Qatar University’s (QU) College of Dental Medicine (CDM) hosted a webinar series on ‘The Association between Periodontitis, a serious gum infection, and the severity of COVID-19’.
The event aimed to disseminate scientific findings to stakeholders and increase global visibility of CDM. It was attended by a number of researchers and dentists from Qatar and across the world.
The research team spearheaded by Dr Nadia Maarouf, associate consultant from Hamad Dental Center (HMC), and led by Dr Faleh Tamimi, professor at CDM, has shown a strong association between COVID-19 complications and periodontitis.
Researchers in Qatar investigated the records of 568 patients who suffered from COVID-19. Periodontitis causes a chronic inflammation that makes patients more susceptible to the severe and dangerous inflammation caused by COVID-19, the study revealed. They also found that a significant portion of the patients who suffered severe COVID-19 complications and even death had advanced periodontitis.
Upon adjusting for several factors such as patient’s age, gender and existence of chronic diseases, the link between periodontitis and COVID-19 complications proved to be statistically significant. The study revealed that patients with periodontitis were at least three times more likely to experience COVID-19 complications regardless of age, gender and other conditions. Periodontitis is mostly caused by poor oral hygiene and lack of maintenance of the dental condition.
