To evaluate the effect of diode laser use on experimental orthodontic tooth movements.
Thirty Rattus norvegicus albinus Wistar were divided into three equal groups (n = 10), two experimentals and one control. Applying 20 g orthodontic force were attached to the maxillary incisors of the rats in all groups. Low dose laser was applied to the surrounding tissues of the maxillary incisors of the rats in the experimental groups. Two exposure times for laser irradiation were used for seven days: t = 12 min (energy dose = 72 J) and t = 9 min (energy dose = 54 J) by a 0.1 W DEKA brand diode laser with wavelength of 980 nm.
Osteoclastic activation increased in the 72 J group when compared to control group and decreased in comparison to the 54 J group. Osteoblastic activation was decreased in the 72 J group when compared to the control group and increased in comparison to the 54 J group.
Applying 54 J laser energy has been found effective to accelerate the orthodontic tooth movement.
评估二极管激光应用于实验性正畸牙齿移动的效果。
将 30 只白化 Wistar 大鼠随机分为三组（n = 10），两组实验组，一组对照组。所有组的大鼠上颌切牙均施加 20 g 的正畸力。实验组大鼠上颌切牙周围组织应用低剂量激光照射，激光照射时间为 7 天，两种暴露时间：t = 12 min（能量剂量 = 72 J）和 t = 9 min（能量剂量 = 54 J），使用波长为 980nm 的 0.1 W DEKA 品牌二极管激光。
与对照组相比，72 J 组破骨细胞活性增加，与 54 J 组相比减少。与对照组相比，72 J 组成骨细胞活性降低，与 54 J 组相比增加。
发现应用 54 J 激光能量可有效加速正畸牙齿移动。
