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.
