Root canal treatment (also known as endodontic therapy, endodontic treatment, or root canal therapy) is a treatment sequence for the infected pulp of a tooth that is intended to result in the elimination of infection and the protection of the decontaminated tooth from future microbial invasion.
[6] [7] As a result, necrotic tissue located within the pulp chamber and canals provide nutrients for pathogenic bacteria to grow and form a periapical lesion; [8] the infected tooth serves as a biochemically and physiologically ideal location for bacterial growth and maturation, and, in essence, acts as a refuge from which bacterial ...
Root canal anatomy consists of the pulp chamber and root canals. Both contain the dental pulp. The smaller branches, referred to as accessory canals, are most frequently found near the root end (apex), but may be encountered anywhere along the root length. The total number of root canals per tooth depends on the number of the tooth roots ...
The part of the pulp inside the crown is the pulp chamber, and the central soft tissue nutrient canals within each root are root canals, exiting through one or more holes at the root end (apical foramen/foramina).
Conventional root canal therapy cleans and fills the pulp chamber with biologically inert material after destruction of the pulp due to dental caries, congenital deformity or trauma. Regenerative endodontics instead seeks to replace live tissue in the pulp chamber. The ultimate goal of regenerative endodontic procedures is to regenerate the ...
The pulp is the neurovascular bundle central to each tooth, permanent or primary.It is composed of a central pulp chamber, pulp horns, and radicular canals. The large mass of the pulp is contained within the pulp chamber, which is contained in and mimics the overall shape of the crown of the tooth. [2]
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.
If the soft tissue in the canals is still healthy enough, a special medicated filling can be put into the chamber in an attempt to keep the remaining pulp (in the canals) alive. The process of removing the pulp from the chamber is the actual pulpotomy, though the word is often used for the entire process including placement of the medication.
