diseased tissue is removed at this point through curettage. The root end resection is carried out, removing 3mm apically. The canal(s) is then obturated, and the flap is sutured. There are a number of root-end filling materials available, including zinc oxide eugenol cements, and mineral trioxide aggregate. Complications that may arise include: pain: anti-inflammatory agents or analgesics should be taken swelling: intermittent ice will aid in eradicating this. Swelling resolves usually within 24–48 hours. ecchymosis (discolouration): this will often occur distant from the surgical site paraesthesia: usually transient as a result of inflammatory swelling, and sensation will return to normal in 4 weeks serious infection is rare, but can be treated with antibiotics, which should be administered with caution to avoid bacterial resistance maxillary sinus perforation Other procedures Other non-surgical endodontic procedures include pulp capping, pulpotomy, apexification, and pulpal regeneration. Hemisection, where a root and its overlying portion of the crown are separated from the rest of the tooth and optionally removed, is another (non-periradicular) endodontic surgery. Tools Microsurgical endodontics, the use of magnification devices such as microscopes, and dental loupes, has been widely accepted among endodontists and practitioners; its use is believed to increase accuracy and visualization in the operating field. However, a Cochrane review in 2015 found no evidence to determine whether there is a difference in the outcome of a procedure done by magnification devices or a conventional procedure done with no magnification. The American Association of Endodontists strongly encourages its members to pursue the use of an oral microscope to ensure the highest level of excellence. The use of a CBCT is also becoming the standard of care. Training Endodontists are specialist dentists with additional training, experience and formal qualifications in endodontic treatment, apicectomies, microsurgery, and dental emergency and trauma management. Endodontics is recognized as a specialty by many national dental organizations including the Dental Board of Australia, British General Dental Council, American Dental Association, Royal College of Dentists of Canada, Indian Dental Association, and Royal Australasian College of Dental Surgeons. Australia In Australia, endodontics is recognized as one of the thirteen registered dental specialties. In addition to a dental degree, Endodontists have an additional three years of postgraduate University training in the area of Endodontics to be recognized and registered by the Dental Board of Australia. A general dentist is permitted by law to perform endodontic treatment, but must be competent in the skills required
