Lasers have been identified as one of the preventive tools that can be utilised to prevent white spot lesion in orthodontic practice. The aim of this scoping review was to evaluate the current scientific literature on the use of lasers specifically to prevent white spot lesion in orthodontic cases. Search was performed in PubMed, Web of Science, Scopus and EBSCO databases from the past ten years. The records obtained were peruse considering specific inclusion and exclusion criteria. From the total of 1123 studies that were evaluated, 68 papers were included for this review. A variety of laser types has been reported including Er;YAG, Er,Cr:YSGG, Argon and CO2 lasers. CO2 laser has a good number of evidence of it’s positive result and can be suggested to be use in clinical practise. However, since most data for the other type of lasers were derived from in vitro studies, they must be interpreted with care. Randomised clinical trials would be beneficial to give more meaningful evidence for clinicians to adopt lasers in their practice.

Introduction: Coated archwires improve aesthetics during orthodontic treatment. However, little is known regarding their clinical benefit. This randomised controlled trial (RCT) compared the tooth alignment (TA), coating loss (CL), colour change (∆E*), and patient perception of coated archwires with their controls. Details of ∆E* and perception were reported in the second part of the articles. Methods: This RCT was done at three centres. Participants were randomised to receive one of four treatment interventions using 0.014” superelastic coated nickel-titanium archwires from Orthocare, RMO, G&H, and conventional uncoated 3M Unitek® archwires. These archwires were ligated during bonding and collected after eighth week and questionnaires were distributed to participants in the experimental groups only. After removal, TA and CL were measured using Little’s Irregularity Index and Autodesk® AutoCAD® software, respectively. At the time of this preliminary reporting, 84 participants had completed the trial. Two archwires fractured and were excluded. Therefore, 166 archwires (n = 166) were analysed. Results: Only non-extraction cases showed statistically significant differences in TA change between all groups (p = 0.005) and RMO showed significantly lowest mean of TA (1.5 mm). RMO and Orthocare showed significant TA change in the upper and lower arches (p = 0.037, 0.048). CL was found to be insignificant for both extraction and non-extraction cases (p >0.05). Comparison between upper and lower arches revealed no significant difference in TA and CL in all groups (p >0.05). Conclusion: From this preliminary analysis, Orthocare provides better TA in non-extraction cases despite highest percentage of coating loss.
