A 3-year comparison of dental anxiety treatment outcomes: hypnosis, group therapy and individual desensitization vs. no specialist treatment.

Outcomes of hypnotherapy (HT), group therapy (GT) and individual systematic desensitization (SD) on extreme dental anxiety in adults aged 19-65 yr were compared by regular attendance behaviors, changes in dental anxiety and changes in beliefs about dentists and treatment after 3 yr. Treatment groups were comparable with a static reference control group of 65 anxious patients (Dental Anxiety Scale > or = 15) who were followed for a mean of nearly 6 yr. After 3 yr, 54.5% of HT patients, 69.6% of GT patients and 65.5% of SD patients were maintaining regular dental care habits. This was better than the 46.1% of the reference group, who reported going regularly to the dentist again within the cohort follow-up period, and 38.9% of a control subgroup with observation for 3 yr. Women were better regular attenders than men at 3 yr. Specialist-treated regular attenders were significantly less anxious and had more positive beliefs than regular attenders from reference groups. There were few differences between HT, GT and SD after 3 yr. It was concluded that many patients can, on their own, successfully start and maintain regular dental treatment habits with dentists despite years of avoidance associated with phobic or extreme anxiety. However, it also appears that these patients had less success in reducing dental anxiety and improving beliefs about dentists long-term than did patients who were treated at the specialist clinic with psychological strategies.
