Effect of constant currents on orthodontic tooth movement in the cat

Constant 10 muA currents were applied to the mandibles of 12 cats via electrodes implanted mesial and distal to premolars undergoing orthodontic treatment. A third were moved toward the cathode, a third were moved toward the anode, and a third were moved in the absence of an applied field. No significant difference in total movement was seen at the end of five weeks.
