The success of endodontic therapy relies on the localization of the entire root canal system and its subsequent cleaning, shaping and three-dimensional obturation.
The increased magnification and illumination provided by the microscope allows enhanced visualization of the working area. This, in turn, allows for more efficient technique and greater ability to achieve success in surgical and non-surgical endodontics.
Advantages of the use of a microscope:
- Procedural errors can be greatly reduced, if not eliminated, and complicated cases become less so under the microscope.
- The microscope is an excellent tool to help the clinician to detect micro fractures that cannot be seen by the naked eye.
- Locating missing canals as the root canal anatomy is extremely complex.
- Management of calcified canals which are easier to detect under high magnification as the colour and texture between the calcified canal and the remaining dentine can be easily seen.
- Perforation repair: Perforation does occasionally occur no matter how carefully the tooth is accessed for endodontic therapy. When a perforation occurs, the microscope is the key instrument to identify and evaluate the damaged site. The result of a careful inspection will be the basis for which the possible perforation repair can be made.
- Retrieval of broken instruments: endodontic instruments can separate inside the canal. Dependant on the location of the severed instrument, then the use of the microscope will be essential to enable the clinician to retrieve it with minimum damage to the surrounding dentine.
- Endodontic microsurgery (apicectomy) can be performed under high magnification and illumination and with the use of microinstruments which will result in the procedure being executed with much more precision and predictability.
