What Is a Root Canal?

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. A root canal is a dental procedure aimed at treating infection at the center of a tooth, known as the pulp. This treatment is necessary when the pulp becomes infected due to decay, repeated dental procedures, or a crack or chip in the tooth. The primary goal of a root canal is to remove the infected pulp, clean and disinfect the inside of the tooth, and then fill and seal it to prevent future infections1 2.

Procedure Overview

The root canal procedure typically involves several steps. Initially, the dentist or endodontist will take an X-ray to assess the extent of the infection. The tooth is then isolated with a rubber dam to keep it dry and free from saliva. An opening is made in the crown of the tooth to access the pulp chamber and root canals. The infected pulp is removed, and the canals are cleaned and shaped using specialized instruments. The canals are then filled with a biocompatible material, usually gutta-percha, and sealed with adhesive cement8.

Treatment Protocols

Root canal treatments can be performed in one or two visits. A study comparing one-visit and two-visit treatments found that both protocols effectively reduced bacteria and endotoxins, although two-visit treatments were more effective in reducing endotoxins1. The choice between one or two visits may depend on the complexity of the case and the patient’s specific needs.

Irrigation Techniques

Irrigation is a crucial part of the root canal procedure, as it helps to disinfect the canals and remove debris. Various irrigants, such as sodium hypochlorite (NaOCl) and chlorhexidine, are used. Studies have shown that different concentrations of NaOCl (0.5% vs. 3%) result in similar clinical outcomes, although higher concentrations may lead to more postoperative swelling2 9. Additionally, techniques like ultrasonic activation can enhance the effectiveness of irrigation by improving the removal of debris and bacteria6 7.

Impact on Oral Health

Root canal treatment significantly improves oral health-related quality of life by alleviating pain and preventing further dental issues. Different treatment protocols, such as manual versus reciprocating file systems, have been shown to enhance patients’ quality of life, with some protocols offering better outcomes in terms of psychological comfort and social disability5.

Conclusion

Root canal treatment is a vital dental procedure for saving teeth with infected pulp. It involves removing the infection, cleaning and shaping the canals, and sealing them to prevent future issues. Advances in irrigation techniques and treatment protocols continue to improve the effectiveness and patient experience of root canal therapy.
