The sample will consist of 108 children of both sexes, aged between 5 and 12 years. The study participants will be randomly allocated, using a simple lottery method, with numbered papers, into three d
group 1 (G1) will undergo photobiomodulation with an infrared wavelength at a dose of 7 J per point
group 2 (G2) will undergo photobiomodulation with an infrared wavelength at a dose of 9 J per point. The study will be double-blind, meaning that the evaluator will be blinded to the intervention each
