A practice-based study was carried out to assess the comparative effectiveness and acceptability of standardised hypnosis, hypnosis with individualised imagery, cognitive behavioural treatment (CBT) and general anaesthesia (GA) in the treatment of dental phobia.
A 4-group design was used with 4 repeated measurement occasions. Of an initial total of 137 dental phobics, 77 completed the study with sample sizes of between 14 and 29 patients in the 4 groups. Participants completed questionnaires of dental anxiety at the beginning of the trial, before and after the first dental appointment and again before the second dental appointment a week later.
Standardised hypnosis evidenced a significantly higher rate of premature termination of treatment than CBT. The completer analysis showed a significant reduction of dental anxiety after CBT and individualised hypnosis compared to the GA condition. The intent-to-treat analysis showed significant improvement only after CBT.
The results suggest that CBT is the treatment of choice in dental phobia when taking both effectiveness and acceptability into account.
本基于实践的研究旨在评估标准化催眠、个体化意象催眠、认知行为疗法（CBT）和全身麻醉（GA）在治疗牙科恐惧症方面的比较效果和可接受性。
采用 4 组设计，共进行了 4 次重复测量。在最初的 137 名牙科恐惧症患者中，有 77 名完成了研究，4 组的样本量在 14 至 29 名之间。参与者在试验开始时、第一次牙科预约前、第一次牙科预约后和一周后的第二次牙科预约前完成了牙科焦虑问卷。
标准化催眠的治疗提前终止率明显高于 CBT。完成者分析显示，与 GA 组相比，CBT 和个体化催眠后牙科焦虑显著降低。意向治疗分析仅显示 CBT 后有显著改善。
结果表明，在考虑有效性和可接受性的情况下，CBT 是牙科恐惧症的首选治疗方法。
