“…The WOG Glider files are manufactured using a proprietary novel heat-treatment technology. Contrary to the M-Wire technology that is a pre-production heat treatment, the WOG Gilder files are produced by heating and then slowly cooling the alloy after the production of the files (Elsaka et al 2016). Elsaka et al (2016) examined the bending and torsional resistances of WOG, Reciproc (RPC, VDW) and Twisted File Adaptive (SybronEndo, Orange, CA, USA) and reported the reason for the lower bending resistance of WOG files when compared to the other systems might be their two-phased transformation behaviour and high Af value.…”

As a consequence, the lower bending resistance of WOG Glider files made of this proprietary thermomechanically treated alloy when compared to R-Pilot files made of M-Wire alloy might be mainly attributed to the metallurgical properties of these files.…”

“…The greater ductility of heat‐treated instruments could be helpful during their clinical use because it is expected that noticeable alterations in the cutting spirals (plastic deformation) might appear before instrument fracture (Elsaka et al . , Alcalde et al . , Silva et al .…”

Aim To evaluate the influence of controlled memory (CM) thermal treatment on the torsional resistance and surface roughness of nickel‐titanium instruments with identical geometric and dimensional characteristics. The influence of environmental temperature on torsional resistance was also evaluated. Methodology A sample of 25 conventional NiTi alloy and 25 CM thermal‐treated NiTi instruments, with an identical geometric design and a nominal size of 0.25 mm at D0 and a nominal taper of .06 mm mm−1 were selected. The torsional strength and the angle of rotation of the instruments were tested following ISO 3630‐1 at two temperatures: 21 and 35 °C. The fracture surfaces of all tested instruments were verified with a scanning electron microscope. The surface roughness of the blades of conventional NiTi alloy and CM wire files was evaluated by using a New View 7100 Profilometer. Statistical analysis was performed using Student's t‐test and paired t‐test to analyse the torsional resistance and surface roughness at a significance level of P < 0.05. Results The torsional strength of thermally‐treated instruments was significantly lower than nontreated instruments (P < 0.05). However, thermally‐treated instruments had significantly greater angular rotation to fracture than nontreated instruments (P < 0.05). Temperature did not influence the torsional strength (P > 0.05) and the angular rotation (P > 0.05) of the instruments. Regarding the roughness measurements, groove depth was lower at the surface of thermally‐treated instruments when compared to nontreated instruments (P < 0.05). Conclusion Thermal treatment influenced the torsional resistance and surface roughness of NiTi instruments with identical geometric and dimensional characteristics. Temperature did not affect torsional behaviour.

“…M-Wire, an alloy created by applying a heat treatment to conventional NiTi, is presented in Reciproc® (VDW, Munich, Germany) and Wave One® (Dentsply Maillefer, Ballaigues, Switzerland) ( 14 , 15 ). Gold-Wire is another alloy that has recently appeared, enhancing the properties of ProTaper Universal® (Dentsply Maillefer, Ballaigues, Switzerland) and Wave One® (Dentsply Maillefer, Ballaigues, Switzerland), to create ProTaper Gold® (Dentsply Maillefer, Ballaigues, Switzerland) and Wave One Gold® (Dentsply Maillefer, Ballaigues, Switzerland) ( 16 , 17 ), with a new thermal surface treatment ( 18 ). CM-Wire is an alloy that gives Hyflex CM® (Coltene, Altstätten, Switzerland), Hyflex EDM® (Coltene, Altstätten, Switzerland) and Neoniti® (Neolix, Chatres-La-Foret, France) instruments controlled memory, which is very useful when treating root canals with severe curvatures ( 19 - 21 ), manufactured with wire cut electrical discharge machining (EDM) process ( 22 ).…”

ObjectiveThe aim of this study was to compare the cutting are, root canal anatomy preservation and non-instrumented areas of F360®, F6-SkyTaper®, Hyflex-EDM®, iRACE®, Neoniti®, O.Shape®, P.Next®, Reciproc®, Revo-S® and Wave-One-Gold® size 25 files.Materials and Methods300 teeth with a single straight root and a circular or elliptical root canal were divided into 10 groups (1-F360®, 2- F6-SkyTaper®, 3-Hyflex-EDM®, 4-iRACE®, 5-Neoniti®, 6-O.Shape®, 7-P.Next®, 8-Reciproc®, 9-Revo-S® and 10-Wave-One-Gold®) cut into 3 cross sections using an ultrafine cutting disc. They were photographed under a stereo microscope and preinstrumentation analyses were made before rebuilding the teeth with# 10 K- File and epoxy glue. A glide path was created with #10 and #15 K files and each group was instrumented using rotary or reciprocating systems. Cutting areas, root canal anatomy preservation and non-instrumented areas were analyzed using the AutoCAD 2015 Levene's test, the Welch´s test, and the Games-Howell´s test. The Pearson’s chi-squared test was used for statistical analysis.ResultsLevene's test showed no equality of variances (P<0.05), therefore Welch´s and Games-Howell's tests were applied to cutting areas, showing significant differences in all thirds and overall (P<0.05). No differences in root canal anatomy preservation were observed (P>0.05). In non-instrumented areas, significant differences were found (P<0.05) in middle third being better in Reciproc®, Neoniti® and WaveOneGold®, and in apical thirds being higher P.Next®, Reciproc®, HyflexEDM®, Neoniti® and WaveOneGold®.ConclusionsIn cutting area, P.Next® and Reciproc® were superior in coronal third, Neoniti® and Hyflex EDM® medially and apically and Neoniti® and Reciproc® overall. Regarding the root canal anatomy preservation, all systems were similar. For non-instrumented areas, all systems achieved similar results coronally, but Reciproc®, Neoniti® and Wave One Gold® were superior in middle third and P.Next®, Reciproc®, Hyflex EDM®, Neoniti® and Wave One Gold® were superior in apically.
