Cisto dentígero bilateral em mandíbula em paciente não sindrômica: relato de caso

Abstract

Among the odontogenic developmental cysts, the dentigerous cyst is the most frequent, accounting for 20.6% of the cases. They usually occur in patients with an asymptomatic age range between 10 and 30 years old, of varying sizes, which can expand the cortical area and cause facial asymmetry. Depending on the size, it can be treated by marsupialization (Partsch technique), decompression (Thomas technique, marsupialization variant) and enucleation. This paper reports on the case of a 51-year-old female patient who complained of "I have a lesion in my mouth that is growing". At the clinical examination, bilateral facial asymmetry, normal lining mucosa, and absence of symptomatology were observed. Panoramic reconstruction of computed tomography showed circumscribed hypodense areas involving the crowns of the lower third molars. The aspiration puncture showed yellow-citrine fluid and the histopathological examination of the incisional biopsy was conclusive for a dentigerous cyst, bilaterally. The teeth involved (38 and 48) were removed and the decompression technique was applied for three months, followed by enucleation in a hospital environment, bilaterally. After three years of treatment, complete bone neoformation is observed.
