“…In the present study, evaluation of the apical extrusion of debris produced by continuous rotary-file systems versus single-file reciprocating system demonstrated that all instruments created apical debris extrusion, in agreement with the previous studies. 1 5 10 29 31 32 33 Dincer at al reported that continuous rotary systems extruded more debris than reciprocating systems (dried extruded debris) at the WL. 31 In addition, Karataş et al specified that WOG system produced less debris than the continuous rotation systems such as the ProTaper Gold and ProTaper Universal systems.…”

Objectives This in vitro study aimed to compare the amount of mixed and dried debris extruded with three endodontic NiTi (nickel–titanium) systems at three levels beyond the major apical foramen. The null hypothesis is that there would be no differences between the different rotary systems in terms of apically extruded debris. Materials and Methods Forty-eight roots of human extracted molars with 20 to 40-degrees curvature were divided randomly into three groups (n = 16) instrumented with ProTaper Next, BT RaCe, and WaveOne Gold, respectively. Instrumentation was performed at the major foramen and over instrumented 0.5 mm, 1.0 mm and 1.5 mm beyond. Irrigation was performed with sodium hypochlorite. Apically extruded debris was collected. Results Comparison of mixed extruded debris (solution/debris)and dried debris according to group and level of instrumentation showed that WaveOne Gold at the foramen and ProTaper Next beyond the foramen (p < 0.0001) resulted in significantly less extruded debris than other files and within the four levels using repeated measures analysis of variance (p < 0.0001b). Conclusions All systems exhibit extruded debris during instrumentation but in different amounts.

“…Previous studies demonstrated that all canal preparation techniques are associated with wide-ranging variability in debris extrusion depending on the mechanical systems used. [ 12 13 14 15 ] This could be attributed to differences in the cross-section, cutting-edge design, taper, tip type, configuration, concept of use, flexibility, alloy type, number of files used, kinematics, or cutting efficacy. [ 16 ] The alterations in these properties may be the determinants responsible for higher pain scores of Group A and Group B when compared to Group C.…”

Aim:The aim of this study is to compare the incidence of postoperative pain using the ProTaper Next (PTN), WaveOne Gold (WOG), and Self-Adjusting File (SAF) systems.Materials and Methods:Two hundred and fourteen patients with irreversible pulpitis were selected for single-visit endodontics. The teeth were blindly assigned to three groups based on the instrumentation system used: Group A (PTN), Group B (WOG), and Group C (SAF). Participants were asked to note the incidence of the pre- and postoperative pain on a visual analog scale at different time intervals. Paired t-test and one-way ANOVA were used along with post hoc Tukey's test.Results:The greatest mean pain in Group A (PTN) and Group B (WOG) was found to be maximum in the first 24 h with a significant reduction in pain at the subsequent observation time points of 48 h, 72 h, and 7 days. Group C (SAF) showed minimum pain followed by Group B followed by Group A which showed comparatively higher pain scores even at the end of 7 days.Conclusions:In single-visit endodontics, SAF system may prove to be a better system compared with PTN and WOG as it produces minimal postoperative pain, thus improving the overall acceptance of endodontic treatment.

“…In the process of root canal preparation, irritants such as infected debris can be squeezed into the periapical tissue to induce acute inflammatory reaction. So far, all the instruments and techniques of root canal preparation are related to a certain degree of fragment extrusion [5,6]. Glide path preparation, establishment of apical patency and endodontic status are important factors that affect and reduce the incidence of the post-treatment pain [3,[7][8][9].…”

Background This randomized clinical trial aimed to compare the preparation time and severity of postoperative pain between HyFlex Electric Discharge Machine (EDM) glide path file (GPF) and PathFile. Methods Eighty patients whose molar teeth had at least one severely curved canal were treated by the same specialist. After access cavity preparation, the patients were randomly assigned to receive glide path enlargement with either HyFlex EDM GPF or PathFile. ProTaper Next X1 and X2 files were used to prepare the canals. The time of preparation was assessed and the severity of postoperative pain over the next 7 days was recorded. The preparation time and the postoperative pain scores were compared using the Linear Mixed Models (P ≤ 0.05). Results Glide path enlargement time was significantly shorter with HyFlex EDM GPF (27.828 ± 2.345 s) than with PathFile (48.942 ± 2.864 s) (P < 0.001). The highest postoperative pain score was recorded on the first day and the pain decreased over time in both groups. HyFlex EDM GPF group patients reported significantly less postoperative pain than PathFile group patients overall (P < 0.001). Conclusions Postoperative pain and glide path preparation time could be reduced by using HyFlex EDM GPF system. Trial registration PKUSSNCT, PKUSSNCT-17B12, Registered 24 October 2017.
