“…7 Thus, accelerating orthodontic tooth movement and the resulting shortening of the treatment duration would be quite beneficial. To date, several novel modalities have been reported to accelerate orthodontic tooth movement, including low-level laser therapy, 8,9 pulsed electromagnetic fields, 10 electrical currents, 11 corticotomy, 12,13 distraction osteogenesis, [14][15][16] and mechanical vibration. 17 However, pertinent results are inconclusive, and some are unreliable, which may bias clinicians' understandings and mislead clinical practice.…”

Objective: To evaluate the effectiveness of interventions on accelerating orthodontic tooth movement. Materials and Methods: We searched the databases of PubMed, Embase, Science Citation Index, CENTRAL, and SIGLE from January 1990 to August 2011 for randomized or quasirandomized controlled trials that assessed the effectiveness of interventions on accelerating orthodontic tooth movement. The processes of study search, selection, and quality assessment were conducted independently in duplicate by two review authors. Original outcome data, if possible, underwent statistical pooling by using Review Manager 5. Results: Through a predefined search strategy, we finally included nine eligible studies. Among them, five interventions were studied (ie, low-level laser therapy, corticotomy, electrical current, pulsed electromagnetic fields, and dentoalveolar or periodontal distraction). Six outcomes were evaluated in these studies (ie, accumulative moved distance or movement rate, time required to move tooth to its destination, anchorage loss, periodontal health, pulp vitality, and root resorption). Conclusion: Among the five interventions, corticotomy is effective and safe to accelerate orthodontic tooth movement, low-level laser therapy was unable to accelerate orthodontic tooth movement, current evidence does not reveal whether electrical current and pulsed electromagnetic fields are effective in accelerating orthodontic tooth movement, and dentoalveolar or periodontal distraction is promising in accelerating orthodontic tooth movement but lacks convincing evidence.

“…The application of Low-level laser therapy is a noninvasive alternative that has shown to be effective not only to reduce pain caused by the application of separators (Burns et al, 2001;Aihara et al, 2006;Cattaneo et al, 2009;Altan et al, 2012;Artés-Ribas et al, 2013;Bister & Meikle, 2013) in the initial stages of treatment (Chen et al, 2011), during canine retraction (Cruz et al, 2004;d'Apuzzo et al, 2013) and following activation of orthodontic final archwires (Dominguez et al, 2012) but also to reduce the overall orthodontic treatment time Domínguez-Camacho & Velásquez-Cujar, 2010;Doshi-Mehta & Bhad-Patil, 2012;Domínguez & Velásquez, 2013).…”

DOMINGUEZ, Á.; LEÓN, P.; ARISTIZABAL. J. F. Effect of low level laser therapy on local bone resorption during orthodontic treatment. A randomized controlled trial. Int. J. Odontostomat., 10(3):483-490, 2016. ABSTRACT:The aim of this study was to assess whether the application of low-level laser therapy (LLLT) during the first stage of orthodontic treatment has an effect on local bone resorption and is detectable at the systemic level by measuring deoxypyridinoline levels (Pyrilinks) in urine. This was a randomized (1:1), double-blind, active-controlled, parallel-group trial. 28 adult patients who were going to start orthodontic treatment were randomly divided into the control group (n: 13) and the experimental group (n: 15), the latter of which received LLLT. All of the subjects underwent testing of urine samples: the first one on the day before the beginning of orthodontic treatment (T0), and the second one 5 days after bracket placement to measure Pyrilinks values (Dpd/Cr) in urine. Group differences were evaluated with Student's paired t-test. At the beginning of the study, the Pyrilinks were in the normal range for 53.57 % of the patients, and 46.43 % had elevated values according to the normal ranges. Only taking into account the normal values at (T0), the average Pyrilinks for control group (T0) were 5.75± 1.20 nM/mM, (T1): 6.02±3.00 nM/mM. For experimental group, (T0) was 5.71± 0.72, and it was 6.63± 0.73 in (T1).There were no significant differences in the Pyrilinks changes. (p= 0.75). In the experimental group levels raised statistically significant (p = 0.009). LLLT on patients starting orthodontic treatment with normal Pyrilinks levels have a statistically significant increment on their levels 5 days post irradiation.

“…This process results in beneficial therapeutic outcomes including but not limited to the alleviation of pain or inflammation, immunomodulation, and promotion of wound healing and tissue regeneration.^ [1]. PBM therapy was found to have multiple clinical benefits, which includes reducing pain [2][3][4][5][6][7], improving wound healing [8][9][10][11], accelerating bone healing [12][13][14][15][16][17], promoting osteointegration [18], facilitating orthodontic tooth movement [19][20][21][22][23][24][25][26], stimulating bone formation [27][28][29][30][31], and improving periodontal tissue repair and decreasing inflammation and root resorption [23,26,32]. The light sources were laser or a light-emitting diode (LED).…”

Light transmittance of the periodontium

Objective Photobiomodulation (PBM) therapy stimulates cells and regulates their activities. However, the actual accumulated dose that the cells receive is still unknown because the transmittances of the light on various tissues are not available. The objective of this study is to determine the light transmittances of the oral tissues. Methods Tissue samples of gum, cortical bone, and trabecular bone were prepared from ten Yucatan pigs' mandibles. Both the transmittance and the attenuation coefficient in the Beer-Lambert law were used to characterize the materials' light transmittance behavior. A higher attenuation coefficient indicates lower transmittance. The samples were tested with the light within the wavelength ranging from 420 to 1050 nm. The light intensity measured with and without the samples was used to calculate the transmittance. Results The result showed that the Beer-Lambert law can be used to estimate the transmittance if the light surface loss is eliminated. Among the three tissues, the gum has the highest attenuation coefficient and the trabecular bone has the lowest. The attenuation coefficient is higher at lower wavelengths for all three tissues, and is lower and keeps plateaued at the wavelength from 700 to 1050 nm. The surface loss rate of gum is higher at lower wavelengths. The light intensity within the tested range does not affect the transmittance.

Abstract: Our findings suggest that LILT does accelerate human teeth movement and could therefore considerably shorten the whole treatment duration.
