Background: One of the tedious processes is the removal of gutta-percha from the infected root canal. Different techniques and instruments are available for retreatment. The aim of this in-vitro study was to compare the efficacy of D-RaCe files and Manual H-files in removing filling material from the root canals. Materials & methods: The present study included evaluation and comparison of efficacy of D-RaCe files and Manual H-files in removing filling material from the root canals. A total of 50 freshly extracted mandibular first premolars were included in the present study. Teeth were divided broadly into two study groups with 25 premolars in each group as follows: Group 1: Included teeth in which retreatment were done using D-RaCe files, Group 2: Included teeth in which retreatment were done using Hedstrom files with Solvent. Retreatment was done in teeth of both the study groups according to their respective groups. Assessment of remaining root canal filling material was done in all the teeth specimens of both the study groups. Stereomicroscope was used for assessing the area of remaining root canal filling material. Results: Mean area of remaining root canal filling materials in group 1 and group 2 was 8.45 and 16.25 respectively. Significant results were obtained while comparing the mean area of remaining root canal filling materials in between two study groups. Conclusion: Rotary systems are better in comparison to H-file systems in retreatment cases.
