An analysis of the topic of the root canal

It's common to feel a bit of a pinch in the area when the needle goes in. In case of doubt, it is essential to discuss the clinical case with a more experienced professional, as in some cases it is not easy to determine the differential diagnosis of diseases of non-endodontic and endodontic origin. Instead, the goal of the procedure is to save a tooth that is severely infected. Several studies reported that root canal preparation and obturation short of the radiographic apex were associated with a better prognosis 18 - Apical constriction: location and dimensions in molars—a micro-computed tomography study. The reference list of selected studies was critically assessed by both examiners. Success rate of endodontic treatment of teeth with vital and nonvital pulps. Siqueira-Jr JF.
In this sense, AP cannot be correctly identified by periapical radiography only. When there is pulp necrosis, bacteria and their by-products as well as infected dentin debris may remain in the most apical portion of the root canal, and these irritants jeopardize apical healing.
In these cases, highest success rates were achieved when obturation ended at 0—2 mm short of the radiographic apex. An email alert was created in all databases for new references.
If the tooth cannot be saved, the next best option is an implant.

The treatment does not cause pain; it helps to alleviate it. There is only one answer to this question and that is with modern electronic apex locators. Endodontics Root canal treatment: Where does the apex end? Determining the optimal obturation length: a meta-analysis of literature. Microorganisms with different characteristics structural, metabolic and pathogenic reaching the periapical region stimulate the inflammatory and immunologic responses. In the same direction, the properties of calcium hydroxide stem from its dissociation into calcium and hydroxyl ions and the action of these ions on tissues and bacteria explains biological and antimicrobial properties of this substance Various radiolucent images may be associated with the apex, without being diseases of microbial origin and could be misinterpreted as AP 5 - 7.
To conserve the tooth a revision of the endodontic treatment becomes necessary, because otherwise persistent microorganisms or secondary infections mainly caused by insufficient coronal restoration can lead to loss of the tooth.
Diagnostic and clinical factors associated with pulpal and periapical pain.
Root canal treatment steps
The infection of the dental pulp mobilizes microorganisms to develop in apical direction, to invade and colonize the periapical tissues. Laser root canal procedures are a controversial innovation. Various factors may affect tooth survival, such as dental caries, periodontal disease and RCT. The current moment of endodontic science is promising in view of all the knowledge acquired over the last few years Sometimes the canal filling does not fully extend to the apex of the tooth, or it does not fill the canal as densely as it should. Underfilling, overfilling, and root perforations were detected in Endodontic Science. This means less post-operative pain for your patients and a better and faster healing tooth. Braz Dent J Deficient attendance may be responsible for severe consequences and sequels, which impairs the prognosis, and may result in serious judicial questions Teeth with obturation material that did not reach within 4 mm of the radiographic apex or could not be isolated with a rubber dam were excluded from the study. The differential diagnosis of diseases of non-endodontic and endodontic origin should always be made carefully.
Sampling Procedure All samples were collected under strictly aseptic conditions. Read now How painful is it? The infection of the dental pulp mobilizes microorganisms to develop in apical direction, to invade and colonize the periapical tissues.
In the s, this theory was discredited, but the theory was recently revived by a book entitled Root Canal Cover-Up Exposed which used the early discredited research, and further complicated by epidemiological studies which found correlations between periodontal disease and heart disease, strokes, and preterm births.
After a few weeks, your dentist will finish the treatment by placing a permanent crown or a similar type of restoration on the top of the tooth. If needed, prescription drugs, such as codeine, are available.

Obtained biospecimens: LK. The reality of the situation is a little more complex. Other etiologic agents should also be correlated as potential periapical aggressors. On the basis of biologic and clinical principles, instrumentation and obturation should not extend beyond the apical foramen 18 - 22 , 27 - Recommended treatment is either to redo the root canal therapy if possible, or extract the tooth and place dental implants. J Endod ;— The RCT success criteria and its prevalence should be routinely reevaluated. Endodontics Root canal treatment: Where does the apex end? Wu et al. Imaging resources have been routinely used before, during and after dental treatment. Table 1 Comparison of microorganisms in root-filled teeth with periradicular lesions using cultural methods and 16S-rDNA clone library analysis. No studies were identified by email alert up to December Factors affecting the long-term results of endodontic treatment.
