Success rates for root-canal treatment range from 47 to 97 percent; failures may be due to spaces in the root-canal filling, a root filling which is too short or a preexisting periapical lesion. [3] Treatment options are nonsurgical root-canal re-treatment or periradicular surgery.
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.
Exposure of the pulp causes pulpitis (an inflammation which can become irreversible, leading to pain and pulp necrosis, and necessitating either root canal treatment or extraction). [1] The ultimate goal of pulp capping or stepwise caries removal is to protect a healthy (or reversibly inflammed) dental pulp, and avoid the need for root canal ...
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.
The success rate of root canal treatment also depends on the degree of disease (root canal therapy for irreversible pulpitis has a generally higher success rate than necrosis with periapical abscess) and many other technical factors. [10]: 77–82

When the root is incompletely formed in adolescents and an infection occurs, apexification can be performed to maintain the tooth in position as the roots develop. In case of non-vital pulp: 1. Isolate the tooth with a rubber dam 2. perform root canal treatment. 3. Mix MTA and insert it to the apex of the tooth, creating a 3 mm thickness of ...
If the condition is discovered before perforation of the root has occurred, endodontic therapy (root canal therapy) may be carried out with the expectation of a fairly high success rate. Removing the stimulus (inflamed pulp) results in cessation of the resorptive process.
