Low-level laser
Group A got LLLT with low-level diode laser 810-nm (invisible infrared) laser light generating 500 mw output, laser probe with 5 diodes of 100 mw each (500 mw in total) + guide light (EME brand, model; LIS 1050, 905 length of diode emission) as shown in Fig. Low-level laser used in our studyDiagram showing the points where both devices were used
