The Operating Microscope is an important addition to the armamentarium of modern endodontics. It helps set the bar of excellence at the highest level. Operating microscopes are useful right from diagnosis, trying to locate extra canals or missed canals, assessing efficacy of newer systems for cleaning and shaping, to prevent / or manage endodontic complications.
The introduction of the operating microscope has changed both non-surgical and surgical endodontics. In non-surgical endodontics, every challenge existing in the straight portion of the root canal system, even if located in the end of the root, can be easily seen and managed competently under the microscope. In surgical endodontics, it is possible to carefully examine the root-end and perform a resection of the root.
Use of Microscopes in Endodontics:
The following procedures benefit from the use of the microscope:
locating hidden canals that have been obstructed by calcifications and reduced in size;
removing materials such as solid obturation materials (silver points and carrier-based materials), posts or separated instruments;
removing canal obstructions;
assisting in access preparation to avoid unnecessary destruction of mineralized tissue,
repairing biological and iatrogenic perforations;
locating cracks and fractures that are neither visible to the naked eye nor palpable with an endodontic explorer;
facilitating all aspects of endodontic surgery, particularly in root-end resection and placement of retrofilling material.
