Keratocystic odontogenic tumours (KCOTs) are commonly seen in the posterior mandible. They can also rarely occur in the anterior mandible and mimic a lateral periodontal cyst (LPC). Intrabony pathology is rarely seen in the anterior mandible and unilocular appearance is even rarer. We present a case report of a KCOT of the anterior mandible which appeared in the plain radiographs as a unilocular radiolucency and clinically resembled a lateral periodontal cyst.
A 23-year-old male patient was referred to the Department of Oral and Maxillofacial Surgery by the GDP with a swelling in the lower right lateral incisor and lower right canine region with a duration of 3 weeks. The patient was asymptomatic. Clinical examination revealed a 1 cm diameter fluctuant swelling in the attached gingivae of the LR2 and LR3 extending into the labial/buccal sulcus and obliterating the sulcus. Mucosa overlying the swelling looked normal in colour. LR2 and LR3 were vital for ethyl chloride pulp testing.
