Acupuncture is amongst the most successful interventions for reducing anxiety in dental patients, according to American authors.  Their systematic review covered 408 articles, with a total of 50,343 patients undergoing 14 different types of non-pharmaceutical intervention to alleviate dental anxiety.  Music, cognitive behavioural therapy, relaxation, massage, acupuncture/acupressure, hypnosis and natural sounds were the most successful interventions, reducing anxiety in over 70% of experiments.
