Orthograde retreatment may be considered when persistent pain or symptoms develop in a root canal treated tooth. Retreatment procedure involves the removal of the root canal filling, further cleaning, and refilling of root canal.[1] Several instruments and solvents, heatbearing instruments and ultrasonics have been suggested for removing root canal materials.[2–4] However, none of these retreatment methods achieves entirely clean root canal walls.[4] Nickel-titanium (Ni-Ti) rotary instruments have been used for the removal of filling materials from root canal walls, and several studies reported their efficacy, cleaning ability and safety.[4–6] However, they also have some limitations and drawbacks. Some limitations of Ni-Ti rotary instruments are: complicated file systems, tedious irrigation, canal transportation, unexpected file separation, mismatch with three-dimensional shape of the root canal.[7] The SelfAdjusting File (SAF) System was designed to overcome ORIGINAL ARTICLE
