Endodontia is a branch of dentistry that deals with the study and treatment of the dental pulp, which is the soft tissue inside teeth that contains nerves and blood vessels. This specialized field focuses on diagnosis, prevention and treatment of disease and injuries to the tooth pulp and surrounding tissues. Endodontic treatment or root canal therapy, is the most common procedure in this field, it involves removing the infected or damaged pulp, cleaning, disinfecting, and shaping the root canals, and then filling and sealing them. This allows the patient to keep their natural tooth and avoid the need for an extraction. In addition to root canal therapy, endodontists can also perform other procedures such as Apicoectomy, which is the removal of the tip of the tooth root, and treat traumatic dental injuries. Endodontists are dentists who have completed additional specialized training in endodontics after obtaining their dental degree and passed the National Board and specialty board examinations. They are also expert in difficult or complicated case of endodontic treatment.
