Introduction: The purpose of this study was to determine the effect of low-level laser therapy on orthodontic pain after the first canine retraction force. Method: This single-blind split-mouth placebo-controlled randomized clinical trial was performed in 30 orthodontic patients requiring bilateral canine retraction in Shahed University. Once canine retraction was initiated, a single dose of diode laser radiation (660 nm, 80 MW, and 3.8 J/cm2 density, diameter of the optical fiber tip: 0/45cm2) was administered to a randomly selected maxillary or mandibular quarter for 30 s. The other quarter served as the placebo side and was treated using the same device without turning on the laser. On the first, second, fourth, and seventh days, the patients rated the pain they experienced on each side at home by using visual analog scale-based questionnaires. Changes in pain were analyzed using non-parametric analysiswith SPSS software. Results: In patients who experienced pain,a significant pain reduction was notedon the first and fourth days after low-level laser therapy on the experimental side compared to that on the placebo side (P <0.05). Conclusions: A single dose of diodelaser therapy (660nm)can be an efficient modality to reduce the orthodontic pain associated with canine retraction

Introduction: Finding a method to decrease orthodontic treatment time has been a concern for several authors. This study evaluated, clinically and radiographically, the influence of low-level laser therapy on the rate of orthodontic movement and dental tissue integrity. Methods: The sample included 11 individuals with class I malocclusion, requiring extraction of 4 first premolars. Gallium aluminum arsenide diode laser with a wavelength of 780 nm was used once a month during retraction mechanics, to irradiate the maxillary and mandibular canines on one side and compare them with the nonirradiated contralateral side, after spring activation, until canine retraction was completed. This was followed by movement measurement. Periapical radiographs were used to check for possible modifications in the supporting tissues and root surface of the displaced canines. Results: No differences in the rate of tooth movement were found between the irradiated and nonirradiated side on both dental arches. There was no resorption of the root and/or alveolar bone crest, maintaining the integrity of these tissues. Conclusions: Low-level laser therapy did not promote an increment on the rate of tooth movement and did not cause greater root and alveolar bone crest resorption than on the nonirradiated side with the used protocol.

Objectives. To assess the effectiveness of low-level laser therapy (LLLT) in reducing orthodontic pain after the application of orthodontic force (OF).Methods. A systematic search was conducted in the MEDLINE, EMBASE, Scopus, Cochrane Library, Web of Science, and EBSCOhost databases. The study included randomized clinical trials (RCT) which analysed the effectiveness of LLLT in reducing orthodontic pain assessed at 24 and 72 hrs after the application of OF. The risk of bias of the eligible trials was assessed using the Cochrane Collaboration’s risk of bias tool. Standard mean difference was calculated and pooled by meta-analysis using random effect models.Results.Of 467 identified articles, 20 RCT were finally included. In the risk of bias assessments, 13 studies presented a high risk, 5 an unclear risk, and 2 a low risk. The meta-analysis showed that in patients treated with laser versus placebo there was a difference in favour of LLLT in spontaneous pain 24 and 72 hrs after the installation of light archwires and spontaneous pain and chewing pain 24 and 72 hrs after the installation of elastomeric separators.Conclusions.LLLT proved to be effective in promoting a reduction in spontaneous and chewing pain after the application of OF; however, the poor quality of the evidence requires these results to be treated with caution.
