The aim of this case report is to describe the purpose and performance range of magnification devices (loupes, microscopes) in endodontics, and their advantages and disadvantages in everyday work. Magnification devices will be an unavoidable aspect of the endodontic treatment in the near future, which is indeed justified given the fact that the usage of such aids leads the result of endodontic treatment to perfection. Unlike traditional endodontics, modern endodontics, with the help of magnification devices, allows the therapist to work at high magnifications, optimal working ergonomics and lighting, and the morphology of the endodontic system is being fully respected and a minimally invasive approach to treatment is possible. Depending on the need for magnification, lighting, precision and treatment goals, the therapist may use a magnifying loupe as a simpler optical system or operating microscope (OPMI) as the largest attainment of all magnification devices. In addition to the undeniable advantages of working with magnification devices, the disadvatages are relative in nature, and relate to the cost of devices, longer working hours, especially for beginners, and the need for dental assistance.
