“…Patil et al . [ 21 ] in a study reported that rotary instruments are more beneficial than hand instruments for GP retrieval. Due to the frictional heat produced by rotary instruments, which causes the gutta-percha to soften and make it easier to reach the working length, rotary retreatment systems in the current study left less debris in the root canal than manual retreatment systems.…”

Aim: To evaluate the efficacy of Neo-endo, Hyflextm retreatment file systems, and H-files for removing gutta-percha from root canal treated tooth. Materials and Methods: Thirty extracted single-rooted human teeth with a single canal were opted. The shaping of the root canals was done with pro-taper universal files and later obturated. The samples were grouped based on the file system chosen for removing the obturating material: Group I-H-files; Group II-Neo-endo retreatment files; Group III-Hyflex™ retreatment files. The quantity of remaining gutta-percha still present after the retreatment procedure was assessed under a stereomicroscope. One-way Analysis of Variance (ANOVA) was used to statistically analyze the data. Results: Hyflex™ files left less remaining filling material than with Neo-endo and H-files. Conclusion: The Hyflex™ retreatment files were most efficient in removing the gutta-percha from the root canal.

The objective of the present in vitro work was to investigate the effectiveness and time required for the removal of calcium silicate-based sealer using two rotary retreatment systems. Sixty extracted, single-canal, lower premolars were used. After obturation using the single-cone technique with calcium silicate-based sealer, samples were divided into four groups according to the technique of desobturation: Group 1 (G1): D-Race; Group 2 (G2): D-Race followed by the use of XP–Endo Finisher R; Group 3 (G3): Protaper Universal Retreatment; and Group 4 (G4): Protaper Universal Retreatment followed by the use of XP–Endo Finisher R. Cone beam computed tomography (CBCT) images were used to calculate the remaining filling materials at the middle and apical thirds. Times required to perform each method were recorded. Scanning electron microscopy (SEM) and digital microscopy were used to evaluate the remaining filling materials. Data were statistically analyzed using the t-test and one way ANOVA on ranks tests. No statistically significant difference was found between G1 and G3 after CBCT observations (p > 0.05). Xp-Endo Finisher R significantly increased the ability to remove materials regardless of the initially used retreatment system (p < 0.05). Statistically significant longer time was found in G3 and G4 compared to G1 and G2, respectively (p < 0.05), to reach the full working length. No retreatment system was able to totally remove the calcium silicate-based sealer from the root canal at the middle and apical thirds (p > 0.05). Digital microscopy demonstrated that the residual materials were the remaining sealers on the canal walls. SEM showed the mineral depositions of calcium silicate materials onto the canal walls and into the dentinal tubules. However, that calcium silicate materials provide mineral deposition into the dentinal tubules might indicate that the traditional irrigants could not be sufficient to remove calcium silicate-based materials from the root canal, and other agents should be used to make retreatment considerably easier.

INTRODUCTION: Non-surgical endodontic treatment is the best way to re-establish sound periapical tissues after reinfection or inefficient treatment of a previously obturated teeth due to apical or coronal leakage. It requires regaining the accessibility to the root canal system by removing the initial root canal filling, more cleaning, and reobturation. THE AIM OF THE STUDY: Is to compare the cleaning productivity of the XP Endo Finisher R (XPR) and the Endo Activator (EA) after retreatment using the scanning electron microscope (SEM). MATERIAL AND METHODS: This study was performed on forty-five mesiobuccal canals of mandibular first molars. All teeth were obturated then retreated using D-Race rotary files. Teeth were haphazardly divided into three groups according to the cleaning method used: Group (1): XPR. Group (2): EA. Group (3): control group (no final cleaning). All the teeth were sectioned longitudinally and canal cleaning ability was assessed by the SEM. Data were statistically analyzed using Chi-Square and Kruskal Wallis tests. RESULTS: Significant differences in the smear layer and debris removal between both XPR and EA groups and the control group were detected (P<0.05). CONCLUSIONS:The XPR and the EA are both efficient in removing the debris and the smear layer after retreatment. Moreover, the XPR performed better than the EA. None of the investigated techniques were able to totally remove the filling material.
