Abstract:
Objective:To evaluate the effects of low level laser therapy(LLLT)on accelerating tooth movement and reducing pain during orthodontic treatment.Methods:26 patients with malocclusion of class Ⅱ,division 1 were included.Maxillary teeth on left and right sides were selected randomly as the experimental side and control side.Dental arches of experimental side received the irra-diation of LLLT with 7.5 J/cm2 for each point,10 points for each tooth,and the control side received placebo treatment,with the la-ser light off.The pain and the rate of teeth movement on experimental and control sides were compared.Results:The mean score of pain at the control side was significantly higher than that of the experimental side in the 7 days(P＜0.001).The average movement rate of the experimental group was higher than that of the control group(P＜0.05).Conclusion:LLLT is effective in accelerating tooth movement and reducing the related pain.
