TMJ To compare the effect of real acupuncture and sham acupuncture in the treatment of temporomandibular joint myofascial pain, in order to establish the true efficacy of acupuncture.
A double-blind randomized controlled trial conducted in the TMD Clinic, at the School of Dentistry, The University of Manchester. Twenty-seven patients were assigned to one of two treatment groups. Group 1 received real acupuncture treatment whilst Group 2 received a sham acupuncture intervention. Both the assessor and the patient were blinded regarding the group allocation. Baseline assessment of the outcome variables was made prior to the first treatment session and was repeated following the last treatment.
The results demonstrated that real acupuncture had a greater influence on clinical outcome measure of TMJ MP than those of sham acupuncture, and the majority of these reached a level of statistical significance.
Acupuncture had a positive influence on the signs and symptoms of TMJ MP. In addition, this study provides evidence that the Park Sham Device was a credible acupuncture control method for trials involving facial acupoints.

Acupuncture for Treating Temporomandibular Dysfunction: Retrospective Study on Safety
“4. Discussion and Conclusions. The results of this study showed that Chinese acupuncture was safe as administered here and was efficient in alleviating pain in patients suffering from TMD not caused by an osseous source. In approximately 90% of these patients, a statistically significant pain alleviation was observed, with the pain completely gone in most patients.”
TMJ & Acupuncture
After 1-2 courses of treatment, 102 cases were judged cured. This was defined as the disappearance of symptoms, a return to normal of jaw movement, and normal opening and closing of the mouth. Twenty-nine cases were deemed to have registered a marked effect. This meant that their symptoms were markedly decreased and that the opening of their mouths had returned to normal. Another 15 patients were judged to have gotten some effect. This meant that their symptoms had decreased somewhat and they could still not open their mouths as wide as they had before their disorder. In addition, six cases got no effect, meaning that they did not experience any improvement. Of those who were judged cured, 72 were cured within one course of treatment, while 29 required two courses.
