ABSTRACT
Fluoxetine is a widespread antidepressant medication, with side effects,
including xerostomia. In search of treatments to reduce discomfort, PBM
is one of the alternatives that has proven to be effective. This article
aims to demonstrate the clinical evolution of a female patient, L.R.O.,
55 years old, who reported severe oral discomfort due to lack of saliva.
The selected treatment was the Low Power Laser - EccoFibras with
vascular photobiomodulation, in radial artery for 30 minutes, wavelength
660nm and power of 100mW, with 180J energy delivery. After the first
treatment session, the patient reported improvement and satisfaction
and, due to the unpredictability of psychiatric discharge, she tried to
perform weekly applications. With each session, she reported a decrease
in symptoms, which encouraged her attendance. With the prevention of
xerostomia, the pacient achieved a clear increase in her quality of
life, demonstrating that vascular photobiomodulation can be an
interesting low-cost non-invasive treatment.
