As the number of cases of the new type of corona virus in the world approaches 150 million, a new study by Canadian scientists found that gingivitis increases the risk of death from Covid-19 by 8.8 times. In addition, people suffering from gingivitis were 3.5 times more likely to be hospitalized due to Covid-19 and 4.5 times more likely to need a ventilator, it was noted.

Researchers at McGill University in Canada said they found a strong link between gingivitis (periodontitis), a common disease, and severe Covid-19. People with gingivitis are 8.8 times more likely to die from Covid-19, experts said, adding that oral hygiene can reduce the risk.

However, individuals suffering from gingivitis were 3.5 times more likely to be hospitalized due to Covid-19 and 4.5 times more likely to need a ventilator.

Professor of the McGill School of Dentistry, said: “looking at the results of our study reveals the importance of good oral health in the prevention and management of covid-19 complications. There is a very strong association between Periodontitis and the outcome of the disease,” he said.


Gingivitis (periodontitis) can occur as a serious infection due to the accumulation of bacteria between the teeth and gums. If left untreated, it causes painful abscesses and tooth loss. In later cases, it damages the lower jaw bone.

Good oral hygiene, which includes brushing teeth twice daily, flossing and regular checkups, can prevent gingivitis, scientists say. “Periodontitis has been recognized as a risk factor for many diseases, both orally and systemic,” said, co-author of the study. If left untreated, this inflammation can spread throughout the body. The scientists also found links between the condition and heart disease, diabetes and respiratory diseases. There is also an association between gingivitis and the risk of miscarriage and increased pregnancy complications,” he said.


The researchers used data from Hamad Medical Corporation, which includes nine hospitals in Qatar, as part of the study. In this context, the medical records of 568 patients were examined.

“In Qatar, medical and dental records have been digitized, which makes it possible to collect data and do this research quickly,” said. The study also assessed” various factors such as demographic, medical or mental health factors were taken into account.”

The study, on the other hand, found that biomarkers indicating inflammation were present at significantly higher levels in the blood of covid -19 patients who also had gingivitis.


“In the severe Covid-19 patients, the corona virus causes an inflammatory response that can lead to complications such as intubation and even death,” said. Our University research shows that periodontitis can exacerbate this,” he said.

The senior author of the study, Dr. “Gingivitis patients already get Covid-19 with high levels of inflammation in their bodies,” said. Covid-19 disease also causes hyperinflation in the body, which puts them at a disadvantage and makes them more susceptible to the severe consequences of the disease,” he concluded.
