Bypassing ledges and false canals. Instruments and techniques
Occasionally, during root canal instrumentation, instruments cannot be advanced to full working length in a previously patent canal. This may be due to ledge formation or false canal creation. Both these iatrogenic procedural accidents might affect treatment outcome if the canals below the blockages are infected. Bypassing the ledges and the false canals will re-establish the previously blocked canal pathway enabling full length disinfection procedures to take place. This lecture is designed to highlight the instruments, techniques and skills required for the successful management of ledges and false canals.
