“…Variability has been observed between different rotary systems in terms of debris extrusion (9). This is thought to be caused by differences in cross-section and cutting blade design of a particular system as well as taper, tip, configuration, concepts of use, flexibility, alloy, number of files, kinematics, and cutting efficacy (10).…”

“…However, this fact does not represent a consensus in the recent specific literature. In a recent study, reciprocating single-file systems extruded fewer bacteria apically than a conventional multi-file rotary system (22). Moreover, other studies showed no differences between rotary and reciprocating movements regarding debris extrusion (23,24).…”

The aim of the present study was to evaluate and compare postoperative pain after foraminal instrumentation using 5.25% sodium hypochlorite (NaOCl) or 2% chlorhexidine (CHX) gel irrigation protocol in nonvital single-rooted teeth after reciprocating instrumentation. Sixty-two volunteers presenting a single root canal diagnosed with asymptomatic necrosis and apical periodontitis were randomized into 2 experimental groups regarding the irrigation protocol (ie, 5.25% NaOCl and 2% CHX gel groups). Endodontic treatment was performed in a single session under reciprocating instrumentation with foraminal instrumentation. Volunteers were instructed to record pain intensity. Scores from 1 to 4 were attributed to each kind of pain after 24, 48, and 72 h. Kolmogorov-Smirnov and Student´s t tests were used to determine significant differences at p<0.05. On average, the percentage of patients that had no or mild pain after 24, 48 or 72 h was 77.4%, 88.7% and 95.1%, respectively. No statistically significant age difference was found between the groups (p>0.05, Student´s t test). Postoperative pain showed no statistically significant difference at any observation period when using 5.25% NaOCl or 2% CHX gel (p>0.05). Moreover, no significant difference was observed in the mean number of analgesic tablets used between the groups (p>0.05). In conclusion, the use of 5.25% NaOCl or 2% CHX gel resulted in the same postoperative pain. Therefore, it can be inferred that irrigant choice has no relation with short-term follow up regarding postoperative pain.

“…This can be explained by differences in terms of kinematic and number of file in systems. It has indicated that single-file reciprocating instruments with Gold wire metallurgy caused less bacterial extrusion (30) and debris than conventional multifile rotary systems. The results of the present study may be explained with this observation.…”

Objective: To evaluate the bacterial extrusion during instrumentation with different nickel titanium (NiTi) engine-driven instruments. Methods: Ninety extracted single-canal human mandibular incisor teeth were inoculated with Enterococcus faecalis to obtain biofilm formation and were randomly divided to 6 groups (n=15). One group served as the control and was not instrumented; the other groups were prepared with ProTaper Gold (PTG; Dentsply Maillefer, Ballaigues, Switzerland), WaveOne Gold (WOG; Dentsply Maillefer), Twisted File Adaptive (TFA; SybronEndo, Orange, CA, USA), One Shape New Generation (OSNG; MicroMega, Besancon, France), and K3XF (SybronEndo) instruments. Bacteria extruded beyond the apical foramen were quantified in colony-forming units per milliliter. The number of colony-forming units in the remaining biofilm was determined for each sample. Data were analyzed using the one-way analysis of variance (ANOVA) and Tukey post-hoc tests. Results: All NiTi instruments resulted in different quantities of bacterial extrusion. The TFA group caused most bacterial extrusion (p<0.05). The PTG and WOG groups caused less bacterial extrusion than the OSNG and K3XF groups (p<0.05), but there was no statistically significant difference between the PTG and WOG groups (p>0.05). Conclusion: PTG and WOG are preferable system in terms of successful endodontic treatments. The amount of bacterial extrusion is associated with the metallurgy and design of the instrument used.

Apical extrusion of bacteria when using reciprocating single‐file and rotary multifile instrumentation systems

Abstract: All instrumentation systems extruded bacteria beyond the foramen. However, both reciprocating single-file systems extruded fewer bacteria apically than the conventional multifile rotary system.
