Treatment duration is one of the major determinants for patients receiving orthodontic treatment. To avoid long treatment time, orthodontists have to design sound mechanics meeting the anchorage demands and delivering appropriate force system to the tooth and its supporting tissues. However, the more crucial factors related to the treatment efficiency may lie in the individual biological response which is still largely unknown, to the force system which orthodontists regularly delivered. Low level laser with specific power setting has been shown as a non-invasive adjunctive treatment without obvious side effect for facilitating orthodontic movement in some clinical studies. This article reviews mechanism, animal and clinical studies about low level laser therapy used orthodontics.
