Five years after completing a controlled, randomized treatment trial comparing the effect of nitrous oxide sedation (NO), cognitive therapy (CT), and applied relaxation (AR), all 62 patients who had participated were invited to a follow-up questionnaire study. Forty-three responded. All participants had been to the dentist during the follow-up period. Mean scores (s) on Corah's Dental Anxiety Scale (CDAS) and Symptom Checklist 90 Revised (SCL-90-R, a measure of general psychological distress) were 10.4 (4.1) and 0.35 (0.34), respectively. There were no between-group effects. Significant changes across the assessment phases (at enrollment, after treatment, and 5 years after) were found for both dental fear and general distress (CDAS: F = 137.8, P < 0.01; SCL-90-R: F = 12.5, P < 0.01). However, no significant changes between measures obtained after treatment and at follow-up emerged. Seven participants (3 from the NO group, 2 from the CT group, and 2 from the AR group) had CDAS scores above 14, indicating a recurrent or continual dental fear problem. The majority (81%) assessed the dental fear treatment received 5 years previously to have been useful for them. In conclusion, the favorable effects on dental fear and general psychological distress continued at 5-year follow-up for all treatment groups.
在完成一项比较一氧化二氮镇静（NO）、认知疗法（CT）和应用放松疗法（AR）效果的对照随机治疗试验五年后，邀请了所有参与的62名患者参加一项随访问卷调查研究。43人做出了回应。所有参与者在随访期间都看过牙医。在科拉牙科焦虑量表（CDAS）和症状自评量表90修订版（SCL-90-R，一种一般心理困扰的测量方法）上的平均得分分别为10.4（4.1）和0.35（0.34）。组间没有差异。在评估阶段（入组时、治疗后和5年后），牙齿恐惧和一般困扰均有显著变化（CDAS：F = 137.8，P < 0.01；SCL-90-R：F = 12.5，P < 0.01）。然而，治疗后和随访时获得的测量结果之间没有显著变化。7名参与者（3名来自NO组，2名来自CT组，2名来自AR组）的CDAS得分高于14，表明存在复发性或持续性牙齿恐惧问题。大多数人（81%）认为5年前接受的牙齿恐惧治疗对他们有用。总之，在5年随访时，所有治疗组对牙齿恐惧和一般心理困扰的积极影响仍然存在。
