BARBOSA, Kevan Guilherme Nóbrega et al. Analgesia during orthodontic treatment with low intensity laser: systematic review. Rev. dor [online]. 2013, vol.14, n.2, pp.137-141. ISSN 1806-0013.

BACKGROUND AND OBJECTIVES: Pain is a typical symptom during early orthodontic treatment. This study aimed at reviewing the literature on the use of low intensity laser to relieve pain during orthodontic treatment. CONTENTS: Titles, summaries and articles were searched in the following databases: Pubmed/Medline, Cochrane Library, LILACS and Scielo. Three researchers have independently searched using defined inclusion and exclusion criteria. Eight clinical trials were included and six have observed significant pain relief after therapeutic laser. CONCLUSION: There are scientific evidences that low intensity laser decreases pain symptoms during dental movements after the placement of orthodontic elastics and after orthodontic adjustments. Its use by dentists is a feasible alternative for inducing less adverse effects as compared to anti-inflammatory analgesics, being indicated for allergic patients, children and patients with systemic impairment. However, there is the need for further scientific investigations using well-defined protocols.
