“…Solvents have been traditionally used to facilitate removal of gutta-percha and sealers from the root canal during retreatment (Gutmann & Lovdahl 2011). Although the use of rotary instruments may make the use of solvents unnecessary for filling material removal, some authors have used them in association with rotary instruments (Kfir et al 2012, Keskin et al 2017, Rossi-Fedele & Ahmed 2017. No consensus exists concerning the benefits of using solvents.…”

Aim To evaluate the effectiveness of a solvent (eucalyptol) in improving filling material removal from canals connected by isthmuses, and the additional cleaning effect of a finishing instrument. Methodology The mesial canals from 32 mandibular molars (Vertucci's type II morphology) were instrumented and filled with the single‐cone technique using Reciproc R25 gutta‐percha points (VDW, Munich, Germany) combined with Sealer 26 (Dentsply, Petrópolis, RJ, Brazil). Each root was then subjected to retreatment using the Mtwo instrument system (VDW), with or without a solvent (n = 16 per group). The volume of filling material in the canals was assessed by micro‐computed tomographic (micro‐CT) scans taken before and after retreatment. Canals with remnants of filling material received a supplementary procedure with the XP‐endo Finisher R instrument (FKG Dentaire, La Chaux‐de‐Fonds, Switzerland), with or without eucalyptol, and another micro‐CT scan was taken. All retreatment procedures were performed inside a cabinet under a controlled temperature (37 °C). Filling material removal was evaluated in the 5‐mm apical canal system for the canal+isthmus space or the isthmus alone. Statistical analyses were performed to compare the removal of filling material with and without eucalyptol, and after a supplementary approach with XP‐endo Finisher R. The level of significance was set at 5% for all statistical tests (P < 0.05). Results The amount of filling material removed from the canal+isthmus with Mtwo instruments was 83.2% when no solvent was used and 83.8% using the solvent (P > 0.05). When the isthmus area was evaluated separately, most specimens were associated with a reduction in the filling material, with no significant difference between the groups with or without using a solvent (P > 0.05). The supplementary step with XP‐endo Finisher R significantly improved removal of filling material from both canal and isthmus area (P < 0.05), regardless of the use of a solvent (P > 0.05). Conclusion The use of eucalyptol did not improve filling material removal from Vertucci's type II molar mesial canals and isthmuses. XP‐endo Finisher R significantly enhanced removal of filling material from the canals and isthmuses.

“…Orange oil is an essential oil recommended as a biologically compatible alternative to chloroform to soften gutta-percha. 29,30 In a study conducted by Keskin et al 31 , the effect of solvents on apically extruded debris was evaluated and it was detemined that the use of solvents reduced significantly the amount of apically extruded debris compared to the control group (without solvents). In this study, it was also observed that chloroform caused significantly more debris extrusion than orange oil and terabentine oil.…”

This study aimed to compare the effect of various nickel-titanium rotary retreatment systems on intenstiy of postoperative pain after non-surgical endodontic retreatment. Materials and methods: One hundred and eighty patients requiring endodontic retreatment were included in the study. The patients were randomly assigned into three groups of 60 patients, according to the method used to remove old canal filling material. In group 1, canal filling material was removed using ProTaper Universal retreatment (PTUR) instruments. In group 2, the canal filling material was removed with D-Race retreatment instruments. In group 3, Mtwo instruments were used to remove canal filling material. Teeth were then medicated with calcium hydroxide and sealed using temporary filling material. The presence of postoperative pain was assessed after 6, 12, 24, 36 and 72 h, 7 days. Results: Among the three groups, the highest postoperative pain scores were recorded 6 hours after the procedure; the postoperative pain scores decreased over time in all time intervals. In 6 hours, Mtwo group exhibited higher pain score than those of D-RaCe group (P < .05), but there was no difference in the pain scores between D-RaCe and PTUR group; Mtwo and PTUR (P >.05). Conclusions: Retreatment files tested in this study caused similar postoperative pain levels after non-surgical endodontic retreatment, except at 6 hours.

“…It has been determined that initial canal preparation during root canal treatment may produce apically extruded debris during instrumentation (Bürklein & Schäfer , De‐Deus et al , Silva et al ). However, there are only a limited number of studies evaluating the weight of apically extruded debris produced during the removal of root canal filling material (Silva et al , Topçuoğlu et al , Keskin et al ). This study assessed the weight of apically extruded debris produced during the removal of root canal filling material using various techniques in teeth with simulated apical root 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.
