SANTOS, Marconi Eduardo Sousa Maciel et al. Dentigerous cyst in a child: a peculiar case treated by decompression. Rev. cir. traumatol. buco-maxilo-fac. [online]. 2011, vol.11, n.3, pp. 21-28. ISSN 1808-5210.

The dentigerous cyst is the second most frequent odontogenic cyst, the development of which starts from an alteration in the reduced epithelium of the enamel organ, where a liquid accumulation occurs between the epithelium and the organ. Normally it is related to the crown of an unerupted tooth, adhering to it at the cementoenamel junction. It is generally asymptomatic and is usually discovered in routine radiographic examinations or in the absence of eruption. Its radiographic aspect is a well-circumscribed radiolucent area, but it may assume large proportions, causing facial asymmetry and pain. There are several forms of treatment, and its prognosis is quite favorable. The aim of the present article is to report a clinical case in which the decompression technique was used in the treatment of a major cyst in a 10-year-old child, who initially presented a large facial asymmetry on the left side of her face and a cystic lesion extending from the left side of the jaw to the orbital floor, with displacement of a number of permanent teeth.. The case was followed clinically and radiographically for 9 months and at the end of the cystic decompression there was a considerable decrease in the size of the lesion and a reorientation of the eruption axis of the permanent teeth with no need for their removal
