The effects of two instrumentation techniques for VDW. Rotate instruments on the apical extrusion of debris and irrigants: An in vitro study

, 2023
Objectives:This study compared the amount of apically extruded debris and irrigant using VDW. ROTATE instruments with different kinematics (continuous rotation and reciprocation motion) and the ProTaper Gold system.Methods:Sixty extracted mandibular premolar teeth were selected. The teeth were prepared for the agar gel model.
