ENUCLEATION OF AN EXTENSIVE DENTIGEROUS CYST IN THE MAXILLA – CASE REPORT

Abstract

This article aims to report a clinical case of a 12-year-old male patient who presented with swelling in the anterior region of the left maxilla, associated with impacted tooth 23, with characteristics suggestive of a dentigerous cyst. Methodology: A retrospective, descriptive observational study based on the analysis of medical records, imaging examinations, and photographic records, with authorization through the informed consent form (ICF). Results: The patient presented for care at the Center for Research on Craniofacial Anomalies (CEAPAC/HUOP/Unioeste), with the Oral and Maxillofacial Surgery and Traumatology team of the University Hospital (HUOP), in Cascavel, Paraná, Brazil, due to swelling in the anterior region of the left maxilla, between teeth 63 and 25, observed during a routine dental consultation. Surgical treatment consisted of enucleation of the lesion and removal of the impacted tooth, with histopathological confirmation of the diagnosis. Conclusion: Dentigerous cysts are developmental odontogenic lesions associated with the crown of impacted teeth, mainly canines and third molars. Although benign and asymptomatic, they may cause facial asymmetry, tooth displacement, and root resorption. Computed tomography is essential for assessing the extent of the lesion and its relationship with anatomical structures, guiding the therapeutic choice among enucleation, marsupialization, or decompression. Early diagnosis and appropriate treatment prevent complications and recurrence.
