Dental - Root Canal Treatment (RCT)
Root Canal Treatment (RCT)

Root canal treatment is a method to clean roots by gaining access from the tooth with the help of Dental instruments and specific equipments. When the carious lesion reaches pulp (where all blood vessels are present), then the only option left is RCT. Sometimes carious lesion even extend from root to apex (where root ends), then extraction is advisable as RCT will have poor prognosis in this case.
Time taken or sittings involved during RCT depends upon the extent of infection in tooth.

Steps involved in RCT are as follows:

Gaining Access to Root canals: Access from the surface of the tooth(crown) is gained with the help of Drilling instrument . Normally there are 3 canals in molars, 2 canals in premolars and 1 canal in Incisors and canine. Number of root canals can vary in tooth from person to person, it is never fixed.
Cleaning and Shaping of Root canals: Once the access is gained, then with the help of instrument known as files as shown in figure, Canals are cleaned. To avoid friction and proper cleaning disinfectant solution known as sodium hypochlorite is used. It removes all the debris and infection from the canals and makes them sterile. It usually takes 2 sittings, but if infection is less than it can be completed in 1 sitting also. After the thorough cleaning, temporary filling is placed in tooth and patient is asked to come after 2 days.

Filling of Root canals: Once the canals are cleaned, and then canals are properly dried with the help of paper points and filled. Canals are filled tightly with Gutta percha points (GP points). After filling of root canals, Permanent filling is placed in tooth; normally permanent filling does not last long. Always Crown is mandatory after RCT as tooth becomes weak from inside. To avoid further fracture of tooth, crown is mandatory.
