Chandigarh: A
study conducted by Dr. HSJ Institute of Dental Science and Hospital, Punjab
University in collaboration with Institute of Microbial Technology (CSIR)-
Structural Biology Laboratory have claimed that one of the most routinely used
mouth rinses, Chlorhexidine could kill 99.9% of SARS CoV2 virus within 30
seconds of being exposed to it in a laboratory.
It must be mentioned that Chlorhexidine gluconate is a
germicidal mouthwash that reduces bacteria in the mouth.
The study, titled "Chlorhexidine: An effective
anti-Covid mouth rinse" was supported by Hyderabad Headquartered Dr. Reddy's
Laboratories and Design Innovation Centre, Punjab University.
Studies have shown that the Covid-19 virus colonizes in
the oral and nasal cavities. Mouth rinses can be an efficient way to reduce
colonization and possibly reduce the spread of infection.
According to the study, Chlorhexidine gluconate mouth
rinses in 0.2% concentration kill more than 99.9 percent of Covid-19 virus, in
a minimal contact period of 30 seconds.
However, the study is in the preprint server and yet to
be peer-reviewed.
" We found that a mouth rinse with the required
concentration of Chlorhexidine killed coronavirus within 30 seconds after being
exposed in a laboratory. In our current study, we used only Chlorhexidine.
However, it is to be seen whether a commercial mouth wash is as effective as
was found in the study because of the other ingredients found in a mouth wash.
the initial results from the lab studies and need to be verified through
clinical studies. " stated Dr. Ashish Jain from Dr. HSJ Institute of
Dental Science and Hospital.
The aim of the study was to provide insight into the
efficacy of 0.2 percent of Chlorhexidine against Covid-19 through laboratory
analysis.
