Research Type




Background: Acupuncture was evaluated by the US National Institutes of Health (NIH) in 1997 and deemed an effective complementary and alternative medicine (CAM) for the treatment of myofascial pain, chronic pain, vomiting, nausea, and analgesia. Acupuncture has been shown to be effective for pain reduction in headaches, postoperative dental pain, and myofascial pain. Objective: To test the hypothesis that acupuncture would decrease the pain from electrical stimulation of the front teeth. Design, Setting, and Patients: At Universidad Mayor, Santiago, Chile, 40 volunteers (21 men and 19 women) were recruited to participate in this study. They were randomly assigned to receive either placebo or real acupuncture. Intervention: The real group received acupuncture at LI 4 and the placebo group also received placebo acupuncture at L14, both for 15 minutes. Both groups had an electric pain stimulation applied to the 4 upper front teeth, before and after acupuncture or placebo acupuncture was performed. Results: To analyze the results, a t test was used, comparing placebo vs real acupuncture on each front tooth, and also to compare left incisors with right incisors. No significant differences in pain reduction were found between the volunteers who received real acupuncture and those who received the placebo, or between left and right incisors. Conclusion: Acupuncture performed at LI 4 had no effect on the electric pain stimulation of the 4 upper front teeth.
