Two studies being presented this week at the International Association for Dental Research (IADR) meeting in Seattle lend support to the clinical efficacy and safety of the Biolux Research light-accelerated orthodontics technology.
In the first, a team of researchers from University of Alabama at Birmingham; Mahidol University in Bangkok, Thailand; and private practices in North America evaluated the effect of the photobiomodulation device on the rate of tooth movement during the alignment phase of orthodontic treatment with fixed appliances, and included upper and lower arches in 73 test subjects and 17 controls. They found a statistically significant 2.3-fold increase in tooth movement in the patients treated with photobiomodulation.
In the second study, researchers from the University of Alabama at Birmingham evaluated whether using photobiomodulation in conjunction with fixed orthodontic appliances led to any significant change in root resorption. They used cone-beam CT to evaluate 20 patients before and after orthodontic treatment, and found no statistically significant in root length change at the end of treatment compared with the start of treatment, for either anterior or posterior teeth. They also found no clinically significant changes between root lengths more than 0.5 mm.
