Cellular Effects Related to the Clinical Uses of Laser in Orthodontics
Dominguez, Angela Camacho / Castro, Paola Zúniga / Morales, Mónica Cardona
Some orthodontic procedures are improved by the therapeutic use of laser, bringing some advantages for both patient and practitioner, by either reducing the time of procedures or pain induced by the activation of devices during the treatment. This therapy deserves further analysis of the biological principles, to provide insight into 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 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 is a strong basis to explain the significant favorable clinical results reported.
