Apicoectomy involves surgical management of a tooth with a periapical lesion which cannot be resolved by routine endodontic treatment. Because the term “apicoectomy” consists of only one aspect of a multifaceted series of surgical procedures, i.e removal of root apex, the terms “periapical surgery” or “periradicular surgery” are more apposite. It must only be applied in specific situations. Endodontic treatment failures can be related to: extra-radicular infections such as periapical actinomycosis; to foreign body reactions that can be caused by endodontic material extrusion; to endogenous cholesterol crystal accumulation in apical tissues and unresolved cystic lesion.
