DNA damage in blood cells exposed to low‐level lasers

In regenerative medicine, there are increasing applications of low‐level lasers in therapeutic protocols for treatment of diseases in soft and in bone tissues. However, there are doubts about effects on DNA, and an adequate dosimetry could improve the safety of clinical applications of these lasers. This work aimed to evaluate DNA damage in peripheral blood cells of Wistar rats induced by low‐level red and infrared lasers at different fluences, powers, and emission modes according to therapeutic protocols.
