目的：探讨不同能量参数CO2弱激光局部照射对尖牙向远中移动过程中牙齿疼痛及牙齿移动速度的影响。方法选择60例拔牙矫正的错合畸形患者，在牙列排齐整平后，使用0.018英寸不锈钢圆丝，用链状皮圈以150 g力量拉上颌尖牙向远中移动的过程中以两种不同强度能量参数的CO2弱激光对右侧尖牙根部区域进行照射，左侧作为对照侧。使用视觉模拟评分法（ VAS）评价CO2弱激光局部照射对牙齿疼痛程度的影响。用游标卡尺测量尖牙远移的距离和支抗丧失（第一磨牙近中移动距离）的程度，评价两种能量参数CO2弱激光局部照射对尖牙向远中移动的过程中牙齿移动速度的影响。结果两种能量参数均能减轻正畸牙齿疼痛程度。高能量参数组激光能有效地加快牙齿移动速度，而低能量参数组没有明显加速牙齿的移动速度。结论不同能量参数的CO2弱激光局部照射对减轻正畸牙齿疼痛程度及牙齿移动速度的影响不同。

Objective To explore the effects of different energy parameters of CO 2 low-intensity laser in reducing orthodontic pain and tooth movement during canine distal movement .Meth-ods Sixty patients were included .After the dentition aligned , 0.018 inch stainless steel round wire was used , the device for canine distal movement was elastomeric chain which produced o-riginally 150 g force, the right canine root area was irradiated by two different energy parame-ters of CO2 low laser, the left was control group .The impact of the CO 2 low-intensity laser local irradiation on the patients ’ level of pain was evaluated with the visual analog scale ( VAS ) . The distance of canine to molar was measured with a vernier caliper , efect of two kinds of ener-gy parameters of CO 2 low laser irradiation on the distal movement of the canine tooth movement speed was evaluated .Results The two energy parameters of CO 2 low laser reduced the degree of orthodontic tooth pain .The higher one effectively accelerated tooth movement , and the lower did not significantly accelerate the tooth movement .Conclusion Different energy parameters of CO2 low-intensity laser irradiation can produce different effects on orthodontic tooth pain and tooth movement speed .
