Abstract
Cementoblastoma is characterized by the formation of cementum-like tissue attached to the root of a tooth. It is a benign neoplasm with odontogenic mesenchymal origin, and is considered the only true neoplasm of cemental origin. Cementoblastomas are usually located in the mandible, the majority of which affect the permanent first molar. There is no distinct gender preference and the mean age of occurrence is approximately 20 years of age. The lesion is usually identified as well defined, radiopaque, delimited by a cortical border, and with a well-defined radiolucent band just inside this cortical border. Root resorption and loss of the root outline are commonly associated with the cementoblastoma. The only treatment is enucleation of the lesion with removal of the associated tooth. Here, we present an unusual cementoblastoma case in a 52-year-old woman with different radiographic findings from those frequently reported in the literature. The patient has been followed for 2 years with no sign of recurrence.
