Influência do nível de experiência do operador na precisão do acesso endodôntico guiado em dentes com canais calcificados: uma revisão de escopo

Abstract

Introduction: Performing conventional endodontic access in teeth with root canal calcification is challenging due to the difficulty in locating and accessing the root canals. This approach can be time-consuming and may pose risks of excessive loss of dental structure, deviations, and even perforations. Guided endodontics emerges as an alternative technique that can facilitate access to the root canal system in teeth with calcifications. Objective: This scoping review aimed to assess the influence of the operator's level of experience on the accuracy of guided endodontic access in teeth with calcified canals. Methodology: The review involved searches in eight electronic databases until August 04, 2024, resulting in the initial identification of 999 records. After removing duplicates and selecting based on titles and abstracts, 31 articles were selected for full-text reading and analysis against the eligibility criteria. Included studies were published between 2019 and 2024 and addressed the influence of operator experience on guided endodontic access. Study evaluation included extracting the following data: study characteristics, objectives, employed methodologies, degree of tooth calcification, operator experience, planning and fabrication of access guides via 3D printing, and instruments used for access. Results: Analysis of the studies revealed significant heterogeneity regarding the models of guides used for guided endodontic access, operator experience, and evaluated parameters (deviation, canal location, wear, and time spent for guided access). However, despite this variability, none of the studies demonstrated a significant influence of operator experience on the accuracy of access guides in teeth with calcified canals. Conclusion: The guided endodontic technique can be a precise and predictable option regardless of the operator’s level of experience, provided it is properly planned and executed.
