Odontogenic Keratocyst of Maxillary Premolar Region: A Case Report.

ABSTRACT

Odontogenic keratocysts (OKC) are enamel organ or dental lamina derived cysts and are not thought to be associated with any infection. They mainly occur in second and third decades of life. The purpose of this case report is to describe a rare case of OKC in a 10-year-old girl, associated with upper left unerupted maxillary first premolar. It involved maxillary sinus leading to erosion of left orbital floor. It also led to the displacement of adjacent maxillary canine and maxillary left second premolar above the unerupted maxillary left third molar. Due to the aggressive nature of the cyst, it was enucleated and followed-up.
