Background: Odontogenic lesions are tumours and cysts originating from the odontogenic epithelium and or ectomesenchyme and its vestigies. They are a wide array of cystic and neoplastic lesions which have been seen in all age groups. There is robust knowledge on the epidemiology of odontogenic tumours in all age groups, however paediatric odontogenic tumours due to their relative rarity have not been well researched and this has led to a conspicuous paucity of literature and knowledge gap on the specific demographics of these lesions in the paediatric age group. Objectives: To assess the prevalence, age, gender and site distribution of odontogenic tumours and cysts seen at the Lagos State University Teaching Hospital within the paediatric group between January 2013 and December 2017. Materials and methods: Records from the archives of the Department of Oral Pathology and Medicine, Faculty of Dentistry over a period of 5 years (January 2013 to December 2017) were reviewed. Information relating to the type of paediatric odontogenic lesion, age, gender and site of lesion was extracted and recorded on data forms. Lesions were grouped into primary dentition (0 to 5 years), mixed dentition (6 to 12 years) and permanent (13 to 17 years) dentition periods. Data was analyzed using SPSS (version 20). Result: Paediatric odontogenic lesions comprised 40 cases (29.63%) of the total odontogenic lesions, 30.53% of all paediatric lesions and 6.64% of all paediatric orofacial lesions seen within the 5 year study period (January 2013 to December 2018).
