Abstract Share this page

The odontogenic keratocyst, now known as the odontogenic keratocyst tumour (OKT), is a new entity included in the group of odontogenic tumors in 2005, due to its presenting intrinsic features compatible with neoplasms, such as a high recurrence rate and a differential growth mechanism. It is thought to arise from dental lamina remnants. It has a benign nature, a slow and asymptomatic development and a prevalence of approximately 35.8% among the odontogenic tumors. It affects males rather than females, showing a predilection for the posterior mandible and ascending ramus, being, in many cases, associated with an impacted tooth. Radio - graphically, OKT presents as unilocular, but when multilocular, it may be associated with the nevoid basal cell carcinoma syndrome (Gorlin’s syndrome). Histopathologically, it presents a parakeratinized stratified epithelial lining, with hyperchromatic basal cells. The outer layer is made up of fibrous connective tissue that may contain satellite cysts. The treatment ranges from conservative interventions to radical management, being directly related to the rate of recurrence. In view of the controversy concerning the classification of the odontogenic keratocyst as an odontogenic tumour, the present study reviews the current findings in the literature, focusing on its intrinsic features, with a view to contributing to the study of this new entity.
