Changes in salivary parameters, such as decreased flow, changes in pH and composition, can lead to changes in oral health. Saliva is responsible for the homeostasis of the oral cavity and is therefore directly related to the occurrence of caries, periodontitis, fungal and bacterial infections. These situations compromise the quality of life of the population and for this reason prevention and treatment strategies need to be studied and developed. Photobiomodulation is an alternative that has been increasingly practiced by health professionals. It consists of the application of light to a biological system that is capable of inducing a photochemical process, mainly in the mitochondria, thus stimulating the production of energy in the form of adenosine triphosphate (ATP), which can increase cellular metabolism and produce effects. as analgesia and tissue regeneration. In dentistry, studies using photobiomodulation have shown promise in improving some salivary parameters. This study aimed to compare the action of infrared light on salivary flow and pH, using two application techniques: extraoral (G1) and intra and extraoral (G2), with the application interval between the two techniques being 7 days
