Abordagem endodôntica em dente com reabsorção radicular interna - relato de caso.

Abstract

Internal root resorption is characterized by the destruction of dentin from the wall of the root canal as a result of clastic cell activities as a result of physical or chemical trauma. Endodontic treatment is necessary to remove the etiology of resorption by using intracanal medication to combat possible infection, providing tissue repair. Generally, the prognosis of root resorption treatments is poor. This research aimed to report the treatment of an internal root resorption, evaluating its proservation. A 22- year-old male patient presented to the School of Dentistry of the Federal University of Campina Grande with painful symptomatology in the region of upper incisors and relative mobility in element 22. The radiographic examination revealed a radiolucent image, altering the contour of the root canal, suggesting an internal root resorption between the middle and apical thirds. Computed tomography of the conical bundle confirmed the diagnosis, accurately providing the extent of the lesion that communicates to the lateral periodontium. In the endodontic treatment, the Fava technique was used in the instrumentation and the calcium hydroxide paste was the intracanal medication of choice, remaining within the channels for an approximate period of 120 days, with periodic changes. In the obturation, the Tagger hybrid technique was performed with gutta percha cones and Sealer 26 endodontic cement. The postoperative control (3 and 6 months) revealed that the patient's reported symptoms had completely ceased. The repair of internal resorption was confirmed by periapical radiographs and computed tomography, requiring proservation for a longer period of time.
