Endodontic treatment is the removal of pulp tissue from teeth and the filling and sealing of the canal system. The microscope allows a maximization in the visualization of the canals which facilitates a thorough examination of the piece in question and consequently achieve a much more accurate and effective treatment. Objective: To learn about the application of the microscope in endodontics in relation to the manual technique and the use of magnifying loupes. Materials and methods: An analytical and descriptive approach was used, where the collection of bibliographic information was obtained through an analysis, classification and search of articles with scientific evidence based on data from 2017 to 2022, in search engines such as: PubMed, Scielo, Latindex, Dialnet, Google academic, among others. Results: It is evident that the number of advantages of microscope use is much greater in relation to its disadvantages. Microscopes outperform magnifying loupes in most variables except cost. A series of dental treatments are detailed with the use of the microscope that allow greater precision in dental diagnosis when visualizing details in composition with the operator performing manual techniques. Conclusion: The microscope and magnifying loupe have allowed greater precision in endodontic treatment because they facilitate the work and visibility in the small canals of the dental pieces.
