Enucleação cirúrgica de cisto dentígero de grandes proporções associado a primeiro pré-molar inferior incluso: relato de caso

Abstract

INTRODUCTION: Odontogenic cysts are classified according to their origin in two groups: developmental cysts and inflammatory cysts. Among the developmental cysts, the dentigerous cyst stands out, as it is the second most common odontogenic cyst in the jaws. It is an intrinsic characteristic of this lesion to involve the entire crown of the affected non-erupted tooth and to be adhered to this tooth by the amelocemental junction. It has an idiopathic origin and is almost always asymptomatic, due to this factor, patients affected by this pathology are often diagnosed late. When diagnosis and treatment are performed at an early stage of the lesion, they can avoid changes such as: tooth movement, root resorption, expansion of cortical and bone fractures. CASE REPORT: The purpose of this study is to report the clinical case of a 34-yearold female patient, who had an enlarged volume in the left mandible region, asymptomatic and with an evolution time of approximately 12 months. The information was obtained through reviewing the medical record, interviewing the patient, photographic records and imaging tests whose the patient was submitted. Surgical enucleation was the method chosen to remove the cyst and the included lower left first premolar associated with the lesion. The specimen of the lesion was referred for anatomopathological evaluation and obtained the definitive diagnosis of dentigerous cyst. Considerable regression of the lesion is observed after surgical enucleation and it is possible to monitor the osseointegration through radiographic exams. FINAL CONSIDERATIONS: The treatment proved to be resolutive, however, it is important to emphasize that the choice of treatment should be judicious and carefully weighed for different types of cases.
