“…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.

“…In this study, the ProTaper F2 was used with a rotary motion, in accordance with the manufacturer's instructions and its design. Other studies, on the other hand, have employed clockwise and counterclockwise movement or a reciprocating movement 9,29) . Reciproc and WaveOne nickel-titanium files are designed to allow complete preparation and cleaning of root canals with only one instrument.…”

“…Therefore, recent studies have proposed protocols that recommend the use of a single file for root canal preparation 13,29) . Although the recent focus has been on the use of simplified techniques using only one file, no consensus has been reached on the comparative cleaning efficiency of each type of instrument 8,9,29) . The purpose of the present study was to compare the apical cleaning capabilities of single files from 3 different rotary systems in the presence or absence of prior cervical preparation based on a histological analysis.…”

The goal of this study was to compare the apical cleaning capabilities of single files from 3 different rotary systems in the presence or absence of prior cervical preparation based on a histological analysis. A total of 84 human single-rooted mandibular permanent incisors were divided into 6 groups (14 canals each). Cleaning and shaping was performed under the following protocols: Group I, F2 ProTaper at working length; Group II, SX ProTaper and F2 ProTaper; Group III, size 25, .06 taper Mtwo at working length; Group IV, SX ProTaper and size 25, .06 taper Mtwo; Group V, size 25, .06 taper BR3 BioRace at working length; and Group VI, SX ProTaper and size 25, .06 taper BR3 BioRace. After cleaning and shaping, the root canals were evaluated by histological analysis. The percentage of remaining debris was evaluated using a cross-hatched grid superimposed over each image. Data were assessed using the Shapiro-Wilk and ANOVA tests. Statistically significant differences were observed between groups (p=0.0001) with respect to amount of remaining debris; use of SX in conjunction with F2 ProTaper yielded a significantly lower mean percentage of debris. It was concluded that cleaning ability improves when root canal preparation with F2 ProTaper is complemented by prior cervical enlargement.

“…This was shown to be as effective at cleaning around root canals as the full ProTaper system, 12 and to extrude similar amounts of apical debris. 13 As a result of this paper there has been a re-emergence of reciprocation and development of single file NiTi preparation systems. Reciproc (VDW) and Wave One (DentsPly) single file systems were launched in 2011.…”
