Abstract

Introduction: Application of low-level laser therapy (LLLT) in reducing the pain associated with orthodontic treatment is still debated. Hence, the aim of this systematic review is to reconnoiter the effect of LLLT in pain allied with different orthodontic procedure.

Methods: Literature search in Scopus, PubMed and Science direct data bases was performed by two independent reviewers. In addition, manual hand search and references were checked to fine relevant studies. Systematic review and meta-analysis were conducted using the data entered into electronic data bases until 31st August 2018.

Results: On the basis of the different data bases search, 22 studies were included for the systematic review and total 5 studies were selected for meta-analysis. Mean pain score and standard deviation were used to evaluate the effectiveness of LLLT relation with pain in orthodontic treatment. There is significant positive association with laser application in reducing pain in elastomeric separator placement in 24 hours (P value 0.01) and 72 hours (P value 0.02). However, in terms of canine retraction, LLLT does not showed significant difference in reducing pain.

Conclusion: More clinical trials in the effectiveness of low-level laser therapy in relation with pain perception of orthodontic treatment is necessary to define better specificity of conceivable interaction.
