Cam mechanisms play a pivotal role in converting rotational motion into precise reciprocating movement, with their performance being ultimately defined by the geometry of the cam profile. In recent ...

With endodontic files, reciprocating mechanisms are claimed to improve cyclic resistance and fatigue by reversing the rotation direction for short periods of time. It is also claimed that this helps ...
