An investigation into the relative efficiency of dextro-rotating and laevo-rotating spiral paste fillers in the southern hemisphere.
Much published work evidences the differences of object-rotation which occur between the northern and the southern hemispheres; particularly commonly the evacuation of water or other liquids through a hole. This paper reports the results of an investigation into the efficiency with which a conventionally-wound clockwise-spiral root canal paste filler obturated experimentally instrumented root canals in the southern hemisphere as compared with those using a filler wound with an anticlockwise spiral.
