[Odontogenic keratocyst in dentigerous position. A clinical case].

Cysts that may develop in the maxillo-mandibular region and adjacent tissues may be of odontogenic origin, non-odontogenic origin, pseudocysts, cysts associated with the maxillary sinus and those developed from the soft tissues. These may vary as to their histogenesis, frequency, behavior and treatment. This article presents the clinical case of an 18-year-old female patient with an initial radiographic diagnosis of dentigerous cyst, which after exploratory punction and surgical removal under general anesthesia yielded a final diagnosis of odontogenic keratocyst. The patient's evolution was satisfactory with a 2-year radiographic control, without evidence of recurrence.
