Odontogenic keratocyst: The role of the orthodontist in the diagnosis of initial lesions

•Several lesions of the jaws, including odontogenic keratocysts, can be identified in routine radiographic examinations.•Patients with radiolucent lesions of any size should have diagnostic investigation.•Orthodontists play an important role in identifying jaw lesions.

Odontogenic keratocysts (OKCs) are locally infiltrative odontogenic cysts that are usually diagnosed during routine radiographic examinations. Therefore, it is critical that dental practitioners, in particular orthodontists, recognize and diagnose OKCs to recommend appropriate treatment. This report describes a patient whose OKC was not initially identified during orthodontic pretreatment. In addition, this report discusses the clinical and radiographic features of OKCs, as well as the differential diagnoses of these lesions.
