OBJECTIVE
To investigate the relationship between a micropulse vibration device and pain perception during orthodontic treatment.
MATERIALS AND METHODS
This study was a parallel group, randomized clinical trial. A total of 58 patients meeting eligibility criteria were assigned using block allocation to one of two groups: an experimental group using the vibration device or a control group (n = 29 for each group). Patients used the device for 20 minutes daily. Patients rated pain intensity on a visual analog scale at appropriate intervals during the weeks after the separator or archwire appointment. Data were analyzed using repeated measures analysis of variance at α = .05.
RESULTS
During the 4-month test period, significant differences between the micropulse vibration device group and the control group for overall pain (P = .002) and biting pain (P = .003) were identified. The authors observed that perceived pain was highest at the beginning of the month, following archwire adjustment.
CONCLUSION
The micropulse vibration device significantly lowered the pain scores for overall pain and biting pain during the 4-month study period.
目的
研究微脉冲振动装置与正畸治疗期间疼痛感知之间的关系。
材料与方法
本研究为平行组随机临床试验。共有58例符合入选标准的患者采用区组随机化法分为两组：使用振动装置的试验组或对照组（每组n = 29）。患者每天使用该装置20分钟。在放置分离器或弓丝后的几周内，患者在适当的时间间隔使用视觉模拟量表对疼痛强度进行评分。采用重复测量方差分析对数据进行分析，α = 0.05。
结果
在4个月的试验期内，微脉冲振动装置组与对照组在总体疼痛（P = 0.002）和咬合疼痛（P = 0.003）方面存在显著差异。作者观察到，在弓丝调整后的月初，疼痛感知最高。
结论
在4个月的研究期内，微脉冲振动装置显著降低了总体疼痛和咬合疼痛的疼痛评分。
