低能量激光疗法应用于正畸尖牙的远中移动:一项Meta分析

Effect of Low-Level Laser on Orthodontic Canine Distal Movement:A Meta-Analysis

目的:依据低能量激光作用于尖牙的远中移动效果来评判低能量激光加速正畸牙齿移动的有效性。方法:本次Meta分析步骤以PRISMA声明为依据,应用计算机检索PubMed、Cochrane Library、Embase、CNKI、维普以及万方等数据库,检索时间为2000年1月—2021年12月,汇总所有随机对照试验,应用RevMan5.3和STATE软件进行Meta分析。结果:共纳入7篇研究,累计224个样本量。Meta分析结果显示:与对照组相比,低能量激光组在治疗后7 d(WMD=0.360,95%CI=0.330~0.389,P<0.05),28 d(WMD=0.353,95%CI=0.141~0.566,P<0.05),60 d(WMD=0.301,95%CI=0.101~0.502,P<0.05),90 d(WMD=0.414,95%CI=0.179~0.650,P<0.05)尖牙远中移动距离显著增加,差异具有统计学意义。结论:低能量激光作为正畸治疗辅助手段,能有效促进正畸牙齿移动。

Objective:the effect of low-level laser on Canine distal movement was evaluated to evaluate the efficiency of low-level laser on accelerating orthodontic tooth movement.Methods:this meta-analysis follows the PRISMA statement.We searched PubMed,Cochrane Library,Embase,CNKI,VIP,and WanFang,and the search was conducted between January 2000 and December 2021.We pooled all randomized controlled trials and conducted a meta-analysis using Revman 5.3 and STATE.Results:a total of 224 samples were included in 7 studies.The results of meta-analysis show that:compared with the control group,the low-level Laser group within 7 days after treatment(WMD=0.360,95%CI=0.330-0.389,P<0.05);Within 28 days(WMD=0.353,95%CI=0.141-0.566,P<0.05),within 60 days(WMD=0.301,95%CI=0.101-0.502,P<0.05),within 90 days(WMD=0.414,95%CI=0.179-0.650,P<0.05),the canine movement distance increased significantly.Conclusion:as an auxiliary means of orthodontic treatment,Low-level laser can effectively accelerate orthodontic tooth movement.
