Abstract

Objective: This study aims to evaluate the effect of low-level laser therapy (LLLT) on leveling mandibular anterior crowding and associated pain levels.

Methods: This double-blinded, parallel, randomized clinical trial included 30 participants who were randomly assigned to the laser group or the control group, with Little's irregularity index of 4-8 mm in the mandibular canine-canine region. Nickel-titanium archwires measuring 0.012 inches were tied with elastomeric ligatures and changed every 14 days throughout the leveling process. The leveling duration was recorded in days, from the bonding application to the end of leveling. Irradiation was performed at an 810-nm wavelength using a gallium-aluminum-arsenide diode laser device with a power output of 100 mW and an energy density of 8 J/cm². Laser applications were performed after archwire ligation (day 0), on days 3, 7, and 14 and every 14 days until leveling was completed. The leveling duration was calculated, and pain levels were evaluated using a visual analogue scale (VAS) after archwire ligation (hour 0), at hours 2 and 6 and on days 1, 3, 7, 14, and 21.

Results: The leveling duration showed no significant differences between the laser and control groups (p=0.170). Group comparison results of the VAS scores at hour 6 (p=0.001) and day 1 (p=0.006) exhibited significantly reduced pain levels in the laser group compared with the control group.

Conclusion: Although LLLT is not effective in reducing the leveling duration, it significantly reduces pain levels at hour 6 and on the 1st day.

低水平激光治疗下颌前牙拥挤的疗效评价。
目的:探讨低水平激光治疗(LLLT)对调节下颌前侧拥挤及相关疼痛水平的影响。方法:采用双盲、平行、随机临床试验,30例患者随机分为激光组和对照组,下颌犬齿区Little’s不规则指数为4 ~ 8 mm。在整平过程中,0.012英寸的镍钛拱线用弹性绳系住,每14天更换一次。调平持续时间以天为单位记录,从bonding应用到调平结束。使用功率输出为100 mW、能量密度为8 J/cm²的砷化镓铝二极管激光器件在810 nm波长下进行照射。在弓丝结扎后(第0天)、第3天、第7天和第14天进行激光应用,每14天进行一次激光应用,直到整平完成。计算水平持续时间,并使用视觉模拟量表(VAS)评估弓丝结扎后(0小时)、2小时和6小时以及第1、3、7、14和21天的疼痛水平。结果:激光组与对照组调平时间差异无统计学意义(p=0.170)。第6小时(p=0.001)和第1天(p=0.006) VAS评分的组间比较结果显示,与对照组相比,激光治疗组疼痛程度明显减轻。结论:LLLT虽不能有效缩短调平时间,但可显著降低第6小时和第1天的疼痛程度。
