Researchers from the Rutgers School of Dentistry discovered the two oral solutions that can prevent sars-coV-2 coronavirus from reproducing in human cells.
According to the study published in Pathologens, a commercial mouthwash (with a combination of eucalyptus, menthol, methyl salicylic and thymol) and the prescribed chlorhexidine solution were able to neutralize the virus within seconds of its release at concentrations of a solution similar to those of common use.
The tests were carried out under laboratory conditions, with the greatest accuracy in the amount of oral solution for a simple use and in the time required to come into contact with the tissues of the oral cavity. As a result, the researchers stressed the need for more studies to confirm the result in real-world conditions as well.
The study was about finding a way to protect dentists from the particles that patients exhale and whether oral solutions could contribute to it. "As dentists, exposed to the patient's droplets, we decided to see if there was any way to reduce the blood load," said Eileen Hoskin, Assistant Professor at the School.
The researchers noted that the study does not suggest that the public should rest on the use of mouth solutions to treat the virus. More studies are needed in real-world conditions to determine whether the use of such solutions containing antiseptic agents with an active anti-virus effect two or three times a day could reduce the communicability of coronavirus.
Two more oral solutions, with povidone iodide and hydrogen peroxide, were also tested, which appeared potentially effective in inhibiting viral transmission although, unlike the first two solutions, they had a more pronounced corrosive effect on skin cells that act as a barrier to the virus.
Although previous research has shown the protection provided by various oral solutions against SARS-CoV-2 coronavirus, this study is the first to adjust the amount of solution, the time it takes to reach tissues and the damage it causes to skin cells in normal conditions in the oral cavity.
"Since SARS CoV-2 enters the body mainly from the nasal and oral cavity, scientists in Oral Biology should be part of such research because of their better understanding of infectious diseases transmitted through the mouth," commented Dr. Daniel H. Fine, head of research and chair of the school's Department of Oral Biology.
