Chandrakanth Majeti, Pradeep B, Saikrishna T

Background: Success is the expected outcome after root canal treatment (RCT), regardless of the clinical conditions. Several techniques have been proposed to remove filling materials from root canal system, including the use of endodontic hand files, Nickel Titanium rotary instruments, Gates Glidden burs, heated instrument, ultrasonic instruments, laser, and use of adjunctive solvents. Hence; we planned the present study to compare the efficacy of D-RaCe files and Manual H-files in removing filling material from the root canals. Materials & methods: A total of 20 freshly extracted mandibular premolars were included in the present study. Decoronation of the teeth specimen was done upto a length of 15 mm from the apex. Root canal therapy was performed followed by obturation with gutta-percha and AH Plus sealer using cold lateral compaction technique. All the specimens were divided broadly into two study groups with 10 specimens in each group as follows: Group A: D-RaCe files- Retreatment was done by D-RaCe files, and Group B: Hedstrom files with Solvent- Retreatment were done with Hedstrom files. Evaluation of remaining root canal filling material was done. All the results were analysed by SPSS software. Result: Percentage of remaining root canal filling material among specimens of group A was 7.11%. Percentage of remaining root canal filling material among specimens of group B was 16.22%. Significant results were obtained while comparing the mean remaining root canal filling material in between the two study groups. Conclusion: Root canal wall retracement is more effective with D-RaCe files in comparison to  Manual Hedstrom files.
