Pulp Tissue Removal
The first step of endodontic treatment involves the removal of infected or necrotic pulp.
Under local anesthesia and using appropriate drills, an opening is made in the back of the affected tooth (in the case of a previous tooth) or in the crown (in the case of molar or premolar teeth), through which is removed all dental pulp tissue or remains of sealing material from previous endodontic treatments.
Irrigation (Disinfection) and Root Canal Filling
After the pulp or remains of sealing material from previous endodontic treatments has been removed, the pulp chamber and root canal system present in the roots are properly disinfected in order to eliminate all bacteria. After conveniently prepared, the canals are able to receive the filling, normally performed with Gutta-Hanger, a derivative of vegetable resin. When the canals are filled, the tooth is hermetically sealed with cement and restored in order to regain its natural appearance.
As the duration of endodontic treatment depends on several factors, in situations where it is not possible to perform the complete treatment in only one consultation, a temporary restoration is placed in the access opening, with the purpose of protecting the tooth between consultations.
