“…To date, no previous study has compared canal transportation of ProTaper and XP-endo Shaper. Aksoy et al evaluated dentinal microcracks after root canal preparation with ProTaper Universal, XP-endo Shaper and Reciproc Blue using micro-computed tomography and observed that ProTaper Universal resulted in signi cantly higher number of microcracks [23]. In the present study, ProTaper showed higher canal transportation and lower centering ratio, which was in agreement with the results of Shah,…”

Background: Cleaning and shaping of the root canal system is important in an endodontic treatment. Canal transportation is a common procedural error in preparation of curved canals. This study aimed to compare the canal transportation and centering ratio of two rotary files in curved canals using cone-beam computed tomography (CBCT). Methods: 44 extracted human mandibular first molars with mature apices and apical curvature of 10° to 30° were selected. The samples were randomly divided into two groups (n=22) with similar curvature. The canals were prepared with ProTaper and XP-endo Shaper file systems according to the manufacturers’ instructions. CBCT images were captured using Cranex 3D CBCT system before and after root canal preparation, and canal transportation and centering ratio of the files at 3, 4 and 5 mm from the apex were calculated. Data were analyzed and compared between two groups using independent t-test at 0.05 level of significance.Results: The ProTaper Universal caused greater canal transportation and had lower centering ratio than XP-endo Shaper in both mesiodistal and buccolingual directions at all levels from the apex. The difference between two groups regarding transportation was significant at all levels from the apex in buccolingual direction (P<0.05) except for 3 mm from the apex (P>0.05). The difference between two groups regarding centering ratio was not significant (P>0.05) in mesiodistal direction at all levels except for 4 mm from the apex (P<0.05). Conclusion:The ProTaper Universal causes greater canal transportation in both buccolingual and mesiodistal directions than XP-endo Shaper.

“…eir investigation concluded that none of the used rotary systems caused new microcracks formation or propagation of existing microcracks [20]. Furthermore, our results contradict the findings of Aksoy et al; their study concluded that PTU induced more microcracks than XPES [21]. is disagreement might be attributed to differences in methodology; in our study, the file was tested and used at body temperature (37°C) throughout the instrumentation.…”

Aim. To evaluate dentinal microcrack formation on root canals instrumented, continuously in the body temperature, with XPendo shaper (XPES) and ProTaper Universal (PTU), by means of microcomputed tomographic (micro-CT) analysis. Methodology. Nineteen mesial roots with two separate canals (Vertucci Type IV) of extracted mandibular molars were used in this study. e root canals (N � 38) were divided into 2 groups. Group 1 (n � 19): all MB canals were instrumented with XPES. Group 2 (n � 19): all ML canals were instrumented with PTU. All roots were scanned with micro-CT before and after instrumentation. Two precalibrated examiners evaluated the cross-sectional images of each sample with DataViewer program. e dentinal microcracks (complete and incomplete) were counted in each third of the root for the preinstrumentation and the postinstrumentation images. Wilcoxin signed-rank and Mann-Whitney U tests were used for statistical analysis at a significance level of P < 0.05. Results. e number of microcracks increased significantly (P < 0.05) after instrumentation with XPES in the middle and cervical thirds. e number of microcracks increased significantly (P < 0.05) after instrumentation with PTU in the cervical third only. ere was no significant difference between the groups in the cervical and apical thirds. In the middle third, the XPES induced more incomplete microcracks than PTU (P < 0.05). Conclusion. Within the limitations of this study, there was no significant difference in the dentinal microcrack formation between XPES and PTU in the apical and cervical thirds of the root. However, XPES instrumentation induced more incomplete microcracks than PTU in the middle third of human roots.

“…Reciproc Blue (VDW, Munich, Germany) and WaveOne Gold (Dentsply Maillefer) represent the commercially available single-file reciprocating systems. During the fabrication of Reciproc Blue, an innovative heating process is utilized to modify the molecular structure of the material to improve its flexibility and resistance to cyclic fatigue [14].…”

“…So far the results are controversial. De-Deus et al [ 9 – 12 ] and PradeepKumar et al [ 13 ] showed that root canal preparation does not cause dentinal cracks when evaluated by CT scans, whereas the results of Aksoy et al [ 14 ] and Bayram et al [ 15 ] indicate just the opposite. In general, microscopic studies report a higher number of cracks than CT scans, which raises the possibility that sectioning itself distorts the results.…”

The potential mechanical impact of different rotary systems used for root canal preparation has been a matter of debate for long. The aim of this study was to explore the incidence of dentinal cracks after root canal instrumentation with various rotary systems, in vitro. One hundred and eighty intact lower central incisors were selected and randomly divided into fourteen treatment groups (n = 12/group) and a control group (n = 12). After decoronation, the root canals were instrumented with fourteen different rotary systems (E3, E3 azure, NT2, Hyflex CM, Hyflex EDM, 2Shape, OneCurve, ProTaper Next, ProTaper Gold, WaveOne Gold, Mtwo, Reciproc Blue, TF adaptive, K3XF). All roots were horizontally sectioned at 3, 6, and 9 mm from the apex with a low-speed saw under water-cooling. The slices were then examined under stereomicroscope for dentinal cracks. No cracks were found in the control group. Cracks were found in all treatment groups, predominantly in the 3 mm slices. There was no statistically significant difference in the number of cracks when comparing the different systems to each other at any section level. At 3 mm, however, five of the studied systems, namely K3XF (p = 0.004), Protaper Next (p = 0.001), Reciproc Blue (p<0.001), TF adaptive (p = 0.050), and 2Shape (p = 0.009) presented a significantly higher number of cracks than the control group. Within the limitations of this study, instrumented canals presented dentinal cracks, while uninstrumented ones presented no cracks after sectioning. There seems to be no significant difference among the tested systems regarding crack formation in the instrumented root canal wall. Crack formation occurred irrespective of the motion of the rotary system (rotational or reciprocation). Further studies are needed to clarify the factors that contribute to crack formation in the case of each individual rotary system.
