Popis: To evaluate the reduction in the salivary viral load using oral antiseptic mouthwashes in patients testing positive for COVID-19.Sixty-three individuals were recruited after testing positive for COVID-19 by real-time RT-PCR assay and divided into 5 groups. Group 1 received sterile water, group 2 received 1.5% hydrogen peroxide solution (HP), group 3 received 0.12% chlorhexidine (CHX), group 4 received 0.1% sodium hypochlorite solution (NaClO), and group 5 received sequential rinses using CHX and HP. After collecting the initial saliva sample, individuals were asked to use the designated mouthwash for 1 min. Additional saliva samples were collected immediately after rinsing, 15, and 30 min after rinsing. Real-time RT-PCR assays for RNA detection of SARS-CoV-2 were performed on the saliva samples.There were no significant differences among the experimental groups and the control group in any period. Compared to the baseline values, there was a significant reduction in the number of copies of SARS-CoV-2 after 30 min in group 2 and immediately after the initial mouthwash in group 4.No experimental group demonstrated a significant reduction in the viral load compared to the control group.
