COVID-19: Mouthwash can kill coronavirus within 30 seconds, study finds | UK News



Mouthwash can kill COVID-19 within 30 seconds of being exposed to a laboratory, a scientific study has found.

These preliminary findings, which have yet to be reviewed, come before a clinical trial examining whether over-the-counter mouthwash can reduce levels. coronavirus in the patient’s saliva.

The study conducted in Cardiff The university found that mouthwash containing 0.07% of the ingredient cetipyridinium chloride (CPC) showed “promising signs” of reducing COVID-19.

These findings support another recently published study that found that CPC-based mouthwashes are effective in reducing the viral load of coronavirus.

The researchers conducted laboratory tests that mimicked the passage conditions of the nasopharynx and oropharynx using mouthwashes such as Dentyl.

A 12-week clinical trial at the University Hospital in Wales will now help determine the effectiveness of mouthwash in reducing the viral load of COVID-19 in patients’ saliva.

Dentyl will be the only mouthwash brand in the UK used in the study, and the findings will be published in early 2021.

Professor David Thomas of Cardiff University, who is leading the clinical trial, said: “Although this in vitro study is very encouraging and a positive step, more clinical research is now clearly needed.

“We need to understand whether the effect of over-the-counter mouthwash on the COVID-19 virus achieved in the laboratory can be replicated in patients, and we look forward to completing our clinical trial in early 2021.”

Dr. Nick Claydon, a periodontist, said the study was “very valuable.”

He said: “If these positive results are reflected in the University of Cardiff clinical trial, CPC-based mouthwashes such as Dentyl used in the in vitro study could become an important addition to people’s routine, along with washing. on the hands, physical distancing and wearing masks, both now and in the future. “
