INTRODUCTION: The dentigerous cyst is the second most common odontogenic cyst in the jaws. It is a benign lesion of odontogenic epithelium derived from the crown of a tooth that has not erupted, but of uncertain etiology. They are generally radiolucent and usually unilocular. These lesions are observed in routine examinations or when the eruption of a permanent tooth is delayed. The third molars and maxillary canines are the most affected teeth, and also the high occurrence of this lesion is associated with supernumerary teeth and odontomas. The dentigerous cyst occurs mainly in the first three decades of life, It's growth is slow, asymptomatic and can reach considerable size causing facial deformity, displacement and impaction of teeth and/or surrounding structures. OBJECTIVE: Definition of marsupialization and enucleation techniques as well as consideration of important objective criteria for the treatment plan like cyst size, age, proximity to anatomical structures and clinical importance of the involved tooth. Despite the clinical peculiarities of each case and the chosen treatment method, the prognosis of these lesions are favorable when appropriate therapy is used. MATERIAL AND METHOD: This study will present a case report treated by maneuver of decompression followed by enucleation and discussion of treatment modalities. RESULT: The patient is on two years of postoperative without signs of relapse and absence of paresthesias in the face. CONCLUSION: The technique preserved the neurosensory function and was effective for the extinction of the lesion.
