The influence of naloxone on dental pain threshold elevation produced by peripheral conditioning stimulation at high
Brain Research
|June 29, 1981
Abstract:
The phasic dental pain threshold elevation produced by high-frequency transcutaneous electrical nerve stimulation (TENS) in healthy humans was not abolished by naloxone. A prolonged (20 min) high-frequency TENS did not cause any tonic pain threshold elevation. The results indicate that opioid-dependent systems have only a minor if any contribution to alleviation of experimental pain during high-frequency TENS.
