The department of dentistry that treats dental diseases inside the tooth, that is, up to the root, is called endodontics. Endodontic treatment is the most common dental treatment method applied by dentists.

It is useful to know the following in order to better understand the branch of endodontics. According to dental anatomy, the visible part of the tooth when looked from the outside is called the crown, and the invisible part, that is, the part under the crown, is called the tooth root. There are layers that make up the tooth. The layer where the gum and crown meet is called enamel. The layer under the tooth enamel is called dentin. The layer under the enamel and dentin, which is the living part of the tooth that cannot be seen from the outside, is called the pulp.This soft connective tissue is called the dental nerve.
