Aim To determine the effect of blue thermal treatment on Reciproc (VDW, Munich, Germany) endodontic instruments and the amount of apically extruded debris during retreatment procedures. Methodology Thirty extracted mandibular molar teeth having mesial roots with a degree of curvature less than 20° and having an initial apical size equivalent to a size 10 K‐file were selected. The mesial roots of the teeth were removed from the cementoenamel junction to obtain a 15‐mm root length. The mesiobuccal canals were prepared to size F2 using the ProTaper Universal system (Dentsply Sirona, Ballaigues, Switzerland), filled with gutta‐percha and 2Seal (VDW) using the lateral compaction technique and then randomly divided into two groups (n = 15). The root fillings were removed with one of the following instruments using a crown‐down preparation technique: M‐Wire Reciproc or Reciproc Blue (both VDW). Apically extruded debris was collected in pre‐weighed Eppendorf tubes. The Eppendorf tubes were then stored in an incubator at 70 °C for five days to evaporate the distilled water. The data were analysed using the Mann–Whitney U test (P = 0.05). Results Reciproc Blue (1.42 ± 0.4491 mg) extruded significantly less debris apically than M‐Wire Reciproc (2.56 ± 1.0232 mg) (P < 0.05). Conclusions Blue thermal treatment of Reciproc instruments was associated with less debris extrusion during retreatment procedures.

SUMMARY Aim:We evaluated the effects of 5% NaOCl solution, 17% EDTA solution, and RC-Prep on the amount of apically extruded debris and the incidence of dentinal cracks during canal preparation using the ProTaper Next and Reciproc systems. Materials and Methods: In total, 255 human mandibular incisors were divided into eight groups (n=30 each) and a control group (n=15). Teeth in groups 1 (NaOCl), 2 (EDTA), 3 (RC-Prep), and 4 (EDTA+RC-Prep) were prepared using the ProTaper Next system, and those in groups 5 (NaOCl), 6 (EDTA), 7 (RC-Prep), and 8 (EDTA+RC-Prep) were prepared using the Reciproc system. Apical extrusion and crack formation were each examined in 15 teeth from each group. Extruded debris was collected in pre-weighed Eppendorf tubes. In the crack detection study, teeth were sectioned horizontally at 3, 6, and 9 mm from the apex. The slices were then viewed through a stereomicroscope at ×25 magnification.

“…This can be associated with undesirable consequences such as induction of inflammation, postoperative pain and delayed periapical healing (Kirchhoff et al ). Several studies reported that all techniques used to prepare a root canal and remove root canal filling material are associated with apically extruded debris (Topçuoğlu et al , Borges et al , Karataş et al , Koçak et al ). When the retreatment procedure is performed for a tooth with apical root resoption, the amount of apically extruded debris could be greater than that of a tooth without apical resoption.…”

Aim To compare the weight of apically extruded debris produced during the removal of root canal filling material using various files in extracted teeth with simulated apical root resorption. Methodology The root canals of one hundred and twenty extracted mandibular premolar teeth were prepared with Revo‐S files and filled using a cold lateral compaction technique with gutta‐percha and a resin‐based sealer (AdSeal; Meta‐Biomed, Cheongwon, Korea). Sixty teeth were randomly assigned to four control groups (hand file, ProTaper Universal retreatment file, D‐RaCe retreatment file, and Reciproc file) for the removal of root canal filling material. The apical portion of the remaining 60 teeth was modified to simulate apical root resoption, and the teeth were then randomly divided into 4 experimental groups (using the same techniques as in the control groups) for the removal of root canal filling material. Apically extruded debris was collected into pre‐weighed Eppendorf tubes and then dried. The mean weight of the apically extruded debris was assessed with an analytical balance to an accuracy of 10−4 g. Data were analysed using two‐way analysis of variance and a Tukey’s post hoc test. Results In the simulated apical root resorption groups, all file systems were associated with significantly more debris extrusion compared to the groups without simulated resorption (P < 0.05). The amount of apically extruded debris was greatest in the hand file groups compared with the other groups (P < 0.05). In the groups with simulated apical root resorption, the Reciproc system was associated with the least weight of apically extruded debris (P < 0.05), whereas there was no significant difference between the ProTaper Universal retreatment and D‐RaCe files (P > 0.05). In the groups without simulated apical root resorption, there was no significant difference between Reciproc, ProTaper Universal retreatment and D‐RaCe retreatment files (P> 0.05). The time required to remove the root canal filling material was as follows: hand file > ProTaper Universal retreatment = D‐RaCe retreatment > Reciproc (P < 0.05). Conclusions The weight of apically extruded debris was significantly greater in teeth with simulated apical root resorption than in those teeth without simulated apical root resorption. Hand files were associated with significantly more apically extruded debris in all groups during removal of root canal filling material.
