Radiopacity within a Radiolucency: An Interesting Case Report

Odontomas are benign, asymptomatic, slow-growing tumours of odontogenic origin comprising different dental tissues. They are considered to be hamartomas rather than true neoplasms. They develop from epithelial and mesenchymal components of the dental apparatus, producing enamel and dentin. Appearance is usually comparable to that of a normal tooth in size and shape. Occasionally, a complex variety exhibits considerable growth. Usually asymptomatic, odontomas are often discovered during routine radiological examination or when they deform the adjacent teeth. Odontomas can be classified morphologically as complex (presents as irregular masses containing different types of dental tissues) or compound (superficial anatomic similarity to even rudimentary teeth known as denticles), . Dentigerous cysts are odontogenic cysts that arise through the accumulation of fluid between reduced enamel epithelium and the tooth crown. Typically, they affect impacted teeth, in the majority of cases mandibular third molars and maxillary canines. It is commonly found in patients who are 30 years of age or younger. In this poster, we present a case report of a dentigerous cyst associated with complex odontomas in a 12-year-old female. Keywords: odontoma, dentigerous cyst, impacted teeth, dilated odontome
