When do you need a Root Canal?| Procedures and More

Endodontic or root canal therapy is a set of sessions of treatment for the infection in the pulp region of a tooth or teeth. This treatment leads to the elimination of infection and the subsequent protection of the treated tooth or teeth from further microbial invasion.


Root canals and the pulp chamber linked with it is the physical cavity kind of structure inside a tooth. This is filled up with nerves, blood vessels and certain other tissues and cellular stuff. Put together, this substance is called the dental pulp. Root canal treatment constitutes taking out of this dental pulp, shaping up, cleaning and decontamination of this cavity. Further treatment, also a part of the root canal procedure, filling up of this cavity again. The substance used for this is an inert filling like gutta-percha. An epoxy resin is used to cement in the gutta-percha in a few of the root canal treatments. Endodontic treatment is primary and secondary lines of procedures which also may include periarticular surgery. This surgery is used to salvage teeth which still can be de-infected and restored.


In the event that a tooth or teeth are in such a condition that infection in times to come may be inevitable, a pulpectomy is recommended. This involves removal of the pulp tissue. At times, some swelling may already be present as a symptom of prevalent infection. To cure this, the dentist drills into the pulp chamber, removes the infected material there and proceeds to even drill away the nerve out of the root canal. Nowadays, newer forms of techniques  have been introduced to better this procedure.

These days, the step back, circumferential filing, incremental, anti-curvature filing, step down, double flare, crown down pressureless, balanced force, canal master, apical box, progressive enlargement, modified double flare, passive stepback, alternated rotary motions and apical patency techniques have come to the fore. During the treatment, the root canal is filled with an irrigant. This could be a solution such as one with less than five percent sodium hypochlorite; six per cent sodium hypochlorite with surface modifiers;  two percent chlorhexidine gluconate; 0.2 percent chlorhexidine gluconate plus 0.2 per cent cetrimide.
