When it come to LLLT and orthodontics, positive evidence is consistent.
While I have assumed that low level laser therapy applied to orthodontic treatment would be beneficial, it is still gratifying to see research such as this:
A short clip: “The inflammation markers inducible NO synthase (iNOS), cyclooxygenase (COX)-2 and interleukin (IL)-1 showed stronger expression in 5 and 10 J/cm2 therapy at days 1 and 5, but decreased in expression at day 7.”
While I don’t pretend to understand all of the above, what I do recognize is that the “healing cascade” took about 7 days. Based on all previous study of mine, this would mean that a safe illumination frequency would be one treatment per week. Regardless of their dosages used, I would stick with my conservative dosage of 1-2 joules of energy per area of 9 square centimeters.
