) IBM SPSS Software version 16.

RESULTS

Of 7117 oral biopsies, 4.29% were odontogenic tumors. Ameloblastoma was the most common odontogenic tumor comprising 50.2% of cases, followed by keratocystic odontogenic tumor (24.3%). These tumors showed a male predilection (1.19: 1). Odontogenic tumors occurred in a mean age of 33.7 ± 16.8 years. Mandible was the most common jaw affected (76.07%). Odontogenic cysts constituted 12.25% of all oral biopsies. Radicular cyst comprised 75.11% of odontogenic cysts followed by dentigerous cyst (17.2%).

CONCLUSIONS

This study showed similar as well as contradictory results compared to other studies, probably due to geographical and ethnic variations which is yet to be corroborated.
