“…The comparison between groups displayed significant differences regarding changes in 3D parameters after preparation, and the hybrid GN system demonstrated a superior shaping ability compared to the reciprocating WO system. Previous findings revealed that the shaping ability of the hybrid GN instruments is not superior to rotary endodontic instruments [7]. However, no studies have compared the efficiency of these instruments to reciprocating systems.…”

“…The preservation of the original root canal configuration and lack of procedural errors, such as root canal transportation, and avoidance of instrument separation, is directly related to the higher success rates of endodontic treatment and survival of the endodontically treated teeth [20]. During the last decade, the µCT imaging has been the most widely used method to precisely quantify and qualify many 3D parameters of the root canals after cleaning and shaping procedures [7,12,21]. It has been shown that extracting natural teeth is superior to simulating root canals for testing the shaping abilities of endodontic instruments, as they represent more realistic clinical conditions [22,23].…”

“…It has been shown that reciprocating file systems resulted in a less centered, more invasive preparation and produced more root canal transportation in comparison to the conventional or thermal treatment NiTi alloy rotary files [15,21]. The previous report indicated that hybrid Genius instruments are comparable to BioRace and ProTaper NEXT rotary file systems regarding the degree of the root canal transportation [7]. However, no published data compares the impacts of root canal preparation with hybrid and reciprocating endodontic instruments; therefore, it was impossible to compare our results with previous findings.…”

“…The Genius instrument system was recently developed as a hybrid asymmetric reciprocation-rotary system (GN; Ultradent Products Inc., South Jordan, UT, USA) containing six endodontic instruments: the Orifice shaper and five shaping files. The main design features of the GN instruments are austenite NiTi alloy, S cross-sections, modified flutes and a non-cutting tip [7]. The manufacturer claims that GN instruments can be used in asymmetric reciprocating as well as continuous rotating movements [8].…”

“…There are a few published scientific articles about the shaping ability and cyclic fatigue resistance of WO instruments [9,15,16]. However, just one recently published study compared the GN instruments and rotary files, regarding the 3D changes in the root canals after instrumentation [7]. However, there is no data published about the effectiveness and performance of the hybrid GN instruments in comparison to reciprocating file systems.…”

The aim of this study was to investigate the shaping ability and cyclic fatigue resistance of Genius (GN) and WaveOne (WO) nickel-titanium (NiTi) instruments. Forty mesial root canals of mandibular molars were randomly divided into two groups, according to the instrument system used for root canal preparation (n = 20): GN and WO. Root canals were prepared to the full working length using the crown-down technique, with up to 40.04 instruments for GN group and 40.08 instruments for WO group. Specimens were scanned with a µCT before and after instrumentation. The changes in 3D parameters and degree of canal transportation were evaluated in the apical, middle and coronal thirds of root canals. Size 25, taper 0.04 (GN) and 0.08 (WO) instruments (n = 20) were used in simulated root canals until fracturing, and the number of cycles to failure (NCF) was recorded. The fractured files were investigated under a scanning electron microscope to characterize fractured surfaces. Data were analyzed using ANOVA post hoc Tuckey’s tests with the significance level set at 5%. The GN system was able to prepare the higher percentage of the canal surface with less canal transportation in all root canal thirds and displayed the higher resistance to cyclic fatigue in comparison to WO instruments (p < 0.05). However, the length of the fractured segments was not significantly different among the groups; meanwhile, SEM investigations revealed the typical topographic characteristics of fractured surfaces. Hybrid GN instruments demonstrated superior shaping ability and resistance to cyclic fatigue. However, both NiTi instrument systems prepared the root canals with no significant shaping errors, considerable changes in 3D parameters and no significant differences in the topographic appearances of the instrument surfaces after fractures.

To compare the shaping ability of Procodile and R6 Reziflow instruments used in reciprocating motion in severely curved root canals, assessed with micro‐computed tomography (μCT). Fourteen extracted human mandibular first molars were randomly assigned to two instrumentation techniques (n = 14 mesial root canals): Procodile or R6 Reziflow. For both groups, root canals were prepared to the working length up to a size 25, .06 taper. Molars were virtually divided into apical, middle and coronal thirds and μCT was used to scan all samples pre‐ and post‐root canal. Canal transportation, centring ability, volume, surface area and unprepared area were evaluated. Geometrical parameter changes were compared with preoperative values (one‐way analyses of variance and Tukey multiple comparison post‐hoc test) between groups and Student t‐test within groups (α = 0.05) Significantly less transportation was observed associated with the Procodile technique in the molar's coronal third compared to the R6 Reziflow technique (p < .05). No significant differences in root canal centring ability, volume, surface area and unprepared area were observed. Procodile showed a lower percentage increase of surface area compared to R6 Reziflow (p < .05). The Procodile and R6 Reziflow techniques applied to first molar root canal performed similarly except for the less transportation observed in the coronal third using Procodile.Research HighlightsMicroCT analysis of canal geometry before and after instrumentation revealed that Procodile and R6 Reziflow showed a similar shaping ability to shape curved root canals without substantially modifications of the original tooth anatomy.

Abstract: The shaping ability of the BR, PTN and GN NiTi file systems was equally effective. All instrumentation systems prepared curved root canal systems with no evidence of undesirable changes in 3D parameters or significant shaping errors.
