Endodontia guiada: um avanço no acesso endodôntico de canais calcificados

Abstract

This report describe a case of guided endodontic access (GEA) used to localize and treat the teeth with partial pulp canal obliteration. Case report: Cone beam computed tomography and an intra-oral scanner images were matched by means of virtual planning software. After planning the position of the drill and sleeve, a virtual template was designed and sent to a 3D printer for fabrication of the respective guide. The guide was positioned and the root canal was localized with a carbide bur (diameter 0.8 mm). The root canal was prepared with reciprocating files under irrigation with sodium hypochlorite. The tooth was filled with the thermoplasticized gutta percha single-cone technique. The patient was followed-up for 6 months and demonstrated absence of signs and symptoms. Conclusion: Endodontic treatment associated with GEA was an effective therapeutic option in case of pulp canal obliteration of maxillary central incisor, to obtain safe and reliable endodontic treatment results.
