Actitud terapéutica frente a una reabsorción interna perforante

Abstract

Based on the location of the root resorption, it can be classified as external or internal. Internal resorption is relatively rare, and its etiology and pathogenesis is not yet entirely clear. This article shows the complexity of a superior central incisor with a perforating inflammatory internal resorption. The definitive diagnosis is found through the three-dimensional examination, which confirmed the extension and communication with the external root surface. Although as we can see throughout the presentation of the clinical case, the help of the microscope allowed us to address the case with greater certainty. At all times we were able to remove the inflammatory tissue and prepare the duct properly. The obturation in this type of cases supposes a challenge for the endodontist, being this one, greater when it is done only in an ortograde way. For the filling, we performed a technique described in the literature, filling the apical area with resorption with gutta-percha adapted by vertical condensation; the resorptive zone with bioceramic material and finally the coronal zone with injected gutta-percha. A 3D was performed at 26 months for a new evaluation of the resorptive zone, and thus evaluate the bone state around it. The patient presents totally asymptomatic without clinical signs and with good health of the periapical tissues.
