Periodontal Disease: A Threat to Covid-19 Severity

PD is an inflammatory illness affecting tissues that surrounds teeth. Co morbidities linked with PD are age, smoking, diabetes, hereditary, poor oral hygiene. These factors have been linked with severity of COVID-19, caused by virus namely corona virus “SARS-CoV-2.” As dysbiotic, inflammation and comorbidities disturb general well-being, it is probable that “periodontal status indicates the risk of complication of COVID-19”. Patients with COPD have a higher risk of provocation with COVID. Pregnancies can be complicated with co infection of SARS-CoV-2 with periodontal disease. Diabetic people also have PD probably because they are more prone to contract infections and higher chances to develop COVID-19 can also be increased with obesity and its consequences. Researchers have proved that aging is linked with PD and severe COVID-19 along with these factors. Smoking is the major risk factor in PD which leads to increase in enzyme ACE2; it’s an important element for development of covid-19. Chronic inflammation of airways had showed a relation between periodontal disease and asthma with enhanced ACE2 and TMPRSS 2 expression, increased SARS COV-2 infection susceptibility and Covid19 morbidity. Rheumatoid arthritis and liver disease also correspond to the development of covid-19 along with periodontitis. Patients who had history of liver disease have more chances to get SARS-COV-2 by means of the ACE-2 receptor. Degree of immunosuppression is thought to play a part in the vulnerability to SARS-CoV-2 infection. Hence, knowing the link between periodontal disease and COVID-19 severity, can aid in identifying the risk groups and create recommendation. The goal of the this review paper is to explain in detail the co-relation between periodontal disease and covid19
