Reabsorção externa inflamatória após luxação intrusiva dentária – conduta clínica de tratamento tardio

Abstract

External inflammatory root resorption (EIRR) is one of the consequences of pulp necroses caused by intrusive dislocation (ID). The objective of the study was to report a clinical case of ID associated with EIRR, which was submitted to late endodontic treatment. Patient came to the dental office five months after a trauma with a clinical picture of intrusive dislocation of tooth 21 associated with pulp necrosis, but without symptoms. Radiographic examination showed an image compatible with EIRR along root surface. The treatment plan was to undergo endodontic treatment with calcium hydroxide changes which occurred monthly for 8 months. When EIRR stopped, the root canal was filled. After clinical and radiographic follow up for 5 years, there was an involution of the damage caused by the clastic activity resulting from the resorptive process, characterizing the success of the instituted therapy.
