Introduction:

A drawback of permanent tooth eruption is tooth retention. A retained tooth has not completed its eruption and has not reached its normal position in the jaw. Retained teeth may be within the jaw asymptomatic or causing tooth migration, persistence of deciduous teeth, alterations in occlusion and aesthetics, formation of tooth cyst and tumors.

Objective:

Describe the enucleation of dentiger cyst, associated with the lateral incisor, and orthodontic traction of retained upper canine.

Case presentation:

Female patient, 19 years old, with persistence of teeth 52 and 53. Tomographically there is a right upper lateral incisor retained in a horizontal position, associated with a radiolucent image of dimensions of 11.2 mm x 20.1 mm and a canine retained in an upright position. Exodontics were performed at the flap of the lateral incisor and enucleation of the cyst. Regarding the canine, the orthodontic button was placed for subsequent traction. The definitive histopathological diagnosis was tooth cyst.

Conclusions:

Lesions associated with retained teeth may have several differential diagnoses. The specialist must know the clinical and radiographic characteristics of each of them and project the treatment plan according to the criteria of location, size of the lesion, age, systemic status, among others. Knowledge of surgical technique and histopathological diagnosis avoids complications.
