Endodontic surgery: Influencing factors

Introduction: Periapical surgery has been indicated for the treatment of teeth with periapical lesions when disease persists despite orthograde periapical root canal treatment, a surgical approach may be indicated when periradicular pathosis cannot be resolved with a non-surgical approach.Objective: To analyze the literature on influencing factors on endodontic surgery, particularly surgical considerations, root-end preparation, root-end filling, and treatment success.Methodology: The search for articles was performed by a researcher in the Pubmed database.Keywords used were "endodontic surgery", "apicoectomy", "flaps", "osteotomy", "preparation of the root or apical end", "retrograde obturation" and "treatment success of endodontic surgeries".Results: The surgical considerations, such as that the flaps can be full thickness or divided and a fundamental part is to achieve a good esthetic in the healing.In the osteotomy the important thing is the diameter in which it is performed, the larger the diameter, the more the healing process will be.Then a resection of the root end will be performed, mainly the apical 3 mm and 3 mm intraconducts will be prepared in a retrograde way with ultrasound tips.The obturation will be performed in a retrograde way where the most used materials for this step in the procedure are MTA and Biodentine.The success rate of this treatment is over 80%.Conclusion: Endodontic surgery treatment is a highly complex and complicated procedure.In order to perform this treatment, good planning with CBCT studies should be carried out.
