Ledge Formation

[tirath]

Failure to grasp the rationale behind cleaning and shaping concepts can increase the occurrence of needless complications, such as ledges. A ledge is created when the working length can no longer be negotiated and the original pathway of the canal has been lost. Extension of the access cavity to provide unobstructed access to the root canals, precurving and not forcing instruments, using NiTi files, using passive step-back and balanced force techniques, and instrumenting the canal to its full length will all help to prevent ledge formation. Initial negotiation and bypassing the ledge can be achieved using a small file with a distinct curve at the tip, whereas a slight rotation motion of the file combined with a ″picking″ motion can often help advance the instrument.

RECAPITULATION is the only way one can avoid ledge formation
Till one doesnt realise the importance of cleaning and shaping the canals optimum preparation wont be reached and this leads to failure…….meticulous preparation of the canals is of utmost importance

Apical patency,apical gauging and recapitulation with constant irrigation and lubrication—golden rules for endo

Recapitulation also helps to clear off the clogged debris..this step is of utmost importance while using hand as well as rotary instruments..
