Doctor, I hope your work is going well. While advancing with perfect in calcified teeth, I sometimes break glider and glider pro files in the apical third despite sufficient coronal enlargement and using crowndown. I also keep the torque and rpm values low as I proceed. How can I prevent this complication?

In 1 year, altogether, it has happened in 3–5 teeth, but it is an annoying issue.

Do you think it makes sense to treat these files as single-use in calcified teeth?

With Glider files, the speed must not be kept low.

10 04 min 250 rpm

08 03 min 300 rpm

In difficult teeth, they need to be treated as single-use instruments.
