The second release of the root canal will be placed in the pulp area. Root canal therapy, also known as endodontics, is a procedure used in dentistry to treat pulp necrosis and root infection. The necrotic material in the tooth can be removed and properly inactivated, anti-inflammatory, filled, and the undesirable irritation of the root canal contents on the surrounding tissues can be removed before the tooth is restored or braces are placed. The root canal procedure requires cleaning of the tooth’s nerve, which is in the pulp area. Usually, an inactivator is first used to kill the pulp, or the dead pulp is removed directly, and anti-inflammatory medications are placed to eliminate inflammation of the deep root canal and sidewall colonies. The root canal is then filled and the tooth is restored or crowned. The purpose of this second placement is to de-inflame the pulp, so the medication will be placed and act on the pulp area.
