Root End Surgery
Sometimes a non-surgical approach for root canal therapy is not possible. Skillful diagnosis in endodontic surgery requires accurate determination of the reasons for endodontic failure. Most common causes for failure are: unusual, complex and undetectable root canal anatomy, accessory canals that cannot be treated conventionally, or a fractured root. Other factors which may require a surgical approach, include the presence of a post which cannot be removed, calcification of the canals, or obstruction due to a separated instrument. Most of these cases can be successfully treated with endodontic surgery. The goal of all endodontic surgery is to remove disease, prevent it from recurring, and to create an environment in which healing may occur. The surgical procedure itself is done in the dental office, under local anesthetic. It can take approximately two or three hours, and most patients return to work after the procedure. Some of the most common endodontic surgeries are: Apicoectomy or Root-End Resection, Hemisection, Root Amputation.
