Overview and Importance of Endodontics - Endodontics encompasses the study and practice of the basic and clinical sciences of dental pulp. - It involves the diagnosis, prevention, and treatment of diseases and injuries of the dental pulp. - Endodontics includes preserving teeth with irreversibly inflamed and infected pulpal tissue. - Treatment is required to save the tooth if the dental pulp becomes diseased or injured. - Endodontic treatment is one of the most common dental procedures. - Endodontists play a crucial role in preserving natural teeth through root canal treatments. - Endodontists are specialised in endodontic therapy and can provide advanced treatments. - Endodontists are members of the American Association of Endodontists. - Endodontists use microscopes during treatment to preserve tooth structure and avoid iatrogenic damage. - Endodontists use CBCT (3D imaging) for diagnosis and treatment planning.

Procedures - Root canal treatment is a dental procedure used to treat infected tooth pulp. - It is required when the dental pulp is irreversibly damaged. - Root canal treatment can also be done before placing post-retained crowns and overdentures. - Periradicular surgery involves the root surface and includes procedures like apicoectomy and root resection. - Other non-surgical endodontic procedures include pulp capping, pulpotomy, apexification, and pulpal regeneration. - Hemisection is another non-periradicular endodontic surgery where a root and its overlying portion of the crown are separated and optionally removed. - Microsurgical endodontics, using magnification devices like microscopes and dental loupes, is widely accepted among endodontists.

Root Canal Treatment - Root canal treatment is used to treat infected tooth pulp. - Bacteria entering the pulp through deep cavities or failed fillings can cause this. - It involves removing the damaged and infected pulp, shaping and cleaning the root canal system, and filling and sealing it. - A direct or indirect restoration is placed after the root canal treatment. - Instrument fractures and sodium hypochlorite accidents can occur during root canal treatment.

Periradicular Surgery - Periradicular surgeries involve the root surface and include procedures like apicoectomy and root resection. - An apicoectomy is a surgical procedure where the apex of a root is resected. - It is done when a previous root canal treatment fails and re-root canal treatment is not possible. - Local anaesthesia is used for improved visualization during the procedure. - Complications that may arise include pain, swelling, ecchymosis, paraesthesia, and infection.

Education and Training - Endodontists are specialist dentists with additional training and experience in endodontic treatment and surgeries. - They receive formal qualifications in endodontics, apicectomies, microsurgery, and dental emergency and trauma management. - Endodontics is recognised as a specialty by national dental organizations in various countries. - In Australia, endodontics is recognised as one of the thirteen registered dental specialties. - Dentists in the United States must undergo 2-3 years of postgraduate training to become an endodontist. - American Dental Association (ADA) accredited programs for endodontics are a minimum of two years long. - After completing the training, dentists are eligible to sit for the American Board of Endodontology examination. - Successful completion of board certification results in Diplomate status in the American Board of Endodontics.
