RIVERO PEREZ, Oscar; ALBORNOZ LOPEZ DEL CASTILLO, Carlos  e  NAPOLES GONZALEZ, Isidro de Jesús. Residual cyst: a case presentation. AMC [online]. 2014, vol.18, n.5, pp. 578-586. ISSN 1025-0255.

Background: a cyst is a structure with a tendency to be rounded, made up of an external wall of fibrous connective tissue, an internal wall composed of epithelial tissue. The cystose cavity contains sallow liquid or semiliquid material that, when becomes infected, gets purulent and brown. A residual cyst could have been previously a lateral cyst or an apical cyst and when the tooth is extracted from the periodontium, the cyst remains in the osseous tissue without being removed. Objective: to present a case diagnosed and treated for a mandibular residual cyst that extended over the left hemiarcade. It was possible to re-establish the masticatory and aesthetic functions. Clinical case: a patient who was treated in the Maxillofacial Surgery consultation of the Faculty of Stomatology of Camagüey. The patient presented a volume increase in the left lateral region and an antecedent of front trauma that caused fracture of the lower jaw. The clinical characteristics of the disease and the surgical treatment conducted are described. The principles of the enucleation technique were used for conducting the surgical treatment. Conclusions: in spite of the fact that few cases have been reported in the national and foreign literature, these have been smaller cysts that included one or two teeth. There are no reports of residual cysts that extend over all the dental arcade or hemiarcade. Satisfactory aesthetic results were obtained with the surgical technique applied and there were no complications.
