title: Epidemiological study of odontogenic tumours: An institutional experience.
abstract: Epidemiological studies on odontogenic tumours conducted in different parts of the world emphasised variation in incidence and distributional pattern. Such epidemiological studies are obscured in Southern state of Andhra Pradesh in India. Present study was conducted at an institutional setup in South Indian population to assess the demographic data of odontogenic tumours. The retrospective study, which included all the odontogenic tumours from the archives of department of oral pathology, Dental teaching and Research Institution in southern part of India. Cases were selected based on the classification of WHO 2005 histopathological typing for odontogenic tumours and the assessment year considered was from 2002 to 2014. Demographic data was analysed for these tumours. Results were analysed using Chi-Square Test. Incidence of the odontogenic tumours was found to be 2.17%. Peak age incidence was recorded highest in third and fourth decade of life. Males were commonly involved [59%] with the male to female ratio of 1.43:1. Posterior mandible [53.4%] was the chief anatomical location involved with the tumours. Considering the individual lesions, Ameloblastoma [49%] was found to be more frequent, followed by Keratinizing cystic odontogenic tumour [32%], Odontome [6.2%], Adenomatoid odontogenic tumour [5.5%], Odontogenic myxoma [2.4%], Ameloblastic fibroma [0.6%], Calcifying epithelial odontogenic tumour [1.8%] and Squamous odontogenic tumour [1.2%]. The total frequency of odontogenic tumours was 2.17%. Ameloblastoma and Keratinizing cystic odontogenic tumours were the predominant tumours, demonstrating significant regional and geographic variation.
