NiTi file challenge

In this Video, I challenged three NiTi File systems which I have used in my clinical practice, namely: 1. ProTaper Universal (Dentsply Sirona), 2. TF-Adaptive (Kerr Endo), 3. Bassi Logic (BassiEndo).
Honestly, it is not a fair comparison as they are in different generations in NiTi file history.
However, it showed that the new ‘Controlled Memory’ NiTi file systems such as Bassi Logic, have much higher strength and flexibility, resulting in greater resistance to cyclic fatigue, than other heated-treated and conventional NiTi instruments. As a result, they are safer in root canal preparation.
