Cisto dentígero em maxila de paciente pediátrica: relato de caso clínico.

Abstract

The dentigerous cyst is a bone-destructive lesion classified as a developmental odontogenic cyst of uncertain etiopathogenesis associated with a crown of permanent non-erupted dental elements. It is usually asymptomatic, being observed in routine radiographs, presenting as a radiolucent area with well defined limits involving the even tooth. Surgical treatment involves enucleation and / or marsupialisation, where the size of the lesion and its location guide the choice of therapy. It presents little chance of relapse and its prognosis is favorable. It occurs mainly in males between the second and third decades of life, but it has become an important injury in pediatric dentistry because it affects more and more children. This study aimed to report a clinical case of maxillary dentigerous cyst in an 11 - year - old patient, associated with element 15, asymptomatic, observed in routine panoramic radiography. The cavity had an estimated size of 17 x 16 x 09mm obtained from Cone Beam Computed Tomography. The enucleation technique was used to treat the cyst and exodontia of element 15. In the 30-day postoperative period, the patient did not report any complaints and the control X-ray revealed a new bone formation. Thus, enucleation proved to be efficient in this case, constituting a viable treatment option for cystic lesions in young patients.
