Abstract: Introduction
We attempted to get an objective index of pain, giving electro-nocistimulus to the tooth and making a comparison between the stimulus rate and subjective pain. We examined variations of the response to stimulus under this low-frequency electric treatment.
Method
Treated were single healthy upper incisors of 14 medical doctors. Fixing a silver electrode of 4mm² on each tooth and an indifferent electrode on the buccal surface of the same side, stimulation was applied.
Effect
Three categories of pain, i. e. pre-pain, tolerable pain and intolerable pain were established for the purpose of this study. We made use of these categories as an objective index of pain. It was also evident that, under low frequency electric treatment to acupoints of acupuncture anesthesia, there were variations in intolerable pain. We examined variations of this pain.
Conclusion
It was concluded that there were two types of objects, i. e. the effective and the ineffective.
Intolerable level was affected by the low frequency electric treatment and pain was alleviated.
