Placebo Comparator
Low-level laser therapy
Non laser ordinary red light
This group of patients was treated with a continuous wave diode laser device (830 nanometer, infrared) with a beam area of 0.002827 cm2 using the punctual method on the continuous emission mode at an output power of 50 milliwatts and a fluence of 707 Joules/cm2 six years before.
This group of patients was treated using the same method and equipment, except that a non laser ordinary red light, an output power of 0.1 Watt and a fluence of 1.41 Joules/cm2 and an irradiance value of 0.0002827 Watts/cm2 (the placebo), indistinguishable from the laser beam, was used. Therefore, the patients were blinded to which treatment they received.
