Endodontic treatment includes clinical science and basic research (dental diagnosis and treatment) of normal dental pulp, etiology, diagnosis, prevention, and treatment of diseases and injuries related to dental pulp and related root apex conditions. Endodontics has come a long way in the past decade, and its practical aspects have greatly improved the quality of dental care. From a clinical point of view, endodontic treatment involves the preservation of some or all of the pulp, or in irreversible pulp disease, the removal of all pulp. This includes infection with irreversible inflammation, and pulp tissue.
Not only the treatment when the pulp is still present, but also the preservation of the tooth that is ineffective for non-surgical pulp therapy, or the diagnosis and treatment of the pulp that has developed new lesions; for example, root canal retreatment is required , or apicectomy, etc. therapy. Endodontics is one of the most common procedures in dental treatment. If the pulp (which contains nerves, arterioles, venules, and lymphatic and fibrous tissue) is diseased or injured, endodontic treatment is required to preserve the tooth.
