Psychophysiological therapy vs. hypnotherapy in the treatment of patients with dental phobia.
The aim of this study was to compare two different modes of behaviorally-oriented therapies for dental fear. The subjects were chosen consecutively from the waiting-list of a Dental Fears Research and Treatment Clinic. In addition, a control group was selected from patients treated under general anesthesia to compare levels of dental and general fear with the experimental groups. Twenty-two women, with a mean age of 31.8 yr, were included and randomly assigned to two groups. The median time of avoidance of dental care was 9.5 yr. One group received hypnotherapy (HT) and one group a behavioral treatment based on psychophysiological principles (PP). Both therapies included eight sessions followed by standardized conventional dental test treatments. Pre- and posttreatment measures were dental fear, general fear, mood, and patient behavior. Nine patients were not able to conclude the treatment sessions (6 HT and 3 PP); these patients did not differ significantly from the remaining patients before treatment. The PP group reported a statistically significant decrease in dental fear as well as a rise in mood during dental situations, as opposed to the HT group. General fear levels decreased but not significantly. Eleven patients completed conventional dental treatment according to a dentist's behavioral rating scale, indicating that they were relaxed, and no problems occurred during the treatments. These patients were referred to general practitioners within the community dental service. In conclusion, this small size study showed that a majority of the patients, who accomplished the behavioral therapy and the dental test treatments, became less fearful of dental care and were able to manage conventional dental care, including changing dentist.
