An Apicoectomy, or Root-End Resection, is the removal of the root tip and the surrounding infected tissue of an abscessed tooth. This procedure may be necessary when inflammation and infection persists in the area around the root tip after root canal therapy or root canal retreatment.
Who performs root canal retreatment? - Endodontic or root canal retreatment can be more complicated and technically challenging than initial treatment, and is generally carried out by root canal specialists, "endodontists", dentists who have taken specialty training in the diagnosis and treatment of root canal problems. Most modern endodontic procedures are performed with the use of microscopes to allow the proper degree of precision and sophistication needed to ensure success.
