Magnification in endodontics: the use of the operating microscope.

Abstract

(Figure 1) together with the power of ultrasonics and instruments for micro-endodontics are areas that have changed the face of endodontics. Until recently, endodontics was traditionally performed by hand with radiographic confirmation. To perform a root canal treatment often meant working inside a ‘black hole’ and many results were achieved by chance. Today, every challenge existing in the straight portion of the root canal system, even if located in the most apical part, can be easily seen and often solved under the microscope, with magnification and coaxial illumination. With the use of ultrasonics, the removal of posts, calcifications and broken instruments is faster, safer and easier. To locate missed canals or to negotiate calcified canals is more predictable using ultrasonic tips under the microscope. As far as new materials are concerned, recently Mineral Trioxide Aggregate (MTA) has become available. This is a revolutionary material, extremely biocompatible,
