The root canal filling material (3, 4, and 10) does not extend to the end of the tooth roots (5, 6 and 11). The dark circles at the bottom of the tooth roots (7 and 8) indicated infection in the surrounding bone. Recommended treatment is either to redo the root canal therapy or extract the tooth and place dental implants.
Periradicular surgery should be very considered where previous endodontic treatment has failed, and possible re-root treatment is the preferred option. [4] If re-root treatment is not possible, will not correct the problem or patient factors prevent it, periradicular surgery is indicated.
An unusual root canal shape, complex branching (especially the existence of horizontal branches), and multiple root canals are considered as the main causes of root canal treatment failures. (e.g. If a secondary root canal goes unnoticed by the dentist and is not cleaned and sealed, it will remain infected, causing the root canal therapy to fail).
The cost of a root canal depends on the complexity of the dental issue and the tooth that needs treatment. According to the American Association of Endodontists, molars are more complex to treat ...
A root end surgery, also known as apicoectomy (apico-+ -ectomy), apicectomy (apic-+ -ectomy), retrograde root canal treatment (c.f. orthograde root canal treatment) or root-end filling, is an endodontic surgical procedure whereby a tooth's root tip is removed and a root end cavity is prepared and filled with a biocompatible material.

These teeth often have thin root canal walls which are susceptible to fracture after treatment. Therefore, complete cleaning and shaping as well as obturation of these teeth are difficult or sometimes impossible, due to high risk of fracture during the procedure [ 48 ] Clinical outcome of regenerative endodontics can be observed within 6 months ...
Mineral trioxide aggregate (MTA) is a recent development of the 1990s [21] initially as a root canal sealer but has seen increased interest in its use as a direct pulp-capping material. [10] The material comprises a blend of tricalcium silicate , dicalcium silicate and tricalcium aluminate ; bismuth oxide is added to give the cement radiopaque ...
