RETROSPECTIVE ANALYSES OF 300 CASES OF ODONTOGENIC KERATOCYST

Objectives To analyze the clinical and radiographic features of odontogenic keratocyst (OKC) from a Brazilian oral and maxillofacial pathology reference center. Study Design Data regarding sex, ethnicity, age, time of evolution, symptoms, location, radiographic features, size, treatment, and recurrence of OKC were collected. Results Among 37,029 oral biopsies, 1915 (5.2%) were odontogenic cyst, of which 300 (0.8%) met the criteria of OKC. Males (51.3%) of African descent (57.1%) were more prevalent. Individuals in their third decade (31.4%) were more affected. Asymptomatic lesions (79.3%) were reported by most of the patients. Radiolucent (100.0%), well-defined (27.9%), unilocular (28.4%) lesions with a mean size of 3.5 cm on the posterior mandible (48.9%) were more commonly found. Impacted teeth were associated in 30 cases. The percentage of cases surgically excised was 65.8%. Recurrence was seen in 67 patients (25.4%). Conclusions The findings of this study were similar in many ways to previous reports. However, concerning skin color, the literature shows a greater number of cases in Caucasian individuals.
