Abstract: Objectives: Systemic review to know the effectiveness of low level laser therapy (LLLT). Material and Methods: Literature search was carried out from online databases including Medline, Web of Science, and Scopus between 2010 to 2019. Results: Following screening, 10 publications were eligible for the review. A meta-analysis could not be performed due to the heterogeneity of the studies. The results from the studies indicate that use of maintained dose of LLLT post therapy had substantial beneficial effects. Conclusions: The use of LLLT post operatively has certain positive effect. Evidence on accelerated wound healing and post-operative analgesia were profound but increased rate of bone formation were only limited to animal studies. Further research is warranted to reach absolute certainty.
