The application of a low-level laser was made randomly on one of the two sides immediately after surgery and on two first days, with the following parameters: Laser GaAlAs at 810nm wavelength, energy density of 4 J / cm2, output power of 0.5 W On the control side, a handpiece was applied intraorally, but the laser was not activated.
Nhóm thử nghiệm được chiếu laser GaAlAs bước sóng 810nm, mật độ năng lượng 4 J / c m2, công suất 0,5 W. Ở nhóm chứng, bệnh nhân được đặt đầu laser nhưng không kích hoạt tia.
