Emprego do endoguide no acesso de um canino superior calcificado: relato de caso

Abstract

Guided Endodontics is a recent approach that uses a 3D-printed guide to direct the removal of hard tissue during access cavity preparation in teeth with calcified pulp chambers. In this context, the present report aims to describe the endodontic treatment of a tooth with extensive pulp chamber calcification. The patient, a 36-year-old female, in general good health, visited the Dental Clinic at UFC - Sobral Campus for evaluation. After medical history review, clinical, and radiographic exams, it was determined that endodontic treatment was necessary for tooth 13, which was necrotic with periapical rarefaction. The radiographic exam also revealed Pulp calcification extending into the middle third of the root. A cone-beam computed tomography (CBCT) scan was requested as a complementary exam, which guided the fabrication of the guide. Using this guide and a low-speed specific drill, the root canal was accessed without significant difficulties. Root canal measurement and instrumentation were performed with Reciproc system instruments (R25 and R40); thereafter, calcium hydroxide paste was Applied and left for 21 days. The root canal obturation was performed with Hydro Sealer endodontic cement and gutta-percha using the modified Tagger’s hybrid technique. Based on the description, it can be concluded that the Endoguide proved to be an efficient and easy-to-use tool, acting as a facilitator during the endodontic treatment of the reported case, minimizing the risks of accidents and increasing the predictability of the procedure.
