The invention control system provides for rotating a file clockwise or counterclockwise through a desired first arc of rotation and, next, sequentially rotating the instrument in the opposite direction of the first arc of rotation through a second arc of rotation, wherein the first arc of rotation exceeds the second arc of rotation such that sequentially occurring rotations cause debris material removed in cleaning the canal to be ejected upwardly from the clean surfaces as such file is advanced in cleaning the canal.
