Purpose:
To evaluate the effect of Mtwo NiTi files in the management of calcified root canals.
Methods:
Thirty-five calcified root canals from 21 cases unsuccessfully prepared with C-Pilot files and EDTA were treated with Mtwo NiTi files and EDTA. The data was analyzed with SAS 9.4 software package.
Results:
Twenty-three calcified root canals were successfully prepared. The success rate was 65.71%. Instrument separation occurred in 4 root canals, and ledge occurred in 3 root canals. Categorized by calcified position, the success rate of three groups had no significant differences (P>0.05).
Conclusion:
Mtwo NiTi files can effectively process calcified root canals.
