If re-root treatment is not possible, will not correct the problem or patient factors prevent it,<unk>  is indicated. Anatomical deviations preventing access or preparation of canal, including root-canal calcification, pulp stones, severely curved roots, bifurcations, secondary roots, lateral canals, delta apexes, internal and external resorption resistant to conventional treatment and an incomplete apex, may prevent the complete cleaning and preparation of the canal. Procedural errors include the formation of ledges, perforation of the root or floor of the pulp chamber, extruded root filling material, file breakages, or underfilled canals. These are only indications for<unk>  if they cause persistent periapical radiolucency, swelling and pain. Exploratory surgery that identifies possible root fractures or perforations indicates<unk> . A biopsy may be used in suspicious or non-healing lesions, or when a patient has uncharacteristic signs and symptoms in periapical areas.
