“…The disparity between the previously reported results and the present data may be due to the differences in canal morphology of the selected specimens. Nevertheless, in a study on biofilm removal by XP-F, PUI and conventional needle irrigation, the investigators found that XP-F was the most effective irrigation agitation technique to remove biofilms in infected tooth models (Bao et al 2017).…”

Aim To evaluate the effect of instrumentation using Reciproc Blue (RB; VDW, Munich, Germany) and XP‐endo Shaper (XP‐S; FKG Dentaire, La Chaux‐deFonds, Switzerland) systems on the area of untouched canal wall (AUCW), accumulated hard‐tissue debris (AHTD) and the efficacy of three irrigation protocols on percentage reductions (red%) of AHTD within C‐shaped canals of mandibular molars. Methodology Seventy mandibular molars with C‐shaped canals were scanned, matched and assigned to two shaping groups (n = 35): RB and XP‐S. Following instrumentation, specimens were triple‐matched with respect to the amount of remaining debris and assigned to three irrigation subgroups (n = 10): syringe‐and‐needle irrigation (SNI), XP‐endo Finisher (XP‐F; FKG Dentaire) and passive ultrasonic irrigation (PUI). The AUCW% and AHTD% after instrumentation and the red% of AHTD after irrigation were calculated from micro‐computed tomography. Data were analysed using comparisons for two groups (RB vs. XP‐S) or multiple subgroups followed by pairwise comparison procedures (SNI vs. XP‐F vs. PUI) at α = 0.05. Results For RB and XP‐S, 33.04% and 30.45%, respectively, of the canal wall remained untouched (P > 0.05). For both groups, the apical third had larger AUCW% than the coronal third (P < 0.05). Instrumentation with RB left more debris (2.8%) than XP‐S (1.1%) (P < 0.05). The PUI and XP‐F subgroups had higher mean red% of AHTD than the SNI subgroup; the difference was significant for RB (P < 0.05) but not for XP‐S. Conclusions Both RB and XP‐S systems were associated with similar AUCW after instrumenting C‐shaped canals. RB left significantly greater levels of AHTD compared with XP‐S. PUI and XP‐F irrigation removed more debris than SNI when using the RB system.

“…To date, few studies have evaluated the performance of the XP-endo Finisher instruments. Their ability to remove hard-tissue debris (Elnaghy et al 2017, Leoni et al 2017, bacteria (Alves et al 2016b, Azim et al 2016, Bao et al 2017) and calcium hydroxide paste (Uygun et al 2016, Wigler et al 2017, Keskin et al 2017) has been demonstrated. The ability of this instrument to remove filling material during root canal retreatment was reported to be 69% mean reduction in volume (Alves et al 2016a), which was similar to the results observed in the present study.…”

“…According to the manufacturer, when the instrument is placed inside the canal in rotation mode, the A-phase shape allows the file to access and clean areas that other instruments might not be able to reach, without damaging dentine or altering the original canal shape. Although this new concept looks promising, only a few reports have analysed its performance (Alves et al 2016a,b, Azim et al 2016, Uygun et al 2016, Bao et al 2017, Elnaghy et al 2017, Keskin et al 2017, Leoni et al 2017, Wigler et al 2017.…”

Silva EJNL, Belladonna FG, Zuolo AS, Rodrigues E, Ehrhardt IC, Souza EM, De-Deus G. Effectiveness of XP-endo Finisher and XP-endo Finisher R in removing root filling remnants: a micro-CT study. International Endodontic Journal, 51, 86-91, 2018. Aim To evaluate the efficacy of filling material removal from oval-shaped canals after the use of supplementary files (XP-endo Finisher and XP-endo Finisher R) through microcomputed tomographic (micro-CT) analysis. Methodology The root canals of twenty maxillary single-rooted teeth were prepared with Reciproc R25 files and filled with gutta-percha and AH Plus sealer using the continuous wave of condensation technique. The root canals were then retreated using Reciproc R25 and R40 instruments. After this, the specimens were assigned to two groups according to the supplementary cleaning approach, using XP-endo Finisher and XP-endo Finisher R. The surface area and volume of removed filling material was assessed using micro-CT imaging before and after the use of the XP-endo instruments. Data were analysed statistically with a significance level of 5%. Results Removal of filling material at 66.8% and 59.4% in volume and 67.3% and 61.4% in surface area was seen for the XP-endo Finisher and the XPendo Finisher R files, respectively. The amount of filling material removed by both supplementary files was highly significant (P = 0.000). No significant difference in the percentage of removed filling material was detected for the XP-endo instruments (P = 0.636 for volume and P = 0.667 for surface area). Conclusions Both XP-endo files were equally effective in the removal of remaining filling material from straight oval-shaped canals. None of the instruments were able to remove all the residual filling material.
