Modern endodontic microsurgery has a high reported success rate of up to 93.5%, making it a viable treatment option in the management of periapical disease when orthograde root treatment is not possible or inappropriate. This high success rate is intimately related to advanced techniques that have allowed practitioners to overcome historical barriers to the success seen in traditional surgical endodontics. When comparing traditional root-end surgery and endodontic microsurgery there are key differences when considering the flap design, access armamentarium, size of osteotomy, instruments used and root-end material. This paper highlights such key differences and advises practitioners on the techniques and instruments used to achieve high success rates, firmly establishing non-surgical endodontic treatment as an important treatment option in well-selected cases.
