Background: Pathological processes of oral and maxillofacial region are generally classified as benign or malignant based on specific histological criteria, including the presence or absence of necrosis, mitotic figures as well as basic understanding of the entity.rnOdontogenic tumor (OT) comprises a large heterogeneous group of lesions arising from the tooth producing tissues or its remnants. It ranges from hamartomatous or non-neoplastic proliferations to benign and malignant neoplasm with variable aggressiveness and metastatic potential.rnOTs cause facial disfiguring that necessitates subsequent reconstructive surgery.rnThe objective of this study was to determine the types, prevalence and demographic distribution of benign Odontogenic tumor among patients treated at tikuranbessa specialized hospital and its affiliated hospitals.rnObjective: To assess the incidence and prevalence of benign Odontogenic tumor among patients treated at tikuranbessa specialized hospital and its affiliated Hospitals in Addis Ababa, Ethiopia over a retrospective period of 2 years from January 2020 to December2021.rnMethods: Retrospective review of patients records will be conducted among those patients who visited tikuranbessa specialized hospital and its affiliated hospitals diagnosed with benign Odontogenic tumorsâ€™ in the time period of January 2020 to December 2021 G.C. Data such as age, gender, duration of lesion, location of the tumors, size of the tumors, type of tumors, type of surgical treatment, and complaints during follow-up were reviewed. All the collected data were then coded, checked, edited and entered to SPSS windows 25. Finally, the data was analyzed by descriptive statistics.rnResults::A total of 68 patientâ€™s socio-demographic, and clinical data were reviewed from the registry book of patients who were diagnosed with OT. The complete data set was obtained for 55 patients, comprising 28(50.9 %) males and 27 (49.1 %) females. The mean age of patients was 30.4, with a range of (6â€“68) years. Concerning the location of OTs, 20 (36.4 %) occurred in the maxilla, and the vast majority 35(63.6%) in the mandible. Ameloblastoma with predilection for the mandible was the most frequent OT (32.7%), followed by keratocystic Odontogenic tumours (KCOT) (24.45 %).rnConclusions: OTs were found in both genders with similar proportion.rnCheckup and/or visit to dentists could help early case detection, and management of OT.
