Some orthodontic procedures are improved by the therapeutic use of laser, that brings about some advantages, both for patient and practitioner, either reducing time of procedures or pain induced by the activation of devices during the treatment. Nonetheless, this therapy deserves further analysis of the biological principles, to get insight in the effects of laser on different cell lineages involved. The aim of this article is to provide a review of the literature about laser effects on fibroblasts, osteoblasts and osteoclasts, studied in animal models and eventually in human subjects. The review indicates that the application of low energy laser during orthodontic movement is safe in terms of the cellular effects and there are strong basis to explain the significant favorable clinical results reported.
