Emprego de guia endodôntico em dente com canal calcificado e submetido a complementação com cirurgia paraendodôntica: relato de caso clínico e revisão de literatura.

Abstract

INTRODUCTION: Root canal obliteration can be triggered by several factors such as dental trauma, extensive carious lesions, occlusal imbalance or aging, depending on the degree of root development, it can be classified as partial or total. In recent years, there have been significant advances in Dentistry, including the implementation of high-resolution cone beam computed tomography in clinical practice, aiming to improve the accuracy of diagnosis in its three-dimensional dimension. The combination of these technologies allows the use of endodontic guide. It is a viable, safe, 3D method to locate calcified canals and prevent root perforation in teeth that cannot be accessed through conventional endodontic therapy. OBJECTIVES: To describe the clinical case of a patient with an obliterated canal undergoing endodontic treatment using an endodontic guide and undergoing paraendodontic surgery. METHODOLOGY: The patient who participated in this case was treated at the Clínica Escola do Centro Universitário Goyazes, diagnosed with an obliterated canal with difficult access in the conventional manner, for endodontic treatment with an endodontic guide with surgical complementation.And the integrative literature review carried out by searching for scientific articles in the PubMed database addressing guided endodontics and paraendodontic surgery. FINAL CONSIDERATIONS: Guided endodontics was essential to accurately locate the obliterated canal, preserving the tooth structure and avoiding complications. In view of the recurrence of the periapical lesion, paraendodontic surgery with guided apicoectomy proved to be an effective and predictable approach, allowing safe and controlled surgical access.
