Hypnosis, Dental

Hypnotic suggestibility has been described as a powerful predictor of outcomes associated with hypnotic interventions. However, there have been no systematic approaches to quantifying this effect across the literature. This meta-analysis evaluates the magnitude of the effect of hypnotic suggestibility on hypnotic outcomes in clinical settings. PsycINFO and PubMed were searched from their inception through July 2009. Thirty-four effects from 10 studies and 283 participants are reported.

OBJECTIVE: Hypnosis is widely used in medicine and dentistry, but many practitioners still consider it as a mysterious technique. Thus, a systematic review was conducted to assess the effects of hypnosis during dental treatment. METHODS: A literature search was conducted on PubMed (1981-2012) to retrieve references, written in French or English, reporting controlled clinical studies that have evaluated any type of hypnosis. The quality of included studies was assessed by evaluating randomisation, blindness and drop-outs.

AIMS: To conduct a systematic review and meta-analysis to evaluate the effectiveness of hypnosis/relaxation therapy compared to no/minimal treatment in patients with temporomandibular disorders (TMD). METHODS: Studies reviewed included randomized controlled trials (RCTs) where investigators randomized patients with TMD or an equivalent condition to an intervention arm receiving hypnosis, relaxation training, or hyporelaxation therapy, and a control group receiving no/minimal treatment.
