Low-Level-LASER Therapy - LLLT - for the treatment of oral myofascial pain. A systematic review of the last thirteen years

A systematic review of randomized clinical trials - rcts - on low-level-laser therapy (lllt) for the treatment of oral myofacial pain was conducted. methods: we searched the literature (medline via pubmed, cochrane central and other sources) from 1999 to 2012 in order to identify rcts on lllt for myofacial pain. two review authors (cr-b and sj) compiled and evaluated the included studies. we analyzed 6 rcts (n=223) on lllt for myofacial pain. a high heterogeneity of applied dosages was observed. conclusion: we found no evidence to support the use of lllt for the treatment of myofascial pain. dosage and regimen of administration are a major concern in future studies. we suggest the use of core outcomes in order to compare laser therapy results with other short-term therapeutic strategies for myofacial pain.
