Evaluation of Prophylactic Photobiomodulation Therapy in Patients With Osteosarcoma

The application of preventive TLBP will be performed with a laser device containing an aluminum phosphide and indium gallium diode (InGaAlP) emitting radiation in the red region of the electromagnetic spectrum (660 nm) with a power of 100mW and a beam area of 0.03 cm2 . An energy of 1J/point and an energy density of 33.3 J/cm2/point were determined, which will be applied punctually, with a distance between the points of 1cm, for 10s per point, totaling 9 points per region.
