Article history: Objectives: The aim of the present study was to carry out a retrospective analysis and eval-
Received 8 October 2019 uate the recurrence rate of cases histopathologically diagnosed as odontogenic keratocysts
Accepted 11 August 2020 in an Oral Pathology Service in Northeastern Brazil.
Available online 11 September 2020 Methods: The data of the present research were obtained from clinical files from our Service,
and included information on patients’ age and sex, keratocysts’ anatomical location, asso-
Keywords: ciation with teeth and radiographic aspect, type of biopsy, symptoms, type of data collected,
Odontogenic keratocyst treatment, recurrence, and possible association with Gorlin syndrome.
Recurrence Results: During the study period, 15,670 case records of maxillofacial lesions were obtained,
Surgical diagnostic techniques of which 106 (0.67%) were histopathologically diagnosed as odontogenic keratocysts. Recur-
rence was observed in 13.2% of cases.
Conclusions: The recurrence of odontogenic keratocysts was not associated with their ana-
tomical location, the patient’s sex, or the radiographic appearance at the time of diagnosis.
Odontogenic keratocysts were identified as a non-aggressive cystic lesion, with a low rate
of recurrence when treated conservatively by decompression and surgical enucleation. (Rev
