“…12,22,23 To study the performance of the instruments examined through the whole canal length, the analysis of three different canal levels-apical, middle, and coronal levels, represented by 3 mm, 5 mm, and 7 mm from the apex, respectively, was performed. 21,24,25 The results of this study showed that at the middle and the coronal levels, there was no significant difference between the four groups in canal centering ratio or the amount of canal transportation. However, at the apical level, WaveOne Gold files showed the best centering ratio and the least amount of canal transportation.…”

Objectives To evaluate the shaping ability of four different single-file systems using micro-computed tomography (micro-CT). Materials and Methods Eighty mesiobuccal and mesiolingual canals of permanent mandibular molars were randomly assigned to four groups according to the file used; WaveOne Gold, RECIPROC Blue, HyFlex EDM, and One Shape (n = 20). The samples were scanned using micro-CT for the preinstrumentation record; then the canals were instrumented and scanned for the postinstrumentation records. Statistical Analysis The data were then analyzed statistically using one-way analysis of variance (ANOVA) with the level of significance set at α = 0.05. Results The results of canal centering ratio and canal transportation showed that no significant difference was found among the four file groups at the middle and the coronal levels. However, a significant difference was found at the apical level (p < 0.05), where WaveOne Gold showed the best centering ratio and the least amount of canal transportation. The change in the canal volume was significant at the coronal level (p < 0.05), whereas the change in the canal volume was higher for the HyFlex EDM group than the other groups. No significant difference was found between the other groups at the apical level, middle level, or in the total percentage of canal volume. Conclusion WaveOne Gold produced a more centralized canal preparation with a lesser amount of transportation at the apical level. HyFlex EDM showed the highest canal volumetric change at the coronal level. The interim design of the endodontic files has a high impact on the behavior of the file inside the root canal.

“…32 Previous studies showed similar performance for WaveOne Gold. 25,33,34 It was found that all the four groups showed a centering ratio more than one at the apical level indicating the tendency of all the instruments used to prepare more of the outer surface of the canal curvature rather than the inner surface. 17…”

“…The presence of curved canals can be challenging during root canal preparation and are not always detected clearly on periapical radiographs, which can cause undesirable shaping errors (Vallabhaneni et al 2017, Yammine et al 2017. In this study, singlerooted mandibular premolars with root curvatures ranging from 20°to 30°were used.…”

Aim To evaluate the influence of larger apical canal enlargement in curved canals using reciprocating systems subjected to various heat treatments. Methodology Ninety mandibular premolars with root curvatures ranging from 20° to 30° were selected and scanned by microcomputed tomography (micro‐CT) before and after root canal preparation with reciprocating systems (n = 30): Reciproc Blue (RB size 25, .08 taper and size 40, .06 taper; VDW, Munich, Germany), WaveOne Gold (WOG size 25, .07 taper and size 35, .06 taper; Dentsply Sirona, Ballaigues, Switzerland) and ProDesign R (PDR size 25, .06 taper and size 35, .05 taper; Easy Dental Equipment, Belo Horizonte, Brazil). Canal transportation, untouched areas, and apical and total root canal volumes were measured. Statistical analysis was performed with the nonparametric Kruskal–Wallis and Dunn's tests and a significance level set at 5%. Results The between‐group comparison revealed no significant difference in untouched areas, canal transportation, and apical root canal volume among the groups (P > 0.05). However, WOG size 35, .06 taper was associated with a significant increase in the percentage of total canal volume in comparison to the PDR size 35, .05 taper (P < 0.05). The within‐group comparison revealed a significant decrease in untouched areas, increase in apical and total root canal volume for all groups when using a larger instrument (P < 0.05). There was no significant difference in transportation among the groups and when a larger apical preparation was created (P > 0.05). Conclusions Larger apical enlargement of curved canals was associated with a decrease in untouched areas, an increase in root canal volume and maintenance of canal trajectory. In addition, all systems were safe and provided similar root canal shapes.
