“…Resulting in an average of 34% faster tooth movement. As cited above, these results are similar to those found in previous studies related to PBM and acceleration of tooth movement . Since the age selection was relatively wide for the present study, female patients aged more than 45 years may have presented the influence of osteoporosis on the tooth movement.…”

“…In our study, since criteria for patient selection included extruded molars with indication for intrusion, the majority of patients were mature adults seeking for a faster orthodontic treatment and prosthetic rehabilitation on the lower arch. PBM is known for its benefits including pain relief, increased blood microcirculation, modulatory effects on tissue physiology, biomechanical and proliferative activities . To the best of our knowledge, this is the first study to focus on PBM effects on bone remodeling and tooth movement in more mature patients.…”

“…Therefore, during orthodontic movement, high expression of these cytokines is found to promote bone resorption, mainly on the compression side [36,52,53]. In addition, IL-1β is an IL-6 induce and participate in the complex mechanism of mediators that regulate bone remodeling [32,54], by recruiting osteoclast cells and inducing bone resorption [31,55]. Similar results were found by Yanaguizawa et al [31] after insertion of mini screws, the bone trauma promoted by miniscrew installation also promote rise in IL-6 levels and PBM significantly promoted a further increase in this cytokine.…”

This study investigated the effects of photobiomodulation (PBM) on upper molar intrusion movement, regarding acceleration of orthodontic movement and its molecular effects. The sample consisted of 30 patients with indication of tooth intrusion for oral rehabilitation. Teeth were divided into three different groups: G1 (n = 10) pre‐molars without force or laser application (control); G2 (n = 10) upper molar intrusion; and G3 (n = 10) upper molar intrusion and PBM. On PBM treated molars, the teeth were irradiated with a low‐power diode laser (808 nm, 100 mW), receiving 1 J per point, density of 25 J/cm2, with application of 10 s per point, 10 points (5 per vestibular and 5 per palatal region). Orthodontic force of intrusion applied every 30 days and PBM was performed immediately, 3 and 7 days after force application for 3 months. Gingival crevicular fluid was collected at the same time periods as the laser applications and interleukins (IL) 1‐β, ‐6 and ‐8 were evaluated by enzyme‐linked immunosorbent assay. Clinical measures were performed monthly to verify the amount of intrusion. The levels of IL‐6, IL‐8 and IL‐1β increased under orthodontic force (G2 and G3) when compared to control group (G1), however, the cytokines levels were significantly higher after PBM (G3). The mean intrusion velocity was 0.26 mm/month in the irradiated group (G3), average duration of 8 months vs 0.17 mm/month for the non‐irradiated group (G2), average duration of 12 months. This study suggests that PBM accelerates tooth movement during molar intrusion, due to modulation of IL‐6, IL‐8 and IL‐1β during bone remodeling.

“…Two RCTs evaluated this outcome. 28,29 According to Samara et al, the patients treated with LLLT exhibited a significantly higher velocity of space closure by 0.22 mm/month than the non-radiated patients. 28 According to Arumughan et al, each round of laser application (21 days) accelerated the orthodontic tooth movement by 12.55% as compared to the conventional retraction technique.…”

Objectives. The aim of the paper was to appraise the current evidence of the effectiveness of low-level laser therapy (LLLT) in accelerating the tooth movement. Methods.A comprehensive search was performed in 9 databases up to June 2019. Only randomized controlled trials (RCTs) were included. The risk of bias was assessed using the Cochrane Collaboration tool. The quantitative data synthesis was attainable only for the studies evaluating the effect of laser on canine retraction; the qualitative description was used for the rest of the studies. The overall quality of evidence was rated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria. Results.A total of 25 RCTs were included in this review. The radiated upper canines showed a greater retraction -0.50 mm and 0.49 mm at months 2 and 3, respectively. The radiated lower canines showed a greater retraction -0.28 mm and 0.52 mm at months 2 and 3, respectively. No statistically significant differences were observed among the upper and lower canines after the 1 st month of retraction. When the GRADE approach was utilized, the overall quality of evidence limited confidence in the estimates. The qualitative description revealed enhanced tooth movement when LLLT was applied. The attrition bias was the main risk factor affecting the methodology of the studies.Conclusions. Low-level laser therapy can speed up the rate of the tooth movement. However, the overall quality of evidence ranged from low to very low and the clinical significance of the obtained statistically significant differences is questionable. Hence, more precise studies are needed. As discussed in this review, it is highly recommended to express and compare the laser dosage with the total number of joules applied per month rather than the previously used J/cm 2 . Moreover, the previous recommendation indicating that lower energy densities (2.5, 5 and 8 J/cm 2 ) are more effective than 20 and 25 J/cm 2 is misleading.
