Use of Endoguide in Accessing a Calcified Maxillary Canine Using CBCT Guided: A Case Report

Abstract

Aims: To describe the endodontic treatment of a tooth with extensive calcification in the pulp chamber, using the guided endodontic technique (Endoguide). Case Report: A 36-year-old female patient, with normal systemic function, presented to the Dental Clinic of UFC - Sobral Campus for evaluation. After anamnesis, clinical and radiographic examinations, endodontic treatment was deemed necessary for tooth 13, which presented with necrosis and periapical rarefaction. The same radiographic examination identified that the tooth presented with pulpal calcification extending to the middle third of the root. As a complementary examination, a cone-beam computed tomography scan was requested, which guided the fabrication of the guide. With this guide and the aid of a specific drill operated at low speed, access to the root canal was achieved without major difficulties. Odontometry and instrumentation of the canal were then performed with instruments from the Reciproc system (R25 and R40); subsequently, calcium hydroxide paste was applied and remained in place for 21 days. The root canal obturation was performed with Hydro Sealer endodontic cement and gutta-percha using the modified Tagger Hybrid technique. Conclusion: 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 risk of accidents and increasing the predictability of the procedure.
