• The system is comprised of three shaping (SX, S1 and S2) and three finishing (Fl, F2 and F3) files.
• A maxillary second molar and a mandibular second premolar were shaped with these files, and smooth uniformly tapered canals were created more easily than with stainless steel hand files.
• During use of NiTi rotary files, it is necessary to consider their potential for breakage.
• In order to prevent breakage, these files have a unique design, including multiple tapers, a convex triangular cross-section, a continuously changing pitch and helical angle, and a modified guiding tip.
