“…This difficulty has been correlated with the observation of performance differences between different instrument systems (22)(23)(24). Furthermore, the evaluation of the changes in canal curvatures after instrumentation has been widely used to assess the tendency of a given technique or of the mechanical properties of a certain instrument to maintain the original anatomy of the canal or rectify its curvatures (22,25).…”

“…28 The ProTaper Universal finishing files have a greater taper at the apical part of the instrument (F1, .07 and F2, .08), leading to increased stiffness or rigidity. 29 The Mtwo group created centered preparation 1 to 4 mm from the apex in both canal types. The reason for the centered preparation seems to be the gradually smaller amount of material removed from the canal walls.…”

The aim of this study was to compare the shaping ability of a recently introduced instrument (Revo-S) in comparison with the four current instruments (HeroShaper, Mtwo, ProTaper, RaCe) in simulated root canals. Material and methods: Nickel-Titanium systems (n=15 resin in each case) were used to prepare 34-35° curved and S-shaped simulated root canals in clear resin blocks. The width of resin removal was measured by comparing the pre-and postoperative images under a stereomicroscope. The amount and direction of transportation, the centering ability and the total amount of resin removal were determined. Canal aberration incidence, preparation time, and instrument deformation were also recorded. Results: In both canal types, the RaCe group prepared canals more rapidly (P < 0.05) and created no canal aberrations.The ProTaper Universal group was significantly slower than other groups (P < 0.05) for both canal types. The tapered canal form was obtained in the Mtwo, ProTaper Universal; and RaCe groups in 34-35° curved canals; and only the RaCe group in S-shaped canals. Some deformations but no instrument fractures were observed for HeroShaper, Mtwo, and Revo-S groups. Conclusion: RaCe rotary Nickel-Titanium instruments, probably do to their triangular cross-sectional shape with alternating cutting edges and sequence encompassing a high number of instruments, exhibited a better centrally shaping and fewer canal aberrations.
