Background: The frequency and incidence of odontogenic cysts and tumors are controversial and depends in the geographic location. These lesions have great clinical and histopathological diversity, and reflect a need for epidemiological profile to be considered when these lesions are studied.

Aim: The purpose of this study was to determine the prevalence of odontogenic cysts and tumors over a period of 10 years and to compare with other data reported around the world.

Materials and Methods: Data for the study were obtained from the archives of the Department of Oral and Maxillofacial Pathology, diagnosed as the cases of Odontogenic cysts and tumors histopathologically, reported from January 2007 to March 2016. Case records of the patients that fit the histological classification of the World Health Organization (2005) were included in the study and the variables analyzed were: Age, sex, anatomical location, and histological type.

Results: In a total of 1319 biopsies reported, 112 were odontogenic in nature. Of these 112 odontogenic lesions reported, Odontogenic Cysts accounted for 54.4% and odontogenic tumors of 45.53%. Of them 61.60% of the patients were males. Common age of occurrence was 21-50 years and mandibular posterior was the most common site of occurrence. Most common odontogenic cyst and tumor reported was dentigerous cyst and ameloblastoma respectively.

Conclusion: This study provides epidemiological information on odontogenic cyst and tumors at an institutional level. The relative frequency of these cysts and tumors can be analyzed at a global level to understand their prevalence, incidence, biological behaviour, and distribution.

Keywords: Ameloblastoma; Cysts; Incidence, Prevalence; Odontogenic; Tumors.
