“…Consequently, proper removal of both the gutta-percha and sealer is essential for successful root canal retreatment (2). Several techniques have been developed for the effective removal of gutta-percha and sealer from root canals, including hand files, rotary systems, and softening of the material using chemicals or heat (3). However, residual debris in the canal walls after re-instrumentation with different techniques is an ongoing issue that affects treatment outcome (2).…”

This study aimed to evaluate superficial defects and the composition of Reciproc R25 and ProTaper Retreatment file systems (Dentsply Maillefer, Ballaigues, Switzerland) used for retreatment. A total of 100 maxillary incisor teeth were randomly divided into the following two groups: Reciproc R25 (n = 25) and ProTaper Retreatment instrument (n = 75) groups. The nickel-titanium (Ni-Ti) compositions of the files before and after use were analyzed using energy dispersive X-ray spectrophotometry (EDX). Chi-square, Mann-Whitney U, and Kruskal-Wallis tests were used to analyze the data. ProTaper Retreatment instrument group showed a significantly higher number of defects than the Reciproc group (P < 0.05). No instrument fracture was detected. The presence of debris was observed in both groups before use, although the level was significantly higher in the ProTaper Retreatment group, which consisted of metals (P < 0.05). There was no significant difference between new and used instruments with regard to Ni-Ti composition (P < 0.05). EDX analysis showed that both the Reciproc and ProTaper Retreatment instruments had a Ni-Ti composition that was within the standards specified by the American Society of Testing and Materials. This study confirmed the use of both the Reciproc R25 file and ProTaper Retreatment file system for root canal filling removal in straight root canals as a safe procedure.

“…In cases of inadequate cleaning or filling of the root canal system, procedural errors, or reinfection of the primary sealed root canal caused by coronal or apical leakage, retreatment is indicated. [3][4][5] A large portion of the guttapercha and sealers should be removed in order to reach the bacteria and tissue residues that are the causes of endodontic failure.…”

“…Therefore, the use of solvent greatly facilitates the removal of filling material. 4 An ideal solvent for endodontic retreatment balances the requirements of an acceptable level of clinical safety, level of toxicity and tissue destruction, and chemical capacity for dissolution.…”

Aim:To evaluate the solubility of five different root canal sealers (AH Plus Jet, RealSeal SE, MTA Fillapex, Tubli-Seal, and Acroseal) in chloroform, eucalyptol and Endosolv-E solvents. Materials and methods:Ninety root canal sealer samples were prepared and then divided into three groups for immersion in a solvent for 2, 5 or 10 minutes. The mean values of the root canal sealers' dissolution in the solvents were obtained by the difference between the preimmersion original weight and the post-immersion weight on a digital analytical scale. Data were statistically analyzed by a Kruskal-Wallis test with a Bonferroni correction. Results:Chloroform was a more effective solvent than eucalyptol or Endosolv E for all root canal sealers, except for RealSeal SE, at all time points (p < 0.003). RealSeal SE was the least soluble sealer in all solvents at all time points. Conclusion:Chloroform demonstrated a superior ability over other solvents in dissolving canal sealing materials, and eucalyptol was found to be the least effective solvent in this study. Clinical significance:This study can help to the clinicians about which solvent should be preferred for solving the filling materials in retreatment cases.
