Apical surgery failures: Extraction or re-surgery? Report of five cases

Apical surgery (AS) is considered as the last attempt to save teeth which cannot be treated with conventional endodontic approach. The main goal of apical surgery is to create a barrier between the root-canal system and the peri-radicular tissues by means of a tight root-end filling after resection. However, failures in this treatment is usually result with tooth loss. In such cases surgical re-treatment would take into consideration as viable alternative. In this case series, successful ARs that performed in ten teeth of five patients who applied for extraction after an unsuccessful apical surgery, were presented. It is pointed that if appropriate surgical and endodontic intervention is performed and adequate apical obturation is provided with retrograde filling, teeth can be treat without extraction.
