A root canal is the naturally occurring anatomic space within the root of a tooth.It consists of the pulp chamber (within the coronal part of the tooth), the main canal(s), and more intricate anatomical branches that may connect the root canals to each other or to the surface of the root.
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).
Examples of this are undercuts, slots/grooves or root canal posts. In some cases this may necessitate excessive amounts of healthy tooth structure to be removed. Hence, alternative resin-based or glass-ionomer cement-based materials are used instead for smaller restorations including pit and small fissure caries.
Most of the time, the crown of the abutment teeth has to be removed to allow space for placement of overdenture without interfering the bite. Therefore, the pulp has to be removed. If the root canals of the abutment teeth are obliterated, endodontic treatment is not required. Teeth with non-negotiable root canals should not be selected as ...
After endodontic therapy has been executed, or re-executed, successfully, and the canals can no longer provide a nutrient-rich habitat for microbes, [31] the issue of bone healing comes into focus. Ostensibly, then, for regeneration to occur, the root canal system must have been decontaminated and further access to microbial invasion must be ...
Internal resorption is defined by the loss of intraradicular dentin and tubular dentin from within the middle and apical thirds of the root canal(s). It may also present as an incidental, radiographic finding. Radiographically, a radiolucent area of uniform density within the root canal may be visible with well-defined borders.
Tooth is mobile or becomes mobile during procedure; Tooth is horizontal or distoangular impacted; Medically compromised patients for example immunocompromised; Patients who are predisposed to local infection for example if they have undergone radiotherapy in the area they may have poor healing.

Dental avulsion is a true dental emergency in which prompt management affects the prognosis of the tooth. [14] Replantation of the tooth within 15 minutes is associated with the best prognosis as periodontal ligament (PDL) cells are still viable.
