Odontogenic keratocyst with horizontal impaction of third molar

Abstract

Odontogenic keratocyst (OKC), previously known as keratocystic odontogenic tumor, are benign cystic lesions involving the mandible or maxilla and are believed to arise from dental lamina. What makes this cyst special is its aggressive behavior and high recurrence rate. This cyst is predominantly seen in younger patients (2nd–3rd decade) and may be seen in either the body or ramus of the mandible or maxilla. The distribution between sexes varies from equality to a male-to-female ratio of 1.6:1, except in children. There may be male predilection. Radiographically, it appears as unilocular or multilocular lesions with scalloped contour. This cyst is commonly detected incidentally. When symptomatic, jaw swelling and pain are common symptoms associated with this tumor. Less commonly, trismus and paresthesia may occur. Here, we present a case of OKC in a young male patient associated with an impacted right mandibular third molar.
