MLS® device (ASA Srl, Vicenza, Italy) IR laser with two synchronized sources (laser diodes) and a wavelength of 808 nm to deliver the intervention. The laser probe will be held vertically in contact with the skin to deliver the irradiation at three mandibular condyle points (front, behind and over) and one point at the external acoustic meatus. The irradiation will be applied with a laser bean of 3.14 cm² diameter for 14 seconds at each place using a pulse rate of 1500 Hz, pulse duration of 100ns, and energy density: 16 J/cm².

Visual analog scale (VAS), a grading scale range from 0 to 100 mm. 0 mm represented no pain or discomfort at all and 100 mm represented the greatest amount of pain or discomfort imaginable. Participant drew a line that intersects the grading scale to show the amount of pain or discomfort that he or she experienced at that moment. The assessor then used a ruler to measure the length from 0 mm to the intersecting line and recorded the value.
