What is ledge formation in root canal?

What is ledge formation in root canal?

Ledge formation, that is the iatrogenically created irregularity in the root canal that impedes access of instruments to the apex, and canal blockage caused by packing dentin chips and/or tissue debris are the least-studied parameters of root canal instrumentation.

Which handpiece is used for root canal treatment?

The AW-100 is an air-driven handpiece specifically designed for root canal preparation and irrigation.

What happens if a file breaks in a root canal?

Instrument breakage during treatment can lead to serious complications and carries the risk of treatment failure. When a file breaks in the canal, bypassing or removal can be difficult and the long-term prognosis of the tooth may be compromised. Sometimes surgery may be indicated for removal of the broken segment.

How do you dry out a root canal?

To dry root canals the cotton-wrapped instrument can be inserted into the canal and then rotated clockwise with slight pressure to reach the working length. If the instrument will not reach the working length it can be rewound with less cotton, or another instrument one size smaller can be used.

How do you negotiate a calcified root canal?

Usually, if you use small hand files such as a size 6, 8 or 10 K-file you will then be able to negotiate further into a system once some coronal pre-flaring has taken place. Alternating between rotary and hand instrumentation while constantly bathing the pulp chamber of the tooth can expedite negotiation to the apex.

How do you treat a blocked root canal?

A blocked canal may be due to calcium deposits generated by the tooth. In this situation, every effort is made to work through the calcified area and seal the canal. If the effort is unsuccessful, endodontic surgery may be necessary to seal the canal at the end of the root within the jawbone.

What happens if root canal filling comes?

Fillings, whether temporary or permanent, are weaker than crowns. They are more susceptible to cracking, breaking, or becoming loose and falling out of the tooth. Once a filling breaks or falls out, you have a higher risk of developing a second infection, followed by tooth decay.
