Resumen:
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.
