Abstract

|
Calcifying epithelial odontogenic tumor (CEOT) is a rarely reported benign tumor, accounting for 0.4-3% of all odontogenic tumors. Approximately 150 cases have been reported in the literature between 1958 and 2003. The age range of CEOT varies from 8 to 92 years with mean of 36.9 years, and the occurrence of the lesion in both genders is almost equal. It has 2 clinico-topographic variants: the intraosseous (94%) and the extraosseous (6%) type. The intraosseous type has a predilection for mandible (maxilla : mandible ratio of 1 : 2). The intraosseous CEOT commonly associated with non-erupted teeth accounts for more than half (52%) of the cases and usually appears as painless swelling that causes bony expansion. The location of diffused round-shaped calcifying material is inside the connective tissue stroma and epithelial islands. The tumors tend to be located toward the tooth crown, which usually has a unilocular radiolucent region containing variant radiopaque materials radiologically. In this paper, we report a case of CEOT occurring in the left mandibular first premolar of a 23-year-old female and present a brief review of the literature.
