IntroductIonCentral odontogenic fibroma (COF) is a rare, benign mesenchymal odontogenic tumor occurring within the jaw. 1 The World Health Organization (WHO) has defined it as a tumor consisting of mature fibrous connective tissue, with variable amounts of inactivelooking odontogenic epithelium, with or without the presence of calcification. 2 Histologically, there are two main subtypes of COF-the simple COF (epithelium-poor) type and the complex (epithelium-rich) type, also called the WHO type. [3][4][5] However, this classification was discontinued in the year 2017 because of its poor definition and documentation. The new classification of the lesion is now based on its location (central or peripheral) rather than on the basis of histological features. 6 In this case report, we describe a case of COF in a 13-year-old male, occurring in the left posterior mandibular region.
