Quick Reference

The process of removing an infected, inflamed, or necrotic pulp and filling the residual space with an inert material. Access must first be gained to the pulp chamber and root canal system; the pulp canals are then measured and the pulp tissue and any infected material removed; the canals are then shaped, irrigated, and cleaned of debris; the root canals are obturated with a root filling material such as gutta-percha and a sealant, and finally a coronal seal placed to prevent bacteria from the mouth entering the root canal system.
