Management of a perforating internal root resorption using mineral trioxide aggregate: a case report with 5‐year follow‐up

Le résumé fourni par la source

Internal root resorption is characterised by progressive loss of tooth substance initiating at the root canal wall as a result of clastic activity. This report describes a case of a perforating internal root resorption on a maxillary central incisor in a 25-year-old patient. The perforating internal root resorption was firstly diagnosed with periapical radiographs and assessed with full detail with the aid of CBCT, allowing determination of the extension and areas involved in the resorption lesion, as well as the treatment planning. According to these findings, a MTA barrier was performed on the root, -coronally to the resorption lesion, leaving the root apically to the resorption lesion untouched. Clinical findings and periapical radiographs indicated complete resolution of the radiolucency associated with the resorptive defect, with reestablishment of lamina dura along the root and occlusion of the lumen of the root canal in the apical segment, after a 5-year follow-up.
