Abstract
Objective: To report a clinical case where the evolution of caries caused pulp and structural impairment in a dental unit that, after endodontic treatment, was rehabilitated using a fiberglass pin and restoration with composite resin. Case details: Patient referred for oral rehabilitation by the endodontist after previous endodontic treatment of dental unit 25, which had extensive coronal destruction. Upon initial clinical examination, considerable involvement of the walls was observed: occlusal, mesial and vestibular. Taking into account the patient's complaint, clinical oral analysis and financial limitations, the following steps for treatment were proposed: installation of intraradicular pin and subsequent making of direct restoration in composite resin. The conduit was partially unclogged with subsequent preparation of the surfaces, cementation of the pin and restoration of the unit with composite resin, restoring aesthetics and function to the patient. Final considerations: The fiberglass pins have demonstrated excellent rehabilitation performance, it is up to the dentist to know and apply the correct installation of this intraradicular component.
