There are several types of endodontic treatments, each designed to address specific issues related to dental pulp and root canal infections. The most common type of endodontic treatment is root canal therapy, which involves removing the infected or inflamed pulp, cleaning the root canal, and sealing it to prevent future infection. In some cases, endodontic retreatment may be necessary if the initial treatment does not successfully resolve the infection or if a new infection arises. Another type of endodontic treatment is apicoectomy or root-end resection, which is usually performed when a root canal treatment hasn't been successful, or an infection develops. This procedure involves removing the root tip and the infected tissue. Additionally, there is a pulp capping procedure, a preventative treatment used to avoid root canal therapy when a pulp exposure has occurred.
