During root canal therapy, magnification and illumination provided by the operating microscope aids in numerous ways. The additional magnification and light help with
- Identifying complex canal anatomy.
- Seeing cracks and fractures not visible to the naked eye.
- Localization of obstructed and calcified canals.
- The removal of canal obstructions such as denticles and calcifications.
- Treatment of dental anomalies, such as dens invaginatus, or fused teeth.
- In endodontic retreatments, the microscope is helpful in identifying and removing leftover filling materials.
- Surgical endodontics has been completely transformed by microscopic procedures. Classic root surgeries are now microsurgeries, using smaller instruments to help reduce the amount of tooth structure removed.
