Shaping the root canals gradually increasing from apical to coronal is one of the most important steps for sufficiently cleaning and filling the root canals.[1] The nickeltitanium (NiTi) alloys having super flexibility are useful in minimizing the canal irregularities such as ledge, zip and perforations that may occur during shaping the narrow and curved canals.[2,3] Besides these advantages of the NiTi alloys, they have an important disadvantage that they have high fracture incidence due to the cyclic fatigue in the narrow and curved canals. Nowadays, the NiTi rotary file systems (Conventional, R-Phase, M-Wire, and Gold-Wire NiTi) made of various alloys and with various kinematics (continuous rotation, reciprocation, and adaptive motion) are recommended for maintaining the original canal form during shaping the root canals.[4,5] Twisted File Adaptive (TFA; SybronEndo, Orange, CA, USA) is a system that operates with its specific endodontic motor (Elements Motor; SybronEndo) and aiming to combine the advantages of rotation (continuous 360° clockwise motion) and reciprocation (clockwise and counterclockwise motion at different degrees). In case that there is no stress in the canal, the file completes its 600° clockwise rotation, then stops and continues rotational motion. As the stress on file increases, Elements Motor modifies the motion up to 370° clockwise and 50° clockwise motion depending on the level of stress.[6] As a result of kinematic modification, the stress on file decreases through the counterclockwise motion of file, when ORIGINAL ARTICLE
