“…On day 60, the total tooth movement distance was 4.39 mm for the laser group and 3.0 mm for the control group, which represents a statistically significant difference [P < 0.001]. In the third study (by Sousa et al [22]), maxillary canine distalization was performed with a NiTi closed spring on a fixed appliance. After randomization, laser irradiation [780 nm] was applied on 10 points of the canine on days 0, 3, and 7.…”

“…Doshi-Metha et al [23] chose 800 nm because the results of Takeda [31] and Bradley et al [32] had indicated significant biostimulatory effects on bone metabolism around this wavelength. For Cruz et al [17], Sousa et al [22], and Youssef et al [21], the reason is documented in the book by Marshall and Haywood [33]. In fact, infrared light has a low absorption by water, and as a result an increased penetration into irradiated tissues.…”

“…It has been suggested that scattering is responsible for an estimated 3 to 6% decrease of the energy level of the used lasers. In these studies, [17,[22][23][24], the ED of 5 J/cm 2 at each point around the irradiated tooth is lower, except in the Limpanichkul et al [20] study, in which the fluence is 25 J/cm 2 . The higher ED may be the reason they showed no difference between the experimental low level-intensity laser therapy subjects and the controls.…”

Purpose Orthodontic treatment can last between 2 and 3 years. These long treatment times can significantly decrease patient cooperation and yield adverse effects. This review aimed to evaluate the clinical effect of low-level laser therapy (LLLT) on the acceleration of orthodontic tooth movement. Materials and methods We searched the Cochrane Library, PubMed, and EMBASE and included only studies evaluating the effect of LLLT on orthodontic human tooth movement, according to inclusion criteria. Results We included thirteen studies (three controlled clinical trials [CCTs], five randomized clinical trials [RCTs], and five systematic reviews or meta-analyses). Six of the eight clinical trials showed a statistically significant effect on orthodontic tooth movement toward a low-level laser application. Conclusion Comparison between studies is difficult because of parameter variability (anchorage, orthodontic appliances, wavelength, and other laser parameters); however, LLLT may be an interesting method to accelerate orthodontic tooth movement. The highest-level studies show that LLLT can accelerate orthodontic movements, but other research must be pursued. This review of the literature seems to suggest concentrating future research regarding the relationship between LLLT and orthodontic tooth movement on wavelengths in infrared radiation approximately 780-810 nm, with a fluence of approximately 5 J/cm 2 .

IntroductionOrthodontic treatment involves moving tooth by force application and it requires a period of time. Prolonged orthodontic treatment can be a threat to oral hygiene and a source of trauma to oral tissue. Shortening the treatment time becomes one of the challenges for orthodontists. Several approaches have been described in the literature. Köle et al 1 reported that corticotomy accelerated experimental tooth movement in rats. Also Tuncay et al 2 and Young et al 3 reported that fiberotomy could achieve similar results in rats. Kanzaki et al 4 reported that local gene transfer of receptor activator of nuclear factor kappa-B ligand (RANKL) may activate osteoclast genesis and accelerate the tooth movement in periodontal tissue of rats. Also, it has been suggested that many substances such as platelet-poor plasma (PPP), platelet rich plasma (PRP), nitric oxide (NO) and prostaglandin E 2 (PGE 2 ) can accelerate experimental tooth movement. However, the side effect remains a major problem, making clinical application difficult. Chen et al 5 reported that electromagnetic wave treatment accelerated tooth movement in guinea pigs without adverse effects. Furthermore, it is shown by Nishimura et al 6 that by applying vibration, accelerated tooth movement can be achieved in beagle dogs without harm. Despite the fact that various methods have been shown to accelerate teeth movement, corticotomy is the only one applied in present. Nevertheless, the surgery represents a great burden for patients and there is also risk of tissue necrosis or infection. Therefore, a safer method is desired for orthodontic treatment. The effect of laser irradiation on orthodontic tooth movement has been attracting much attention over the past few years. Although it is indicated by numerous reports that tooth movement can be accelerated by diode laser irradiation, 7-9 there are only a few studies focused on other lasers. Ninomiya et al 10 revealed that neodymium-doped yttrium aluminium garnet (Nd:YAG) laser irradiation increased bone formation in femur metaphysis. Their results have shown the possibility of altering bone metabolism by laser irradiation. Therefore, in this experiment, The aim of this study is to evaluate the effects of low-level neodymium-doped yttrium aluminium garnet (Nd:YAG) laser irradiation on orthodontic tooth movement and histological examination. Methods: Eleven male Wistar rats (aged 10 weeks) were included. To produce experimental tooth movement in rats, 10 g force was applied to maxillary first molars with nickel titanium closed coil springs. Right molars were irradiated with Nd:YAG laser on days 0, 1, 2, 3, 7, 10, 14, 17, 21 and 24, while un-irradiated left molars were used as control. Distance between mesial side of second molar and distal side of first molar was measured on μCT image during tooth movement and the rats were sacrificed 4 weeks after the initiation of tooth movement. Results: The amount of tooth movement was significantly greater in the irradiation group (0.20 ± 0.06) than in the control group (0....
