Mouth rinses are effective against Corona? What a new study from Bochum really means

A German team of researchers is, a commercially available mouth rinses, Sars-CoV can destroy 2. This is a gratifying knowledge which is, however, treated with caution.

Sars-Cov-2 with certain commercially available mouthwashes disable. The Virological and virologists from the research group Molecular and Medical Virology, Ruhr-University of Bochum, together with colleagues from Jena, Ulm, Duisburg-Essen, Nürnberg and Bremen in cell culture experiments, found out now. Their findings the researchers published in the journal “the Journal of Infectious Diseases”.

The application of Sars-Cov-2-effective mouthwashes may help, therefore, briefly, the virus load in the mouth and throat of Covid-19-patients in order to reduce any risk of Transmission of the corona virus. Could use the especially prior to dental and other medical treatments. For the treatment of a Covid-19-infection are mouth rinses, however, are not. Also, not to protect themselves from infection with the Virus to protect.

Eight mouth rinses in the cell culture test

The researchers tested substances eight mouth rinses with different ingredients that are available in pharmacies or drug stores available in Germany. They mixed each of the mouth rinse with virus particles, and a loading substance, which should reproduce the effect of saliva in the mouth. The mixture was then shaken for 30 seconds, to simulate the effect of the Gurgelns. They then used for the determination of the virus share therein, so-called Vero-E6 cells. You are especially susceptible to Sars-Cov-2.

All of the tested rinses reduced the initial virus content. Three mouth rinses reduced him even to the extent that after 30 seconds exposure , no more Virus in the mixture to find that:

  • Listerine Cool Mint
  • Iso-Betadine
  • Dequonal

The other tested mouth rinses Cavex Oral Pre-Rinse, Chlorhexamed Forte, Dynexidine Forte, Octenident and ProntOral were.

Flushing is only effective in the mouth virus production in cells is still more

The authors of the study suggest that mouth rinses are not suitable for the treatment of Covid-19-disease. “The gargle with a mouth rinse can not inhibit production of the virus in the cells,” explains Toni masters, one of the main authors of the study. It “could reduce the virus load in the short term where there is the greatest contagion potential is coming from, namely in the mouth-and throat – and that could be in certain situations, such as at the dentist or the medical care of Covid-19-patients useful.”

    The Bochum group is now examining the possibilities of a clinical study on the effectiveness of mouthwashes against Sars-CoV-2. In it, the scientists want to test whether the effect is also detected in patients and how long it lasts. Similar Work is ongoing in San Francisco; the Bochum Team with the US-American researchers in contact.
