On the other hand, the root canal filling material may be extruded from the apex leading to other complications. [citation needed] The X-ray in the right margin shows two adjacent teeth that had received bad root canal therapy. The root canal filling material (3, 4, and 10) does not extend to the end of the tooth roots (5, 6 and 11).
Composites and amalgam are used mainly for direct restoration. Composites can be made of color matching the tooth, and the surface can be polished after the filling procedure has been completed. Amalgam fillings expand with age, possibly cracking the tooth and requiring repair and filling replacement, but chance of leakage of filling is less.
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.
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).
In root canal therapy, the pulp of the tooth, including the nerve and vascular tissues, is removed along with decayed portions of the tooth. The canals are instrumented with endodontic files to clean and shape them, and they are then usually filled with a rubber-like material called gutta percha. [144] The tooth is filled and a crown can be placed.
In fact, water flossers "do not remove plaque as successfully as traditional floss and should be used in conjunction with floss," says Khan. "Flossing breaks down the bacteria colonies from teeth ...
If apical closure has not occurred within six months, the root canal is retreated again with the material of choice. Ideally, the tooth should demonstrate continued apical growth and closure or an apical stop. When closure is observed, the canal is filled with a root canal filling material known as gutta-percha.

Hummus paired with fresh vegetables or pita invites curiosity about its nutritional virtues. With its origins tracing back to the Middle East, the chickpea-based spread has captured the hearts and ...
