Abstract
The objective of this study is to evaluate the cyclic and torsional fatigue resistance of a new reciprocating instrument, CC One Blue (CC 25.08 - Bondent, Shanghai, China), and compare it with the Reciproc Blue instrument (RB 25.08 - VDW, Munich, Germany). A total of 40 instruments (n=20) will be required for the mechanical tests of this study. The cyclic fatigue test will be conducted in…
