ODONTOGENIC KERATOCYST - A DECEPTIVE ENTITY

Odontogenic keratocyst (OKC) is the cyst arising from the cell rests of dental lamina. It can occur anywhere in the jaw, but commonly seen in the posterior part of the mandible. Radiographically, most OKCs are unilocular when presented at the periapexand can be mistaken for radicular or lateral periodontal cyst. When the cyst is multilocular and located at the molar ramus area, it may be confused to ameloblastoma. Lots of cases have been reported in the literature where OKC is associated with the non-vital tooth. So trauma could be one of the reasons in inducing this cyst.Presentcaseis of 30 years old femalewith a chief complaint of pain in lower back region and difficulty in mouth opening for 1 week reported in Department of Oral Medicine and Radiology in Divya Jyoti College of Dental Sciences and Research, Modinagar.
