Abstract

Objective: The aim of this study is to examine the relationship between periodontal disease and COVID-19 severity by retrospectively evaluating patient records and periodontal status.
Methods: 344 patients were included in the study. The severity of periodontal disease was determined as healthy, mild, moderate and severe according to NHANES criteria. The Covid-19 severity of the patients was grouped as asymptomatic/mild, moderate and severe according to whether the patients required hospitalization and intensive care.
Results: There was statistically significant relationship was observed between Covid-19 severity and periodontal status (p<0.001).
Conclusion: Periodontitis and the severity of Covid-19 increases, regardless of systemic diseases and age.
