Oral lesions related to the novel Coronavirus Disease 2019 (COVID-19) have been increasingly described; however, clinical and epidemiological information is still scant. Although a diversity of therapeutic strategies for the management of these lesions are present in the literature, one can note a lack of standardization and doubtful effectiveness. Thus, the present study aimed to report a series of cases in which a combination of antimicrobial photodynamic therapy (aPDT) and photobiomodulation therapy (PBMT) was used for orofacial lesions in patients suffering from COVID-19. It was noted, in all cases, a marked improvement in tissue repair and pain relief within a few days; moreover, the patients recovered their orofacial functions satisfactorily. Based on the present series of cases and having in mind the conspicuous lack of information on the different aspects of COVID-19, the protocol which combined aPDT with PMBT seemed to be effective in the management of COVID-19-related orofacial lesions.
