Abstract

Introduction: This study aims to determine if intraoral 850 nm LED irradiation could reduce the duration of lower anterior crowding alignment.

Methods: In a parallel-designed, randomized controlled clinical trial 60 patients with 2 to 6 mm of lower incisor crowding who need non-extraction treatment, were randomly assigned to the intervention and control groups by block randomization (36 females, 24 males, mean age: 19.93 ± 3.05). MBT brackets (0.022 × 0.28-inch) were bonded for both groups and the NiTi wires in sequences were put in place until correction of crowding. The intra-oral LED device with a wavelength of 850 nm and power density of 70 mW/cm² was used for 5 min per day in the intervention group. The control group did not receive any light. The primary outcome was the duration of crowding correction. The patient's pain according the modified McGill pain questionnaire was the secondary outcome. The Cox regression model was used to compare groups. Mann-Whitney test was used for pain analysis.

Results: The crowding at baseline was the same between the two groups (P > 0.05). Duration of treatment in the intervention group was 104.7 days (95% CI: 95.6 -113.8) and significantly shorter than 161.9 days (95% CI: 151.5 -171.2) in the control group. The control group experienced a significantly higher pain score of 6.8 (95% CI: 6.1-7.5) immediately after archwire placement than the intervention group 5.4 (95% CI: 4.6-6.3).

Conclusions: Intra-oral LED 850 nm significantly decreased the relieving time of lower incisor crowding by up to 36% and reduced pain experience.

850 nm LED照射对拥挤的下颌前牙排列的影响：一项随机对照临床试验。

简介：本研究旨在确定口腔内850 nm LED照射是否可以减少下前牙拥挤对齐的持续时间。方法：采用平行设计、随机对照临床试验，将60例2 ~ 6mm下切牙拥挤且需要非拔牙治疗的患者，采用分组随机法随机分为干预组和对照组（女性36例，男性24例，平均年龄19.93±3.05岁）。两组均粘接MBT托架（0.022 × 0.28英寸），按顺序放置NiTi丝，直至矫正拥挤。干预组使用波长为850 nm、功率密度为70 mW/cm2的口腔内LED装置，每天使用5 min。对照组没有接受任何光线。主要结局是拥挤矫正的持续时间。患者根据改良的McGill疼痛问卷的疼痛程度为次要观察指标。采用Cox回归模型进行组间比较。采用曼-惠特尼检验进行疼痛分析。结果：两组患者在基线处的拥挤程度相同（P < 0.05）。干预组治疗时间为104.7天（95% CI: 95.6 ~ 113.8），显著短于对照组的161.9天（95% CI: 151.5 ~ 171.2）。对照组的疼痛评分为6.8 (95% CI: 6.1-7.5)，高于干预组的5.4 （95% CI: 4.6-6.3）。结论：口腔内LED 850 nm可使下门牙拥挤缓解时间缩短36%，减轻疼痛体验。
