Corona and oral health .. a warning against “aggressive bacteria”

Corona patients with gum disease have a higher risk of developing serious complications of the disease.

Almost two years after the outbreak of the emerging epidemic of the Corona virus, there are still many dark sides to understanding the infection of the Corna virus, yet scientists continue to learn day after day about the effects of the coronavirus on the human body and its various organs.

It is now widely proven that advanced age, obesity, and cardiovascular disease significantly increase the risk of developing a potentially fatal infectious disease.

Several studies have also found counterintuitive but troubling associations with an increased risk of contracting coronavirus, such as poor oral health.

The study “The effect of oral health status on COVID-19 severity, recovery period and C-reactive protein values” published in the British Journal of Dentistry determined that those with poor oral hygiene in the case of COVID-19 had a greater risk of experiencing severe symptoms of infection.

A research entitled “The relationship between gingivitis and the severity of Covid-19 infection” revealed that Corona patients with periodontal disease are 3.5 times more likely to be hospitalized in the intensive care unit compared to those without it.

Even more shocking was that patients with periodontal disease infected with an epidemic pathogen are 9 times more likely to die than those without, according to the same survey.

Such studies raised the question about the relationship of disease caused by a respiratory virus to poor oral health, which was answered by researchers Sim K. Singrao and Alice Harding are, respectively, Senior Research Fellow and Specialist in Dental Care at the School of Ondotoology at the University of Central Lancashire, UK.

The two experts explained that poor oral health has been associated with the exacerbation of many other diseases, especially when it persists for a long time, noting that the main risk is dysbacteriosis, a condition that makes the bacteria in our oral cavity unharmed in aggressive pathogens.

If the bacteria become “harmful” they can begin attacking oral tissues, entering the bloodstream, nesting in other organs and causing inflammation, which in turn increases the risk of chronic disease.

According to Singrao and Harding, circulation of these bacteria can damage heart health, raise blood pressure, exacerbate diabetes, cause premature birth, arthritis, respiratory disease, neurodegeneration, and many more.

The two scientists also explained that patients with severe Covid have high levels of a specific inflammatory marker called CRP, and some also develop a “cytokine storm”, an asymmetric response of the immune system that can be much more severe than the coronavirus itself, leading to the deposition of Fluid in the lungs, leading to acute respiratory distress syndrome (ARDS) and/or multiple organ failure, all of which are fatal.

The study, published in the British Journal of Dentistry, highlights that even people with poor oral hygiene can have higher levels of C-reactive protein and cytokines, so it is thought that periodontal disease can also activate an inflammatory response similar to that caused by an epidemic pathogen.

In the case of MERS-CoV and other viral illnesses such as acute influenza, the potential combination with infection of bacterial origin is a known problem, as bacteria can in fact take advantage of our virus-weakened organism to attack us.

A study titled “Co-infection: potentially fatal and unexplored in COVID-19” published in the scientific journal The Lancet found that up to 50% of Covid patients who lost their lives had a bacterial co-infection.

With poor oral hygiene, we are more susceptible to aggressive bacteria that live in the mouth and that can reach the lungs more easily.

Furthermore, bacteria can alter the cells of the oral cavity that protect us from other viral and bacterial aggressions.

All this can increase the risk of infection with the Coronavirus and the development of the acute form of infection in case of infection.

For this reason, experts always recommend brushing your teeth twice daily (for two minutes each time) with fluoride toothpaste and making regular visits to the dentist.
