| Popis: | Introduction: Tumours arising from odontogenic tissues are rare and constitute a heterogeneous group of interesting lesions. Studies on incidence of Odontogenic Tumours (OT) published from many countries show a distinct geographic variation. Aim: The aim of present study was to compare and correlate the frequency of individual OT in India as well as the other parts of the world based on 2005 World Health Organisation (WHO) classification. Materials and Methods: This Institution-based retrospective study conducted in Department of Oral Pathology and Microbiology at Government Dental College and Research Institute, Bengaluru, Karnataka, India, from April 2015 to September 2016. Total of 122 cases of odontogenic tumours documented in duration of 10 years (2005 to 2014) were categorised based on WHO 2005 classification. The histological type, age, gender, anatomical site and symptoms were systematically tabulated. Results: Odontogenic tumours constituted 9.5% (122 cases) of the total oral biopsies (1284 cases) received in a 10-year period. Among these, 95.9% of the tumours were benign and 4.1% were malignant. The most frequent tumour being ameloblastomas 39.3% followed by keratocystic odontogenic tumour 35.2%, odontome 4.9%, calcifying cystic odontogenic tumour 4.9% and adenomatoid odontogenic tumour 4%. While odontome, generally regarded as the most frequent OT in American and European countries, only accounted for 4.9%, the third most common tumour in the present study. The mean age of patients was 32.37 years (range: 9-70 years). Their exist a slight male predominance, more predilection to posterior region of mandible and majority of tumours presented with pain and swelling. Conclusion: The relative frequency of odontogenic tumours reported in our Institution was similar to the studies reported in India, Asian and African population, but differs from that of European and American countries. There is a definite geographic variation in the prevalence of OT published worldwide. |
