<prompt> Balanced force technique can be described as:Positioning and preloading an instrument with a clockwise rotation and shaping with a counter clockwise rotation.Insertion with a quarter turn clockwise rotation with slight apical pressure.Cutting 180 degree to 270 degree counterclockwise rotation with apical pressure.All of the above.  <response>: Balanced Force TechniqueBalanced force technique was introduced by Roane et al, in 1985. In this technique, flex-R-files, flex-O files, or any other flexible files with a modified non-cutting tip are used.Positioning and preloading an instrument with a clockwise rotation and shaping with a counter clock wise rotationInsertion with a quarter-turn clockwise rotation with slight apical pressure Cutting 180-270 counterclockwise rotation with apical pressure.
