Phototherapies for COVID-19-associated opportunistic oral infections.

Opportunistic infections are widely described in patients with novel coronavirus disease 2019 (COVID-19); however, very few studies have addressed those affecting the oral cavity. Given the lack of information on the clinical presentations and the available treatment options, the present study aimed to show a case in which a combination of antimicrobial photodynamic therapy (aPDT) and photobiomodulation therapy (PBMT) was used for the management of two concomitant COVID-19-associated opportunistic oral infections (oral pseudomembranous candidiasis and recurrent herpes labialis). Within 7 days and without any systemic drug administration, all the lesions resolved completely, and the patient no longer reported oral pain or discomfort. According to the current case report and taking into consideration the significant gaps in the knowledge and understanding of COVID-19, this combination of phototherapy modalities seems to be a promising tool for managing viral and fungal opportunistic oral infections.
