Mouthwash Could Reduce Spread of Coronavirus - Study Finds
Preliminary results in scientific studies by Cardiff University have found that rinsing with regular over the counter mouthwash could kill Coronavirus in saliva within 30 seconds.
These results which have yet to go through peer review come ahead of clinical trials set to investigate how effective mouthwash containing 0.007% of the antibacterial ingredient cetylpyridinium chloride (CPC) is at reducing the viral load of Coronavirus in our saliva. Early signs in the research are positive which backs up recently published studies into the role CPC-based mouthwashes could play in the slowing of the spread of Coronavirus.
"Whilst these mouthwashes very effectively eradicate the virus in the laboratory, we need to see if they work in patients and this is the point of our ongoing clinical study. It is important to point out the study won’t give us any direct evidence on viral transmission between patients, that would require a different type of study on a much larger scale." said Professor David Thomas from Cardiff University.
Tests have been carried out at the University laboratories in conditions designed to mimic the nose and throat of a human using a range of mouthwash brands including Dentyl. The next stage of this exciting development is to take these findings to clinical trial. This will help to determine whether these initial findings would be as effective on patients as they have been in lab conditions in reducing that viral load. The clinical trial is set to be carried out at University Hospital of Wales in Cardiff with results set to be published in early 2021.
Specialist Periodontologist Dr Nick Claydon spoke of the value of these early results:
"If these positive results are reflected in Cardiff University’s clinical trial, CPC-based mouthwashes such as Dentyl used in the in-vitro study could become an important addition to people’s routine, together with hand washing, physical distancing and wearing masks, both now and in the future."
If clinical trials are successful, the use of over the counter mouthwash could add another preventative method that the general public can use to help slow the spread of Covid-19 alongside regular hand washing with hand sanitiser and the use of social distancing and face masks in public spaces. This news comes in the same week that progress is being made with a second Coronavirus vaccine from Moderna which claims of 95% protection against the virus.
