Background This simulated study of 30 severely curved L-shaped root canals aimed to compare preparation time, aberrations, width measurements, and fractured files of three nickel–titanium (Ni–Ti) files, namely, ProTaper, ProTaper Next (PTN), and WaveOne (WO). Methods Thirty simulated L-curved root canals of resin blocks were randomly divided into three groups. The canals were prepared to a tip size of 25 using ProTaper, PTN, and WO rotary file systems. Pre- and post-operative views for each sample were captured by a professional camera at a standardized distance and position. Blue India ink was injected into the pre-operative canals, and red India ink was injected into the post-operative canals to give a clear superimposition image. Five points were assessed through the halfway of the canal to the orifice (area between the beginning of curvature and apical end point). Preparation time, aberrations, width measurements, and fractured files were recorded and analyzed. Results Mean preparation time was longest in ProTaper (4.89±0.68 minutes). PTN and WO were the fastest in preparing the canals (about 3 minutes). A statistically significant difference was found between WO and ProTaper & PTN and ProTaper (p=0.000), while the difference was non-significant (p > 0.05) between WO and PTN. Nine aberrations consisting of three zips, one ledge and one outer widening were related to ProTaper, while WO recorded a ledge and fractured file, but for PTN system, it verified an outer widening and ledge. Only one WO file fractured, with no deformation observed in the other instruments. No significance was recorded among the width measurements in the different levels. Conclusion ProTaper next achieved faster cutting than the ProTaper and WO file systems. PTN maintained the best apical termination position and produced the least canal aberration, followed by WO and ProTaper.

“…It is reported to be less prone to dentin removal during instrumentation [9], even in canals with high curvatures [10]. In addition, it enabled a faster canal preparation compared to other nickel-titanium (Ni-Ti) instrumentation systems, such as ProTaper Next [11].…”

“…Several studies on the effect of operator experience using mechanized systems concluded that, despite the good performance obtained by inexperienced operators, the associated learning curve should be highlighted; they considered it a crucial factor for establishing the minimum amount of work required for students to obtain the necessary competence for independent professional practice [16,[23][24][25][26]. Regarding the use of reciprocating systems, characterized by a simple and safer protocol [4,11], there are still few studies that evaluate the quality of the treatments performed by inexperienced operators, such as, undergraduate students, and the extension of its learning curve.…”

Rotary instrumentation has been proposed in undergraduate teaching. The aim of this study was to evaluate student’s performance, through the obturation quality and treatment time, in a sequential range of L-simulated root canals. A senior undergraduate dental student sequentially prepared randomly numbered canals from 1 to 40, with the WaveOne Gold glider and primary file, according to the manufacturer instructions. A gutta-percha cone matched with the finishing instrument and epoxy resin-based sealer (AH Plus) was selected for the obturation. Three independent observers evaluated the obturation quality according to both density and length. Active, total instrumentation and obturation times were also measured. Statistical analysis was obtained by Mann–Whitney and Kruskal–Wallis tests with a significance level of p < 0.05. The quality of the obturation was independent of the number of prepared canals with adequate length and density in 87.5% of the prepared canals. Both active and total instrumentation, as well as obturation times, reduced significantly as the number of the prepared canals by the student increased (p ˂ 0.05). The use of WaveOne Gold instrumentation and matched cone obturation by an inexperienced operator provided an adequate obturation quality in most of the curved simulated canals. The working time was significantly reduced through a short learning curve.

“…The shaping procedure of root canals has significant effect on success of endodontic treatment. [1][2][3] icroorganisms, dentin chips, pulp tissue or irrigation solution may be extruded into the periapical tissues during the biomechanical preparation. 4 .The apical extrusion phenomenon may cause unwanted postoperative complications such as pain, periapical inflammation, delay of periapical healing, and edema.…”

The aim of this study was to compare apically extruded debris caused by different pecking depth of Reciproc and HyFlex EDM systems. Materials and Methods: Seventy-two human mandibular premolar teeth were randomly divided into 4 experimental groups (n=18) based on the file type and pecking depths. In Group 1, a HyFlex EDM (Coltene-Whaledent, Allstetten, Switzerland) with 2 mm distance was used, in Group 2, HyFlex EDM with 4 mm distance was used. In Group 3, Reciproc (VDW, Munich, Germany) with 2 mm distance was used, and in Group 4, Reciproc with 4 mm distance was used. The apically extruded debris was collected in pre-weighed Eppendorf tubes. Three sequential weight measurements were recorded for each Eppendorf tubes, and the average values were noted. Debris amount was calculated by subtracting the weight of the empty tubes from the weight of the tubes containing the debris. The data were analyzed using one-way analysis of variance (ANOVA) and Tukey's post hoc tests. Results: There was statistically significant difference between Group 4 (Reciproc with 4mm distance) and all the other groups (p<0.05), while no statistically significant was found among the other groups (p>0.05). The preparation time was the statistically significantly different between groups (p=0,008) and preparation time was longer in Group 1 than in Group 2 (p=0,012) and Group 4 (0,017). Conclusions: Within the limitations of the present study, all groups led to a measurable apical extrusion of debris and reciprocal motion with increasing the pecking depth caused the most debris extrusion.
