American authors lead by the University of Detroit, have concluded acupuncture helps dental anxiety. The reviewers surveyed 408 articles, covering over 50000 patients trying 14 different non-pharmaceutical interventions. Acupuncture, acupressure, music, CBT, relaxation and hypnosis were among the most successful. Acupuncture and acupressure, although not widely tested, were given an effectiveness rating of 100%.
