Product Name:

K3XF Rotary NiTi Files

Manufacturer :

SybronEndo

K3XF is a rotary file made from R-phase wire(rhombohedric transformation). The file is ground similar to the conventional K3 files. This file has a modified triple U shaped cross section with only one radial land touching the canal wall at once. The other 2 radial lands has only a point contact enabling canal centering along with less canal contact and binding. The file has to be used in pecking motion (motion of 2 mm pecks) which enables easy progress to the apical portion. Auguring of debris is beautiful.The product gives 4% and 6% files which provide versatility to treat and shape canals. An array of tip sizes enables effective cleaning of the root canal system.

Summary

The Good

Tapers and tip sizes provide versatility, flexibility is a positive benefit, good cleaning efficiency.

The Bad

Useful for 7 cases exactly. ISO25 4% file is a little weak in terms of cyclic and torsional fatigue. Shifting canal taper from 4% to 6% taper is eventually difficult.

The Bottom Line

It's a relatively better file than other comparable products and seems to be cost effective. I recommend this system if you have enough patience and the skill to use it.
