Primary Outcome Measures

Name	Time	Method
It is expected that, with the application of a non-invasive therapy with low intensity laser, which will consist of the systemic photoactivation of the carotid artery and the photobiomodulation of the taste buds and salivary glands, it will present results of reducing the manifestation of dysgeusia as a sequel of the coronavirus (COVID-19).

Secondary Outcome Measures

Name	Time	Method
It is expected that, with the application of Laser Irradiation of Blood (ILIB) associated with photobiomodulation, there will be a faster reversal of dysgeusia symptoms in the group that will be applied laser therapy compared to the group that will only be simulated with light therapy. The time of dysgeusia reversal in both groups will also be observed.
