TEIXEIRA, Rubens Gonçalves et al. Decompression of a maxillary dentigerous cyst. RGO, Rev. gaúch. odontol. (Online) [online]. 2011, vol.59, n.2, pp. 299-303. ISSN 1981-8637.

This study describes the case of a dentigerous cyst in a six-year-old patient treated by decompression of the lesion. The patient's main clinical complaint was facial asymmetry with displacement of the nasal cavity. Clinical examination showed an extensive lesion in the left side of maxilla invading the nasal cavity. An interdisciplinary course of treatment for this patient was indicated to preserve the impacted permanent tooth inside the lesion. A panoramic radiograph and computed tomography scan were requested for planning the surgery. A decompression surgery was performed and an incisional biopsy revealed the presence of a dentigerous cyst in the maxilla. A second operation was performed two years later to disimpact the permanent incisor and promote its eruption by means of orthodontic traction. The patient was thoroughly followed for a few years. Bone repair at the dentigerous cyst site was perfect
