The odontogenic keratocyst (OK) classified by the World Health Organization (WHO) as a benign developmental cyst, stands out among other odontogenic lesions because of its potentially aggressive biological behavior, prone to recurrence. This work aims to report a case of OK in the mandible, as well as discuss aspects related to the radiographic findings and ways of treatment. Male patient, white skinned, had shown a circumscribed, radiolucid lesion with a hardened consistency, six months old, measuring approximately 1 centimeter wide on the posterior left mandible region. Under the clinical hypothesis of odontogenic developmental cyst, an incisional biopsy was successfully made. Based on the definitive diagnosis of OK after the histopathological exam, the removal of the affected teeth was then realized, as well as the implementation of an intraosseous device so the decompression of the OK could happen. After six months a partial regression of the lesion was observed, the intraosseous device was then removed and the remaining lesion was removed through a peripherical osteotomy. After a year of proservation, no recurrence of the OK was observed to this moment. The present case findings stress the importance of a clinical and radiographic diagnosis, as well as the right surgical treatment, praising the importance of a thorough clinical exam of the oral cavity.
