Objective: The aim of this case report is to describe Photobiomodulation Therapy (PBMT) as an alternative for the management of ageusia following infection by COVID-19.

Method and Materials: PBMT was performed using a 660 nm and 808 nm diode laser (1 J/point, 100 mW, 10 sec, 40 points on tongue) and taste perception recovery was assessed by a quantitative test with hyper-concentrated substances (acid, bitter, sweet and salt), using a 0-10 score. Taste tests were carried out before treatment, after 8 and 16 PBMT sessions.

Results: Positive evolution of taste perception recovery was shown throughout PBMT sessions, at 8 and 16 sessions, demonstrating improvement in taste perception.

Conclusions: PBMT using the parameters set for the present clinical case was shown to be effective, noninvasive and an option of therapy for the management of prolonged dysgeusia COVID-19 related.
