Sürmüş Odontoma: Üç Vaka Raporu Ve Li̇teratür Derlemesi̇

Abstract

The term 'odontoma' was first used in 1866 by Broca who defined it as a tumor formed by the overgrowth of complete dental tissue and in 1946 it was classified by Thoma and Goldman. 1 Odontomas, which are considered developmental anomalies (hamartomas) rather than true neoplasms are the most common benign odontogenic tumors and composed of enamel, dentin, cementum, and pulp. Various theories have been suggested for etiology of odontomas: local trauma in primary dentition duration, infectious and/or inflammatory processes, hereditary abnormalities, and any alteration in genetic structures that can affect the tooth development. 2 Odontomas are the most frequently observed, non-cystic, non-aggressive, usually asymptomatic, odontogenic benign lesions, and among the odontogenic tumors their incidence ranges between 22-67%. 3 According to the World Health Organization (WHO) classification in 2017, based upon its radiographic, histopathologic, and clinical features, there are two types of odontoma: complex odontoma (CxOD) and compound odontoma (CpOD). 4 CpOD present organized dental tissues and might contain tooth-like structures that are named denticles. On the contrary, CxOD is consists of all dental tissues that arrange randomly. 5 Their detection is usually in the early years of life, between the ages of 6 and 46, and the mean is 23 years old.4 The sex predilection is controversial; in some studies CpOD reported more common in males, and CxOD slightly more common in females.5 Dilated odontoma represented as a dilatation of the crown and root that cause of a deep enamel-lined invagination and it is a very rare developmental abnormality.6 Although it has been described as another type of odontoma by some authors, it was not described as a private asset in the
