The researchers said once again that widely available mouthwashes killed the Coronavirus, responsible for the Covid-19 disease, within 30 seconds of exposure under laboratory conditions.
The study this time from Cardiff University in the UK, which has not yet been peer reviewed or published in a medical journal, found that some mouthwashes could help kill Coronavirus in saliva.
According to the BBC, while research suggests that using mouthwash can help kill the virus in saliva, there is no evidence that it can be used as a treatment for coronavirus, as it won’t reach the airways or lungs.
“The ability of mouthwashes to inactivate SARS-CoV-2 in vitro was tested using a protocol capable of detecting reduced infectivity,” said the study authors. The mouthwashes have been laboratory tested under conditions designed to mimic the oral / nasal cavity in a test tube.
The researchers revealed that mouthwashes containing at least 0.07% cetypyridinium chloride showed “promising signs” of potential killing of the virus.
“This study adds to the emerging literature that several commonly available mouthwashes designed to fight gum disease can also inactivate the SARS-CoV-2 coronavirus (and other related coronaviruses),” study lead author Richard Stanton told the BBC.
According to the research team, the clinical trial will investigate whether it helps reduce levels of the virus in the saliva of Covid-19 patients at the Cardiff hospital, with results expected early next year.
Researcher David Thomas said the initial results were encouraging, but the clinical trial would yield no evidence on how to prevent transmission between patients.
“Although these mouthwashes very effectively eradicate the virus in the laboratory, we need to see if they work in patients and that’s the point of our ongoing clinical trial,” he said.
Another study published in the Journal of Medical Virology in October also revealed that some oral antiseptics and mouthwashes may have the ability to inactivate human coronaviruses.
