Abstract
Dental electronic analgesia apparatus and methodology employs a transcutaneous electronic wave to suppress perceived pain during trauma associated with dental procedures. A first electrode is placed on the buccal side of the gum adjacent the work area, and second electrodes are disposed on the web of the ipsalateral hand and on the ipsalateral trapezius origin. An electronic current wave comprising relatively high frequency pulses with a low frequency amplitude modulation is then applied between the first to the second electrodes. The apparatus of the instant invention has been found to block pain in most subjects with a low level current without any chemical intervention--or with a reduced dosage of local anesthesia.
