1.Changed taper, extremely flexible
2.Including Shaping Files and Finishing Files

The ProTaper 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 ProTaper 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, ProTaper 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.
Furthermore, the files are combined with an EndoTecnika motor,
programmed to allow torque selection for each ProTaper file, which
increases safety. Consequently, it is believed that the ProTaper
system is very useful in preparing root canal treatment.
