An<unk>  is classified by The World Health Organisation as a benign mixed odontogenic tumour (1). It develops from the dental tissues that grow into teeth. During human development, embryonic cells of ectoderm and mesenchyme produce epithelial and ectomesenchyme tissues. These proliferate and mature into ameloblasts and fibrous connective tissue (3), and ultimately teeth.<unk> s contain both of these tissues, and its name is derived from them. It is a neoplasm, meaning it is a mass of abnormal growth of cells or tissue. If the mass contains hard dental tissues they are known as odontoma, which are not true neoplasm, but classified as hamartomatous lesions (4) Epidemiology and prevalence Odontogenic tumours are uncommon, with a prevalence of around 2% (5) and only 1-2% of these are<unk> s (6). As they are rare, there is limited evidence available, mostly case studies. There is a slight male predilection, developing most commonly within the first two decades of life. They are often identified when tooth development is complete with the posterior mandible being the most common site. Although benign,<unk> s that occur in later decades as well as a third of treated<unk> s can recur and around 11% may undergo malignant transformation, though this figure is questioned (4, 7). Odontoma are the most prevalent of the odontogenic tumours in the early decades and<unk> s diagnosis should be considered.
