Abstract: The aim of the current literature review shows the reasons for endodontic-surgery treatment and its techniques (methods) for its realization. When conservative treatment is not possible because of post with crowns, bridges and consideration of the possibility of weakening of the remaining dental hard tissues, there are reasons for undertaking apical surgery. This can be defined as endodontic-surgery procedures that include apical resection, curettage and retrograde filling. The aim is sealing the root canal in order to eliminate microleakage of periapical tissues. In relation to this literature discusses issues related to the sealing of the root canal and updating of various cements for root canal filling. The access to the apical portion may be provided by a low-speed handpiece with fissure burs or high-energy lasers, supported by microsurgical mirror and microscope. Different ultrasonic tips are an alternative for retrograde root canal preparation. Materials that might be used are: MTA, Biodentin, IRM, EBA, I Root SP, MTA Fillapex, ProRoot Endo Sealer, EndoSequence Bioceramic Root Repair Material. Conclusion: in appropriately selected clinical cases, endodontic-surgical approach gives good and reliable results and should be preferred over the decision for extraction of the tooth and its subsequent replacement by implant therapy.
