“…In the apical third of the canals, instrumentation with Mtwo resulted in significantly less smear layer formation compared to Twisted and ProTaper instruments (p<0.001) [Table/ Fig-2,6]. This result is consistent with previous reports that showed Mtwo to be superior in cleaning efficacy compared to ProTaper files [9,10,16].…”

“…In the present study a significant reduction in Enterococcus faecalis was observed after instrumentation of the root canal systems of deciduous molars using the WaveOne system, in agreement with others authors who observed similar canal cleaning capacity when different rotary and reciprocating systems were compared (WaveOne, Reciproc and MTwo) [19]. The WaveOne and Reciproc system exhibited similar efficacy for cleaning root canals in a previous study [20].…”

Objective: To assess root canal morphological results and cleaning capacity in deciduous teeth instrumented with a reciprocating system. Material and Methods: 15 deciduous molars and a total of 24 canals were selected for the study. Nine teeth (13 canals) were selected at random for microbiological analysis and 6 teeth (11 canals) were used for tomographic analysis of morphology. The roots used for the microbiological assessment were contaminated with standard strains of Enterococcus faecalis. All roots were instrumented using the WaveOne System with a Small (21:06) 21 mm file and an X-Smart plus motor. Tomography was conducted with an I-CAT machine before and after instrumentation with the objective of analyzing the WaveOne System's shaping capacity. Statistics: Biostat 4.0 software was used to analyze results. The microbiological results (log10) and tomographic results (pixels) were analyzed using descriptive statistics and the Wilcoxon test. Results: There was a significant reduction in Enterococcus faecalis colony-forming units after instrumentation of the root canal systems of deciduous molars using the WaveOne system (p=0.0033) and significant enlargement of the root canal systems was observed after instrumentation (p=0.047), while morphology was maintained. Conclusion: The WaveOne System, using the Small file was effective for disinfection of the root canal systems of deciduous molars.

“…For standardisation purpose, working lengths were established at À1 mm from the foramen in all samples; preparation and irrigation protocols were identical for both groups. It could be concluded that metallurgical properties and files design were more decisive than the number of instruments used and their kinematics on the cutting efficiency, debris production and thus the cleaning abilities of the files (12)(13)(14)(15). When comparing instruments in reciprocating motion of first generation WaveOne â and Reciproc â , similar effectiveness regarding the cleanliness of the apical third were found (9,10).…”

The aim was to evaluate debris and smear layer at 1, 3 and 5 mm from the foramen of single-file systems WaveOne Gold â and Reciproc Blue â . Thirty single-rooted teeth were prepared using one of the following NiTi instruments WaveOne Gold â and Reciproc Blue â . Root canals were observed under a scanning electron microscope. The presence of debris and smear layer at the apical third of root canals was evaluated. Data were analysed by Friedman and Wilcoxon tests. WaveOne Gold â produced significantly less debris and smear layer compared to Reciproc Blue â . However, the mean amount of debris was significantly different within distances for WaveOne Gold â , while no difference were observed for Reciproc Blue. The mean amount of smear layer was not significantly different within distances with WaveOne Gold â and Reciproc Blue â . Both systems showed debris and smear layer in the apical third; nevertheless, WaveOne Gold â showed better results.
