“…It is also worth emphasizing that the results of the present study differed from those presented by Topçuoglu et al., in which the instrument of the reciprocating system (RC) promoted a higher apical debris extrusion value than those of the PTN system instruments . However, in the previously‐cited research, instruments of smaller diameter were used, demonstrating that instrument diameters could be a preponderant factor with respect to debris extrusion.…”

Aim: The aim of the present study was to evaluate the effect of large instrument use on the shaping ability and apical debris extrusion of rotary and reciprocating systems in oval-shaped root canals.Methods: Forty-five mandibular premolars, with an 18-mm long, oval-shaped single canal, and apical diameter ranging from 300 to 350 μm, were separated into three groups (n=15), according to the system used: ProTaper Universal group, F5 (0.50/0.05);ProTaper Next (PTN group), X5 (0.50/0.06); and Reciproc (RC group), R50 (0.50/0.05). Cone-beam computed tomography was performed before and after preparation toanalyze apical transportation (AT), centering ability (CA), and change in root canal diameter (CRCD). For evaluating apical debris extrusion, the roots were coupled to preweighed glass receptacles to collect the extruded debris during preparation.Results: All systems promoted AT and apical debris extrusion; the latter was higher for the PTN group (P<.05). No system presented perfect CA. The RC group demonstrated the largest CRCD (P<.05). Conclusions:As consequences of their use, the large instruments promoted undesirable AT and debris extrusion, irrespective of the system used to perform root canal preparation. Moreover, no system was able to remain perfectly centralized within the root canal. K E Y W O R D Sendodontic, large instrument, mandibular premolar, root canal preparation, tomography

“…Overall, experimental groups in comparative studies have been created by selecting randomized either single‐ or multi‐rooted teeth with limited sample size (Topçuoğlu et al 2016, Silva et al 2017, Pedullà et al 2019). In practice, this means a very poor standardization and the inability to ensure experimental comparability as it may yield experimental groups with large variations in the baseline of the substrate (Smith & Steiman 1994, També et al 2014).…”

Aim To introduce a new method to select anatomically matched teeth using micro‐computed tomographic (micro‐CT) technology. Methodology Single‐rooted mandibular incisors with a single root canal (n = 60) were selected and distributed into three experimental groups according to the method used for matching 10 pairs of teeth in each group. In group 1, the pairs of mandibular incisors were randomly selected from a pool of teeth. In group 2, teeth were paired based on the measurement of canal width 5 mm from the root apex using radiographs taken from buccolingual and mesiodistal directions. In group 3, teeth were scanned (pixel size of 14.25 μm) and pair‐matched based on the anatomical aspects of the root canal, named aspect ratio (AR), volume and three‐dimensional canal geometry. After allocating the specimens into groups 1 and 2, the teeth were scanned and the canal morphology evaluated as in group 3. A bivariate Pearson’s regression analysis was performed correlating the individual AR values of each pair, and the correlation coefficient was used to estimate the strength of the pair‐matching process. One‐way anova post hoc Tukey’s tests were applied for pairwise comparisons at a significance level of 5%. Results The micro‐CT revealed that 100% of the samples had strong (80%) or very strong (20%) correlations with respect to AR values. Analysis of the radiographic method revealed strong correlation in two pairs (20%), but most of the samples had weak (30%) or negligible (30%) correlation coefficients. The randomization method resulted in three pairs (30%) with very strong correlations, whilst 50% had weak or negligible rates. A significant difference in correlation coefficients was observed in the micro‐CT method compared to the other groups (P < 0.05), whilst no difference was detected between radiographic and randomized methods (P > 0.05). Eta‐squared (η2) calculations demonstrated a very high effect size in the micro‐CT group for selecting pairs (0.99) and lower effect sizes in the radiographic (0.67) and randomized (0.66) groups. Conclusions Use of Micro‐CT was able to provide better control of the confounding effect that anatomical variances in tooth morphology may have on the results in experiments with matched‐pair design.

Abstract: All instruments were associated with apical extrusion of debris. VB and PTN files were associated with less debris extrusion compared to the other systems.
