“The endodontic treatment consists in the removal of the pulp tissue both at the coronal level and at the root level and in the replacement of the removed tissue with a permanent filling in gutta-percha and root canal cement, after an adequate shaping of the root canals.”

The dental pulp contained within the tooth is commonly referred to as the nerve.

Following a deep caries and relative bacterial contamination, or following a trauma, the pulp undergoes inflammation and infection. This is the clinically often painful picture of pulpitis.

Acute or chronic inflammation can propagate outside the apex of the tooth root causing lesions defined as abscess or granuloma.

In these cases, endodontic treatment is absolutely necessary, being the only alternative to extracting the dental element in question.
