Association of past hospitalization due to COVID-19 with oral health and hygiene.

In 2000, the Surgeon General’s report highlighted that the mouth is a mirror for overall health of an individual and that disparities in oral health are directly proportionate to general health inequities. Among patients hospitalized due to COVID-19, diabetes and cardiovascular disease are the most common comorbidities; several studies support the association of these conditions with periodontal disease. This study’s main aim is to assess the disproportionate impact of the COVID-19 pandemic on populations from lower socioeconomic statuses. The study also aims to assess the association of self-reported periodontal disease with COVID-19 disease course and severity. A sample population of Indiana residents with positive diagnosis of SARS-CoV-2 were recruited. A validated survey tool was sent to this cohort inquiring about sociodemographic distribution; co-morbid conditions, current symptoms of “long haul COVID,” course of their COVID-19 infection; history of periodontal disease, existing periodontal disease symptoms, and oral hygiene habits. 209 individuals with a history of positive COVID test were returned to the survey, and association of participant characteristics and periodontal disease-related survey items with COVID-related survey items were evaluated using chi-square tests. Lower sense of smell ratings was associated with less education (p = 0.021), being unemployed/disabled (p = 0.008), worse health status (p
