What is Root Canal Treatment (RCT)?
Root canal treatment is the removal of inflamed and/or infected dental pulp tissue from the root canal system, shaping and filling the root canals of a diseased tooth. The key factor in the development of pulpal inflammation and breakdown of the supporting tissues of the tooth (periradicular tissues) is the presence of bacteria. These endodontal infections (infections within teeth) are usually characterized by loss of integrity of the crown, invasion by bacteria, and destruction of enamel, dentine, and eventual pulpal involvement. Dental caries, trauma, tooth surface loss, and microleakage around tooth fillings can lead to endodontal infection. In situations where there has been periradicular breakdown, root canal treatment will result in the return of the health of the periradicular tissues. Ultimately, root canal treatment preserves teeth as functional units within the dental arch. Continue reading
