Résumé:
The dentigerous cyst is one of the most common odontogenic cysts
and it is associated with the unerupted crowns of teeth. Objective: To report a
clinical case of a dentigerous cyst in a pediatric treated through the marsupialization
techinique. Case report: A healthy, 10-year-old female patient was referred to the
Academic League of Surgery of the Federal University of Campina Grande (UFCG)
for treatment of a cystic lesion associated with the 35 tooth that was intraosseous.
Clinically, a vestibular bony bulge was observed in the region of the teeth 74 and 75
that presented cavities. The imaging test showed a radiolucent area surrounding the
tooth 35. The diagnostic hypothesis was a dentigerous cyst adn which was confirmed
by histopathological and the recommended treatment was the extraction of teeth 74
and 75 associated with marsupialization followed by enucleation of the cystic lesion,
under local anesthesia, aiming to support the eruption of teeth 34 and 35. Results:
The histopathological report confirmed the diagnosis of dentigerous cyst. In the
postoperative of 9-months after the marsupialization, new bone formation was seen
in the area previously occupied by the lesion, and teeth 34 and 35 are in occlusion
and with pulp vitality. No signs of recurrence of the lesion are observed. Conclusion:
Correct and early diagnosis of maxillary cysts helps to choose a conservative
treatment. The use of teeth associated with dentigerous cyst in pediatric patients
should be a determining factor in the choice of treatment.
