Examine the role of systemic inflammation from COVID-19 in exacerbating pre-existing periodontal conditions

Numerous systemic illnesses and ailments have been related to periodontitis. Frequent studies have been conducted to investigate the relationship between COVID-19 and periodontitis due to their common comorbidity.An increasing amount of research indicates that periodontitis may raise the chance of contracting COVID-19 and its sequelae. The immunological states such as cytokines and chemokines coagulation conditions, underlying diseases besides genetic, sex, microbiological factors, dental care, and personal conservations might be at play in the correlation between the two illnesses. Male gender was shown to be related to both higher severity of COVID-19 and higher overall mortality, as well as with both severe (SP) and non-severe (NSP) types of periodontitis. Patients with diabetes type 2 and hypertension had an increased risk of COVID-19 problems and periodontal inflammation. The immune system's response to periodontitis may be enhanced by the production of receptors TMPRSS2, and ACE2 that SARS-CoV2 uses to infect cells. The potential presence of periodontitis could potentially contribute to SARS-CoV-2 infection via the CD147 pathway, given the elevated levels of CD147 expression in the oral epithelial cells within the subgingival region of periodontal pockets. Periodontal infections were found in the respiratory systems of individuals with severe COVID-19, and there is evidence that periodontitis may further raise the risk of COVID-19 problems by changing the coagulation pathways. IL-6, MMP8, and IL-1β demonstrated a predictive value of 100%, suggesting their reliability in diagnosing periodontitis.Patients with periodontal disease who had COVID-19 had substantially higher blood levels of HbA1c, WBC, D-dimer, and CRP. Systemic inflammation from COVID-19 can exacerbate pre-existing periodontal conditions, potentially increasing the severity of both diseases and impacting patient outcomes.
