Endodontic approach in tooth with internal root resorption: case report

Abordagem endodôntica em dente com reabsorção radicular interna: relato de caso

ABSTRACT

Internal root resorption is characterized by the destruction of dentin from the root canal wall because of clastic cell activity; endodontic treatment is necessary to remove its etiology. Intracanal medication and an adequate filling are essential for treatment and are essential to prevent recurrence. This research aimed to report on the treatment of an internal root resorption, evaluating its follow up. 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, changing 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, Fava’s technique was used in 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’s hybrid technique was performed with gutta percha cones and Sealer 26 endodontic cement. According to the case described, it was possible to observe that the postoperative control (3 and 6 months) revealed that a symptomatology related by the patient had completely processed. Repair of internal resorption was confirmed by periapical radiographs and computed tomography, requiring follow-up for a longer period. The thermoplastic endodontic obturation using Tagger’s hybrid technique and the use of Ca(OH)₂ inside the root canal system, for a long period of time, through the treatment of internal root resorption, shows impressive results for this pathology.
