Maxillary Odontogenic Keratocyst Masquerading a Periapical Cyst

Odontogenic keratocysts previously termed, as keratocystic odontogenic tumor is a developmental odontogenic cyst. It is one of the most commonly occurring odontogenic cyst and is characterized by its aggressive behaviour, high recurrence rate and association with syndromes. A case of odontogenic keratocyst occurring in the maxillary anterior region is described here with emphasis on the importance of advanced imaging modalities like computed tomography in the diagnosis and treatment planning.
