“…It has been stated that the resistance of rotary instruments to cyclic fatigue decreases with increasing instrument diameters and tapers [7,21]. In the present study, D-RaCe DR2 (size 25, 0.04 taper) showed greater cyclic fatigue resistance than the ProTaper D3 (size 20, 0.07 taper) and Mtwo R2 (size 25, 05 taper).…”

“…The usage of rotary instruments in the retreatment process presents the advantage of reduced clinical time [20]. However, Inan et al [21] stated that a well-compacted filling material presents resistance to instruments. Therefore, the retreatment files chosen for this procedure must possess greater resistance to cyclic fatigue and torsional forces.…”

“…Based on this finding, it can be concluded that the increase in tapers of retreatment instruments decreases the resistance to fracture. Inan et al [21] evaluated the cyclic fatigue resistance of R-Endo, Mtwo, and ProTaper retreatment instruments in non-immersion conditions, and they found that R-Endo R3 (size 25, 0.04 taper) instrument showed greater cyclic fatigue resistance than the ProTaper and Mtwo retreatment instruments. Also, there was no significant difference between the ProTaper and Mtwo instruments in their study.…”

Objective:To compare the cleanliness of oval cross-sectioned root canals after using different supportive techniques for removal of root canal filling material as part of retreatment process. Methods: One hundred mandibular canine teeth with flat oval cross-sectioned canals were instrumented up to #40.06 and obturated using the warm vertical compaction technique. Removal of the gutta-percha and sealer was performed using the D-RaCe nickel-titanium retreatment instruments. The roots were randomly divided into four groups of 25 teeth, and the activation processes were applied: XP-endo Finisher (XP), EndoActivator (EA) and IrrıSafe (IS). Conventional needle irrigation (CI) was used as the control group. The teeth were sectioned, and digital images were captured. The photographs were analysed using AutoCAD software regarding the area of residual root filling. Kruskal-Wallis and post hoc Dunn's tests were performed for statistical analysis. Results: There was significantly less gutta-percha and sealer remnant in the XP group than in the other groups (P<0.05). The CI group contained significantly more gutta-percha and sealer remnant than the other groups (P<0.05). The apical third of the CI group had significantly more residual gutta-percha and sealer when compared to that of the other groups (P<0.05). Conclusions: Within the limitations of this study, the amount of gutta-percha and sealer in the XP group was lower than that in the EA, IS, and CI groups.
