Bacteria are crucial for the development of apical periodontitis. The microorganisms within the root canal are predominantly composed of slow‐growing anaerobes. Clinical signs and symptoms of infection such as pain, swelling or exudation are caused by specific bacteria that are capable of interfering with the host defense. A primary goal of endodontic treatment is the elimination of infection from the root canal system. Predictable management depends on an aseptic technique, biomechanical cleaning with antimicrobial irrigants such as sodium hypochlorite solution in conjunction with EDTA solution and antibacterial dressing with calcium hydroxide. The prognosis of treatment depends on many factors including the preoperative status of the periapical tissues, the level of the root filling in relation to the apex and, importantly, the presence of infection at the time of root filling. Failures are usually associated with errors in clinical technique. However, even when treatment is performed to a high standard, failures may occur due to intraradicular or extraradicular infection, cysts or a foreign body reaction.
