Failure of root canal therapy is usually due to re-infection of the root canal system. In most of these cases, an endodontic retreatment is indicated. Patients with persisting apical periodontitis frequently are referred to an oral surgeon for apical surgery, although endodontic retreatment would have been possible in a majority of these cases. When endodontic retreatment is not possible or does not resolve the patient's problems, surgical apicoectomy or extraction might be the only possibilities left. Apical surgery is usually performed by an oral sugeon or by a specially trained dentist. In most surgical clinics beveled resection, followed by an preparation and restoration is performed. New developments, such as microscopic sugery, ultrasonic preparation and newly developed restorative materials are described in this article. Since there is a lack of well-designed comparative clinical studies, no definite conclusions can be drawn with regard to the clinical value of these modern techniques.
