A review of odontogenic keratocyst with a report of unusual occurrence in the maxilla.

Odontogenic keratocysts (OKC) are keratinizing epithelium-lined cycts of the jaws with well-defined histologic criteria and possessing one clinical feature warranting their recognition and separation as a distinctive entity, due to their exceedingly high recurrence rate. This report describes a case of OKC which occurred in the anterior maxilla in a 12 year old female child, with its treatment. These lesions are normally seen in the mandible, and are rare in the maxilla.
