“…WaveOne Gold (WOG; Dentsply Sirona Endodontics, Tulsa, OK, USA), a heat-treated centric reciprocating motion file system, is a single use file, offering the simplicity of a one-file system with two cutting edges that has been reported to improve its shaping efficiency and fracture resistance (Adiguzel et al, 2017;Garcia et al, 2019). The XP-endo Shaper (XPS; FKG, La Chaux-de-Fonds, Switzerland), an eccentric rotary motion one-file system produced from NiTi MaxWire alloy, is reported to provide extreme flexibility and the ability to contract and expand allowing the file to extend into non-round, unreachable canal surfaces (Azim et al, 2017;Keskin et al, 2018).…”

“…Hence, the aim of this study was to compare the shaping ability of three recognized mechanical root canal systems with different kinematics in preparing oval-shaped distal canals of extracted mandibular molars, utilizing micro-CT imaging. Given the different designs, alloys, movements, and quantity of instruments of the systems (Azim et al, 2017;De-Deus et al, 2019;Elnaghy & Elsaka, 2017;Garcia et al, 2019), the null hypothesis is that there are no differences in the shaping ability of the three instrumentation systems in preparing oval distal root canals of extracted mandibular molars.…”

Aim: To compare the shaping ability of a heat-treated centric reciprocating file system (WaveOne Gold), a heat-treated eccentric rotary multifile system (TRUShape 3D Conforming Files), and a heat-treated expandable one-file rotary system (XPendo Shaper) extending its activation time, in preparing oval-shaped root canals in extracted mandibular molars by means of microcomputed tomography (micro-CT) analysis.Methodology: Thirty moderately curved oval-shaped distal roots of mandibular molars were selected. The normality of canal length, curvature angle, volume, surface area, structure model index, and aspect ratio were confirmed. The samples were randomly divided into three groups (n = 10). Micro-CT scans were taken before and after canals were instrumented using WaveOne Gold (size 35, .06 taper), or TRUShape (size 30, .06v taper), both following the manufacturer's instructions, or XP-endo Shaper following a new protocol with extended activation time. The mechanical preparation time for each sample was recorded. Pre-and postoperative images were analysed for the percentage of unprepared canal areas and the percentage of removed dentine. Data were compared between groups using the statistical analyses one-way ANOVA and Tukey tests (p < .05). Results:The percentage of unprepared canal areas was significantly higher with WaveOne Gold (% 11.5 ± 4.0) and TRUShape (% 12.4 ± 5.8) compared with XP-endo Shaper (% 5.2 ± 2.6) (p < .05). XP-endo Shaper removed significantly more dentine (3.3 ± 1.5 mm 3 ) than WaveOne Gold (1.8 ± 0.8 mm 3 ) and TRUShape (1.9 ± 0.8 mm 3 ) (p < .05). No significant differences were seen for mechanical preparation time between WaveOne Gold (79 ± 31 s), TRUShape (104 ± 41 s) and XP-endo Shaper (71 ± 23 s) (p > .05). Conclusions:The comparison of three recognized root canal filing systems has shown that with similar preparation times, the XP-endo Shaper removed more dentine (mm 3 ) leaving less unprepared canal wall area (%) than WaveOne Gold and TRUShape when preparing oval-shaped root canals of extracted mandibular molars.

“…In present literature, torsional resistance is the most used test to evaluate the metallurgical features of the alloy in a static rotational resistance [14]. Nonetheless, this type of test do not take into account the multitude of stresses, since NiTi rotary instruments are used dynamically [15].…”

Torque Range, a New Parameter to Evaluate New and Used Instrument Safety

The aim of the present study is to evaluate operative torque, torque at failure and the difference between these two values—the “torque range”—of two different NiTi files. We also sought to evaluate and compare these parameters for new and used files. Forty S-One 20.06 and forty M-Two 20.06 were tested, divided in four equal groups (n = 10) for each brand. Ten instruments from each brand performed three root canal treatments each on standardized extracted single-rooted teeth. Afterwards, each group was subjected to the following two tests: operative torque and torsional resistance. Mean values for all the tested groups were calculated. The results for new instruments showed that S-One developed significantly higher operative torque, but higher torsional resistance. The results for used instruments showed that the S-One 20.06 developed less operative torque and higher mean torsional resistance value compared to the M-Two. Moreover, the percentage reduction of both values was significantly higher for M-Two. The results of the present study showed a safer torsional behavior of the S-One. These results could be related to the heat treatment and the manufacturing process.

“…This reduces taper-lock and the screw-effect, improves safety, increases cutting efficiency, and provides more chip space to auger debris coronally. 67,68,80,115 WaveOne Gold is manufactured from Gold-Wire, a new super-metal that is said to render this system 80% more flexible, 50% more resistant to cyclic fatigue, and 23% more efficient than its predecessor, WaveOne (Dentsply Sirona), manufactured from M-Wire. 113,116 WaveOne Gold cuts in a CCW direction in reciprocating angle of 150° with a 30° CW disengaging angle at 300 rpm.…”

“…While evaluating structural and torsional properties of WaveOne and WaveOne Gold files, Paula Ribeiro et al 115 showed that WaveOne files exhibit higher torsional resistance than WaveOne Gold, probably due to geometric and metallurgic differences. While WaveOne Gold has higher angular deflection values due to the superior flexibility of Gold wire properties.…”

It is well described that the presence of microbial flora in the pulp space of the tooth, and the inability of the immune system to remove these pathogens, are the major sources of peri-apical and radicular inflam-mation.1 Eradication of these pathogens from the pulp and root canal space by means of cleaning, shaping, disinfecting and complete obturation is necessary to safeguard the health of the periodontal tissues from endodontic infection and subsequent breakdown.2,3 The basic objectives of cleaning and shaping of root canals include: (1) removal of all infected soft and hard tissues; (2) creating space for delivery of disinfectants and medicaments to the apical part of the canal; (3) facilitating three dimensional obturation and (4) preservation of radicular structures.4 Even modern endodontic file systems leave untouched areas on the root canal walls after preparation and show compaction of hard tissue debris.5 This debris consists of pulp tissue remnants, bacteria and dentine chips of which most is found in the apical part of the prepared root canal system.6 Aiming for a centred preparation that corresponds to the original canal anatomy accompanied by the lowest amount of canal transportation, especially in middle and apical parts of curved canals, will result in the most favourable post instrumented canal shape. The four optimal canal shaping objectives are: (1) to have a tapered funnel from orifice to apex, (2) maintenance of original anatomical canal pathway, (3) apical foramen position should remain constant and (4) leaving the apical opening as small as possible.2,7
